-Always attach ground clamp to the work piece or worktable as close to the weld area as possible.
-Do not touch the welding wire and the ground or grounded work piece at the same time.
-Do not use a welder to thaw frozen pipes.
Fumes and Gases
-Fumes emitted from the welding process displace clean air and can result in injury or
death.
-Do not breathe in fumes emitted by the welding process. Make sure your breathing air is clean and
safe.
-Work only in a well-ventilated area or use a ventilation device to remove welding fumes from the
Page 4 of 44
environment where you will be working.
-Do not weld on coated materials (galvanized, cadmium plated or containing zinc, mercury or
barium). They will emit harmful fumes that are dangerous to breathe. If necessary, use a ventilator,
respirator with air supply or remove the coating from the material in the weld area.
-The fumes emitted from some metals when heated are extremely toxic. Refer to the material safety
data sheet for the manufacturer’s instructions.
-Do not weld near materials that will emit toxic fumes when heated. Vapors from cleaners, sprays
and degreasers can be highly toxic when heated.
UV and IR Arc Rays
The welding arc produces ultraviolet (UV) and infrared (IR) rays that can cause injury to
your eyes and skin. Do not look at the welding arc without proper eye protection.
-Always use a helmet that covers your full face from the neck to top of head and to the back of each
ear.
-Use a lens that meets ANSI standards and safety glasses. For welders under 160 Amps output,
use a shade 10 lens; for above 160 Amps, use a shade 12. Refer to the ANSI standard Z87.1 for
more information.
-Cover all bare skin areas exposed to the arc with protective clothing and shoes. Flame-retardant
cloth or leather shirts, coats, pants or coveralls are available for protection.
-Use screens or other barriers to protect other people from the arc rays emitted from your welding.
-Warn people in your welding area when you are going to strike an arc so they can protect
themselves.
Fire Hazards
Do not weld on containers or pipes that contain or have had flammable, gaseous or liquid
combustibles in them. Welding creates sparks and heat that can ignite flammable and
explosive materials.
-Do not operate any electric arc welder in areas where flammable or explosive materials are
present.
-Remove all flammable materials within 35 feet of the welding arc. If removal is not possible, tightly
cover them with fireproof covers.
-Take precautions to ensure that flying sparks do not cause fires or explosions in hidden areas,
cracks or areas you cannot see.
-Keep a fire extinguisher close in the case of fire.
-Wear garments that are oil-free with no pockets or cuffs that will collect sparks.
-Do not have on your person any items that are combustible, such as lighters or matches.
-Keep work lead connected as close to the weld area as possible to prevent any unknown,
unintended paths of electrical current from causing electrical shock and fire hazards.
-To prevent any unintended arcs, cut wire back to ¼" stick out after welding.
Hot Materials
Welded materials are hot and can cause severe burns if handled improperly.
-Do not touch welded materials with bare hands.
-Do not touch torch nozzle after welding until it has had time to cool down.
Sparks/Flying Debris
Welding creates hot sparks that can cause injury. Chipping slag off welds creates flying
Page 5 of 44
debris.
-Always wear protective apparel: ANSI-approved safety glasses or shield, welder’s hat and ear
plugs to keep sparks out of ears and hair.
Electromagnetic Field
-Electromagnetic fields can interfere with various electrical and electronic devices such as
pacemakers.
-Consult your doctor before using any electric arc welder or cutting device
-Keep people with pacemakers away from your welding area when welding.
-Do not wrap cable around your body while welding.
-Wrap MIG gun and ground cable together whenever possible.
-Keep MIG gun and ground cables on the same side of your body.

DESCRIPTION
The Cornwell MMWMP242DVI is an inverter-powered, dual voltage, wire feed welder for flux core and
MIG welding plus a DC stick welder. It features a Synergic LCD control that allows the operator to select
process and weld settings. It comes complete with a regulator and gas hose for easy connection for MIG
welding plus a weld cable and electrode holder for DC stick welding. Directly connect this unit to a 230V
NEMA 6-50R receptacle or attach the supplied 120V adapter cord to operate off of 120V power. It is
designed to weld materials as thin as 24 gauge all the way up to 3/8" in a single pass. The Spool Gun
(B model optional purchase item MMWEZFSG2) is capable of welding aluminum with 4" spools of
aluminum wire. This unit can also perform lift start DC TIG welding (B model optional purchase item
MMWACTT2V) on steel and stainless-steel materials. Argon shielding gas and a TIG filler rod would also
be required for TIG welding.
This unit is intended to be used on a 50-amp 230V AC circuit or 120V, 20A AC circuit, without the use of
an extension cord. If an extension cord is necessary for your application, use the appropriate size and
length of extension cord that will handle 50 amps the entire length of the extension. We highly
recommend talking with a qualified electrician for cord size recommendations. This unit is supplied with a
NEMA Class 6-50P plug and will require a NEMA Class 6-50R receptacle. Do not remove the power
plug. Use the supplied 120V adapter when running off 120V power.
Inverter-based welding provides a smoother arc, increases efficiency, and provides better control than
non-inverter welding machines.

LCD SYNERGIC CONTROL
The LCD Synergic Control sets and operates the welder based on selections the operator makes in
weld process and material selections.
MIG TORCH
The welding wire is driven through the welding cable and torch to the work piece. It is attached to the
drive system. The trigger activates the drive motor.
TIG TORCH (OPTIONAL WITH MMWMP242DVIB)
The TIG torch transfers welding power from the welding power source to the tungsten for the
purpose of TIG welding. It also delivers the shielding gas from the welding power source to the
SPOOL GUN (OPTIONAL WITH MMWMP242DVIB)
The Spool Gun is typically used for welding aluminum. The soft aluminum wire has a hard time feeding
consistently in the standard MIG torch. Load 4in. spools of aluminum wire in the spool gun for easy and
consistent feeding of aluminum wire.
ELECTRODE HOLDER AND CABLE
The Electrode Holder holds the stick welding electrode. The cable most often connects to the Positive (+)
weld output connection for stick welding.
Page 8 of 44
POWER CORD AND PLUG
Plug this unit into a 230V, 50-amp circuit breaker power supply when operating on 230V. If running
on 120V power using the supplied 120V power cord adapter, plug this unit into a 120V, 20-amp
circuit breaker power supply.
INERT GAS REGULATOR AND HOSE
The Inert Gas Regulator installs on the shielding gas cylinder for MIG welding with solid wires. The
regulator controls the compressed gas and allows you to adjust the flow rate of the gas. The gas hose
connects to the regulator/flow gauge and delivers the shielding gas from the shielding gas bottle to the
welder.
MULTI-FUNCTION ADJUSTMENT/SELECTOR KNOB
The Multi-Function Adjustment/Selector Knob is used by the operator to interact with the LCD Synergic
Control. It is used for the selection and adjustment of welding processes, materials, and selections within
the LCD Synergic Control screen.
WELDING VOLTAGE CONTROL
The voltage control allows the operator to make manual voltage adjustments to the LCD Synergic
programming.
GROUND CABLE AND CLAMP
The ground cable and clamp are attached to the work piece to complete the circuit allowing the flow of
current needed to weld.
INSTALLATION
Electrical Shock
•
High voltage danger from power source! Consult a qualified electrician for proper
installation of receptacle. This welder must be grounded while in use to protect the
operator from electrical shock.
•
Do not remove grounding prong or alter the plug in any way. Use only the supplied
adapter between the plasma cutter's power cord and the power source receptacle. Make
sure the POWER switch is OFF when connecting your welder’s power cord directly to a
properly grounded 230 VAC, 60 HZ, Single Phase, 50 Amp input power supply. Or, when
using the supplied 120V adapter, connect the 120V Adapter to a properly grounded 120V,
20 Amp input power supply.
1. POWER REQUIREMENT 230V - AC single phase 230V (220-240V) 50/60 HZ fused with a
50-amp time delayed fuse or circuit breaker is required. DO NOT OPERATE THIS UNIT if the
ACTUAL power source voltage is less than 215 volts AC or greater than 240 volts AC.
2. POWER REQUIREMENT 120V - AC single phase 120V (110-130V) 50/60 HZ fused with a
20-amp time delayed fuse or circuit breaker is required. DO NOT OPERATE THIS UNIT if the
ACTUAL power source voltage is less than 110 volts AC or greater than 130 volts AC.
2.1
When connecting this unit to 120V power, connect the 120V adapter cord to the
power cord pigtail that is attached to the machine.
3. EXTENSION CORD - We do not recommend an extension cord because of the voltage drop
produced. This drop, in voltage can affect the performance of the welder. If you need to use an
extension cord, check with a qualified electrician and your local electrical codes for your specific
area.
Page 9 of 44
4. INSTALL THE WIRE ROLLER - The wire roller has been factory installed. However, check to
make certain the correct wire groove is in place to accommodate the size of wire you are using.
Open the wire feed compartment. Adjust the drive roller according to the following steps. See
Figure 2 about the wire feeder structure:
Figure 2

4.1
Open the door to the welder drive compartment.
4.2
Remove the drive tension by loosening the Drive Tension Adjuster (1) and moving the
Drive Tension Adjustor away from the Drive Tension Arm (2). Lift the Drive Tension
Arm away from the Drive Roller (3).
4.3
If there is wire already installed in the welder, roll it back onto the wire spool by
hand-turning the spool clockwise. Be careful not to let all the wire come out of the rear
end of the inlet guide tube. Hold onto it or the wire spool will unspool itself. Put the
end of the wire into the hole on the outside edge of the wire spool and bend it over to
hold the wire in place. Remove the spool of wire from the drive compartment of the
welder.
4.4
Remove the drive roller by turning the drive roll knob (3) counterclockwise. Carefully
slide the drive roll assembly off of the drive shaft. This drive roll assembly consists of
three pieces. The outer drive roll, inner drive roll, and a key. Be careful not to
misplace the key.
4.5
Based on the wire diameter, select the correct groove. When installing the drive roller,
the number stamped on the drive roller for the wire size you are using should be
facing you. Push the Drive Roller onto the Drive Roller Shaft.
4.6
Reinstall the Drive Roller knob and tighten clockwise.
4.7
Close the door to the welder drive compartment.
Electrical Shock
•
Electric shock can kill! Always turn the POWER switch OFF and unplug the power cord
from the AC power source before installing wire.
NOTE: Before installing, make sure that you have removed any old wire from the torch
assembly. This will help to prevent the possibility of the wire jamming inside the gun liner.
Page 10 of 44
NOTE: Be very careful when removing the welding nozzle. The contact tip on this welder is live
whenever the torch trigger is pulled. Make certain power is turned OFF.
5. INSTALL THE WIRE - We recommend the usage of .023, .030 & .035 MIG wire, or .030 and
.035 flux core wire, on this unit.
5.1
Select welding wire - Both four-inch or eight-inch wire spools of .023, .030, or .035
wire can be used on this welder.
NOTE: Burn-through can occur if you attempt to weld mild or stainless steel thinner than 24
gauge.
NOTE: Remove all rusted wire from your wire spool. If the whole spool is rusty, discard it.
5.2
Installing the wire.
5.2.1
Remove the nozzle and contact tip from the end of the torch assembly.
See Figure 3.
5.2.2
Make sure the proper groove on the drive roller is in place for the wire
installed. If not, change the drive roller as described in INSTALL THE
WIRE ROLLER above.
5.2.3
Remove the packaging from the spool of wire and then identify the
leading end of the wire secured on the edge of the spool. DO NOT
UNHOOK IT AT THIS TIME.

5.2.6
Setting the wire spool tension. a) Turn the spool of wire with one hand.
b) Increase the spool tension by tightening (turn clockwise) the wing
nut while turning the spool. Turn the spool while tightening the wing nut
until the spool slows down and you feel a slight drag. Stop tightening
the wing nut; you may need to repeat these steps until proper spool
tension is achieved.
5.2.7
If TOO MUCH tension is applied to the wire spool, the wire will slip on
the drive roller or will not be able to feed at all. If TOO LITTLE tension
is applied, the spool of wire will want to unspool itself when the trigger
is released. Readjust the spool tension using the wing nut as
necessary to correct for either problem.
5.2.8
With the welder disconnected from the power source, remove the
leading end of the wire from the spool. Hold on to it securely, so as
not to allow unspooling or tangling of the wire as it will result in tangled
wire and feeding problems.
Page 12 of 44
5.2.9
Cut off any bent portion of the wire using a wire cutter.
5.2.10
Loosen the tension adjusting knob holding the drive tension arm in
place and lift the tension arm up off the drive roller.
5.2.11
Insert the wire into the inlet guide tube and feed it across the drive
roller and into the torch assembly about six inches.
-Make certain that the welding wire is actually going into the torch liner. If not, the wire will jam up in
the mechanism.
5.2.12
Line the wire up with the correct groove in the drive roller. Place the
drive tension arm back above the drive roller.
5.2.13
Place the drive tension adjustment arm back in place.
5.2.14
Tighten (turn clockwise) the drive tension adjusting knob until the
tension roller is applying enough force on the wire to prevent it from
slipping in the drive rollers. DO NOT OVER TIGHTEN.
5.2.15
NOW YOU CAN LET GO OF THE WIRE.
5.2.16
Plug in the welder power cord and turn the welder ON. Set the voltage
switch to the voltage setting recommended for the gauge metal that is
to be welded. Refer to the set-up chart on the back side of the drive
compartment door.
-The welding wire is electrically hot when the power is on and the torch trigger is activated.
5.2.17
Set the WIRE SPEED control to the middle of the wire speed range.
5.2.18
Straighten the MIG torch cable and pull the trigger in the gun handle to
feed the wire through the torch assembly. When at least one inch of the
wire sticks out past the end of the torch, release the trigger.
5.2.19
Turn the power switch to the OFF position.
5.2.20
Select a contact tip stamped with the same diameter as the wire being
used. NOTE: Due to inherent variances in flux core welding wire, it may
be necessary to use a contact tip one size larger than your flux core
wire, if wire jams occur.
5.2.21
Slide the contact tip over the wire (protruding from the end of the
torch). Thread the contact tip into the end of the torch and hand-tighten
securely.
5.2.22
Install the nozzle on the torch assembly.
5.2.23
Cut off excess wire that extends past the end of the nozzle more than
1/4 inch.
5.2.24
Turn the welder ON.
Page 13 of 44
6. SETTING THE DRIVE ROLL TENSION
•
Arc flash can injure eyes! To reduce the risk of arc flash, make certain that the wire
coming out of the end of the torch does not come in contact with the work piece, ground
clamp, or any grounded material during the drive tension setting process or arcing will
occur.
6.1
Press the trigger on the torch.
6.2
Turn the drive tension adjustment knob clockwise until the wire seems to feed
smoothly without slipping.
7. GAS INSTALLATION
Shielding gas cylinders and high-pressure cylinders can explode if damaged, so treat them
carefully.
•
•
•
•
•
Never expose cylinders to high heat, sparks, open flames, mechanical shocks or arcs.
Do not weld on the cylinder.
Always secure cylinder upright to a cart or stationary object.
Keep cylinders away from welding or electrical circuits.
Use the proper regulators, gas hose and fittings for the specific application.
7.1
Polarity Changing - When MIG wire is used, shielding gas is required and the polarity
on this unit needs to be electrode positive.
7.1.1
Electrode Positive for MIG Welding - The Weld Power Cable (see
Figure 8) should be connected to the positive (+) weld output
connection on the front of the machine. The ground cable would then
be connected to the negative (-) weld output connection.
7.1.2
Electrode Negative for Flux Core Welding - The Weld Power Cable
should be connected to the negative (-) weld output connection on the
front of the machine. The ground cable would then be connected to the
positive (+) weld output connection. Refer to the polarity setting label
inside the wire compartment.
7.1.3
Connect one end of the gas hose to the gas hose connection on the
back of the welder. Use a wrench to snug up the connection.

Connect the other end of the gas hose to the gas hose connection on
the supplied regulator/flow gauge. Use a wrench to snug up the
connection.
7.1.5
Before installing the regulator, it is good practice to make certain no
debris is in the gas bottle connection. Rotate the bottle so the gas
connection is not pointing toward you or any other person. Turn the
valve on the gas bottle clockwise and quickly close. This quick thrust of
gas will clear any debris in the connection. Connect the regulator to the
gas bottle connection. Use a wrench to snug up the connection.
7.1.6
Open the Gas Bottle Valve on the cylinder of gas.
7.1.7
Turn the Gas Flow Adjuster on the regulator so that the gas flow rate is
set at approximately 20 CFH. Make certain you are reading the correct
scale on the gauge.
NOTE: Slowly open the cylinder valve by turning it counter-clockwise until the cylinder pressure
gauge registers on the first gauge of the regulator. Turn the adjustment knob clockwise (right)
slowly to increase gas flow to 20 CFH. To reduce the gas flow, turn the adjustment
counter-clockwise (left). The gas valve is located on the back panel of the welder and activated
by the trigger. Gas flow should be heard when the trigger is activated. No gas flow will result in
a harsh arc with excessive spatter; a smooth weld bead will be difficult to obtain. Avoid
unnecessary gas loss by closing the tank valve when finished welding.
Page 15 of 44
7.1.8
Gas Selection
Different materials require different shielding gases when MIG welding.
(Refer to the set-up chart inside the wire feed compartment.)
Mild Steel: Use 75% Argon and 25% CO2 for reduced spatter and
reduced penetration for thinner materials. DO NOT USE Argon gas
concentrations higher than 75% on steel. The result will be extremely
poor penetration, porosity, and brittleness of weld.
Mild Steel: Use CO2 for deeper penetration but increased spatter. (A
CO2 regulator adapter will be needed.)
Stainless Steel: Use a mixed gas consisting of Helium, Argon, and
CO2.
Aluminum or Bronze: Use 100% Argon.

MIG OPERATION
•
High voltage danger from power source! Consult a qualified electrician for proper
installation of receptacle. This welder must be grounded while in use to protect the
operator from electrical shock.
•
Do not remove grounding prong or alter the plug in any way. Use only the supplied
adapter between the plasma cutter's power cord and the power source receptacle. Make
sure the POWER switch is OFF when connecting your welder’s power cord directly to a
properly grounded 230 VAC, 60 HZ, Single Phase, 50 Amp input power supply. Or, when
using the supplied 120V adapter, connect the 120V Adapter to a properly grounded 120V,
20 Amp input power supply.
1. POWER SWITCH - The power switch supplies electrical current to the welder. Whenever the
power switch is in the ON position, the welding circuit is activated. ALWAYS turn the power
switch to the OFF position and unplug the welder before performing any maintenance.
2. HOLDING THE TORCH - The best way to hold the welding torch is the way it feels most
comfortable to you. While practicing using your new welder, experiments holding the torch in
different positions until you find the one that seems to work best for you.
3. POSITION OF THE TORCH TO THE WORK PIECE - There are two angles of the torch nozzle in
relation to the work piece that must be consider when welding.
3.1
Angle a can be varied, but in most cases the optimum angle will be 60 degrees, the
point at which the torch angle is parallel to the work piece. If angle A is increased,
penetration will increase. If angle A is decreased, penetration will decrease also.
3.2
Angle B can be varied for two reasons: to improve the availability to see the arc in
relation to the weld puddle and to direct the force of the arc.
3.3
DISTANCE FROM THE WORK PIECE - If the nozzle is held off the work piece, the
distance between the nozzle and the work piece should be kept constant and should
not exceed 1/4 inch or the arc may begin sputtering, signaling a loss in welding
performance.
3.4
TUNING IN THE WIRE SPEED - This is one of the most important parts of wire
welder operation and must be done before starting each welding job or whenever the
voltage setting, or wire diameter is changed.
EXPOSURE TO A WELDING ARC IS EXTREMELY HARMFUL TO THE EYES AND SKIN!
Prolonged exposure to the welding arc can cause blindness and burns. Never strike an arc
or begin welding until you are adequately protected. Wear flame-proof welding gloves, a
heavy long-sleeved shirt, trousers without cuffs, high topped shoes, and an ANSI approved
welding helmet.
Page 27 of 44
3.5
Connect the Ground Clamp to a scrap piece of the same type of material which you
will be welding. It should be equal to or greater than the thickness of the actual work
piece, and free of oil, paint, rust, etc.
3.6
Select a heat setting.
3.7
Hold the torch in one hand. Hold the wire just off the work piece. (See the previous
section, HOLDING THE TORCH, if you are uncertain of the angle at which you will be
welding.)
3.8
Set the wire feed speed based on the thickness of material and the set-up chart on
the back side of the wire feeder door.
3.9
Lower your welding helmet and pull the trigger on the torch and let the wire feed into
the work piece to start an arc, and then begin to drag the torch toward you.
3.10
LISTEN! If the arc is sputtering, increase the wire speed slightly and try again.
Continue increasing the wire speed adjustment until you achieve a smooth buzzing
sound. If the wire seems to "pound" into the work piece, decrease wire speed slightly
and try again. Use the wire speed control to slightly increase or decrease the heat
and penetration for a given voltage setting by increasing or decreasing the wire speed
slightly. Repeat this tune-in procedure if you select a new voltage setting, a different
wire diameter, or a different roll of wire.
4. WELDING TECHNIQUES
EXPOSURE TO A WELDING ARC IS EXTREMELY HARMFUL TO THE EYES AND SKIN!
Prolonged exposure to the welding arc can cause blindness and burns. Never strike an arc
or begin welding until you are adequately protected. Wear flame-proof welding gloves, a
heavy long-sleeved shirt, trousers without cuffs, high topped shoes, and an ANSI approved
welding helmet.
ELECTRIC SHOCK CAN CAUSE INJURY OR DEATH! To prevent ELECTRIC SHOCK, do not
perform any welding while standing, kneeling, or lying directly on the grounded workpiece.
4.1
Moving the Torch - Torch travel refers to the movement of the torch along the weld
joint and is broken into two elements: direction and speed. A solid weld bead requires
that the welding torch be moved steadily and at the right speed along the weld joint.
Moving the torch too fast, too slow, or erratically will prevent proper fusion or create a
lumpy, uneven bead.
Travel direction is the direction the torch is moved along the weld joint in relation to
the weld puddle. The torch is either PUSHED into the weld puddle or PULLED away
from the weld puddle.
Page 28 of 44
For most welding jobs you will pull the torch along the weld joint to take advantage of
the greater weld puddle visibility.
Travel speed is the rate at which the torch is being pushed or pulled along the weld
joint. For a fixed heat setting, the faster the travel speed, the lower the penetration
and the lower and narrower the finished weld bead. Likewise, the slower the travel
speed, the deeper the penetration and the higher and wider the finished weld bead
will be.
4.2
Types of Welding Beads - As you become more familiar with your new welder and
better at laying some simple weld beads, you can begin to try some different weld
bead types.
The STRINGER BEAD is formed by traveling with the torch in a straight line while
keeping the wire and nozzle centered over the weld joint. See following figure.
The WEAVE BEAD is used when you want to deposit metal over a wider space
than would be possible with a stringer bead. It is made by weaving from side to
side while moving with the torch. It is best to hesitate momentarily at each side
before weaving back the other way.
4.3
Welding Positions
The FLAT POSITION is the easiest of the welding positions and is most commonly
used. It is best if you can weld in the flat position, if at all possible, as good results are
easier to achieve.
Page 29 of 44
The HORIZONTAL POSITION is performed very similarly to the flat weld except that
angle B (see HOLDING THE TORCH) is such that the wire, directed more toward the
metal above the weld joint, is to help prevent the weld puddle from running downward
while still allowing slow enough travel speed. A good starting point for angle B is
about 30 degrees DOWN from being perpendicular to the work piece.
VERTICAL POSITION it is easier for many people to pull the torch from top to bottom.
It can be difficult to prevent the puddle from running downward. Pushing the torch
from bottom to top may provide better puddle control and allow slower rates of travel
speed to achieve deeper penetration. When vertical welding, angle B (see HOLDING
THE TORCH) is usually always kept at zero, but angle A will generally range from 45
to 60 degrees to provide better puddle control.
The OVERHEAD POSITION is the most difficult welding position. Angle A (see
HOLDING THE TORCH) should be maintained at 60 degrees. Maintaining this angle
will reduce the chances of molten metal falling into the nozzle. Angle B should be held
at zero degrees so that the wire is aiming directly into the weld joint. If you experience
excessive dripping of the weld puddle, select a lower heat setting. Also, the weave
bead tends to work better than the stringer.
4.4
Multiple Pass Welding
Butt Weld Joints When butt welding thicker materials; you will need to prepare the
edges of the material to be joined by grinding a bevel on the edge of one or both
pieces of the metal being joined. When this is done, a “V” is created between the two
pieces of metal that will have to be welded closed. In most cases more than one pass
or bead will need to be laid into the joint to close the “V”.
Page 30 of 44
Laying more than one bead into the same weld joint is known as a multiple-pass weld.
The illustrations in the following figure show the sequence for laying multiple pass
beads into a single “V” butt joint.
NOTE: WHEN USING SELF-SHIELDING FLUX-CORE WIRE it is very important to
thoroughly chip and brush the slag off each completed weld bead before making
another pass or the next pass will be of poor quality.
Fillet Weld Joints. Most fillet weld joints, on metals of moderate to heavy thickness,
will require multiple pass welds to produce strong joint. The following figure will show
the sequence of laying multiple pass beads into a T fillet joint and a lap fillet joint.
4.5
Spot Welding
There are three methods of spot welding: Burn-Through, Punch and Fill, and Lap.
Each has advantages and disadvantages depending on the specific application
as well as personal preference.
Page 31 of 44
4.5.1 The BURN-THROUGH METHOD welds two overlapped pieces of metal
together by burning through the top piece and into the bottom piece. With
the burn-through method, larger wire diameters tend to work better than
smaller diameters. Wire diameters that tend to work best, with the
burn-through method are 0.035 inch self-shielding flux-core wire. Do not use
0.030 inch self-shielding flux core wires when using the burn-through
method unless the metal is VERY thin or excessive filler metal build-up and
minimal penetration is acceptable. Always select the HIGH heat setting with
the burn-through method and tune in the wire speed prior to making a spot
weld.
4.5.2 The PUNCH AND FILL METHOD produces a weld with the most finished
appearance of the three spot weld methods. In this method, a hole is
punched or drilled into the top piece of metal and the arc is directed through
the hole to penetrate into the bottom piece. The puddle is allowed to fill up
the hole leaving a spot weld that is smooth and flush with the surface of the
top piece. Select the wire diameter, heat setting, and tune in the wire speed
as if you were welding the same thickness material with a continuous bead.
4.5.3 The LAP SPOT METHOD directs the welding arc to penetrate the bottom
and top pieces, at the same time, right along each side of the lap joint seam.
Select the wire diameter, heat setting, and tune in the wire speed as if you
were welding the same thickness material with a continuous bead.
5. SPOT WELDING INSTRUCTIONS
5.1
Select the wire diameter and heat setting recommended above for the method of spot
welding you intend to use.
5.2
Tune in the wire speed as if you were going to make a continuous weld.
5.3
Hold the nozzle piece completely perpendicular to and about 1/4 inch off the work
piece.
5.4
Pull the trigger on the torch and release it when it appears that the desired
penetration has been achieved.
5.5
Make practice spot welds on scrap metal, varying the length of time you hold the
trigger, until a desired spot weld is made.
5.6
Make spot welds on the actual work piece at desired locations.
DC STICK OPERATION
•
High voltage danger from power source! Consult a qualified electrician for proper
installation of receptacle. This welder must be grounded while in use to protect the
operator from electrical shock.
•
Do not remove grounding prong or alter the plug in any way. Use only the supplied
adapter between the plasma cutter's power cord and the power source receptacle. Make
Page 32 of 44
sure the POWER switch is OFF when connecting your welder’s power cord directly to a
properly grounded 230 VAC, 60 HZ, Single Phase, 50 Amp input power supply. Or, when
using the supplied 120V adapter, connect the 120V Adapter to a properly grounded 120V,
20 Amp input power supply.
1. SETTING UP THE WORK PIECE
1.1 Welding positions - There are two basic positions, for welding: Flat and Horizontal. Flat
welding is generally easier, faster, and allows for better penetration. If possible, the work
piece should be positioned so that the bead will run on a flat surface.
1.2 Preparing the Joint- Before welding, the surface of work piece needs to be free of dirt,
rust, scale, oil, or paint or it will create brittle and porous welds. If the base metal pieces
to be joined are thick or heavy, it may be necessary to bevel the edges with a metal
grinder; the correct bevel should be around 60 degree. See the following illustration:
Based on different welding positions, there are different welding joints. See the following illustration
for more information.
Page 33 of 44
2. GROUND CLAMP CONNECTION
Clear any dirt, rust, scale, oil, or paint on the ground clamp. Make certain you have a good solid
ground connection. A poor connection at the ground clamp will waste power and heat. Make sure
the ground clamp touches the metal.
3. ELECTRODE
The welding electrode is a rod coated with a layer of flux. When welding, electrical current flows
between the electrode (rod) and the grounded metal work piece. The intense heat of the arc
between the rod and the grounded metal melts the electrode and the flux.
4. SELECTING THE PROPER ELECTRODE
There is no golden rule that determines the exact rod or heat setting required for every situation.
The type and thickness of metal and the position of the work piece determine the electrode type
and the amount of heat needed in the welding process. Heavier and thicker metals require more
amperage. It is best to practice your welds on scrap metals which match the metal you intend to
work with to determine correct heat setting and electrode choice. See the following helpful
trouble shooting tips to determine if you are using a correct electrode.
4.1
When the proper rod is used:
4.1.1 The bead will lay smoothly over the work without ragged edges.
4.1.2 The base metal puddle will be as deep as the bead that rises above it.
4.1.3 The welding operation will make a crackling sound similar to the sound of
eggs frying.
4.2
When a rod is too small is used:
4.2.1 The bead will be high and irregular.
Page 34 of 44
4.2.2 The arc will be difficult to maintain.
4.3
When the rod is too large:
4.3.1 The arc will burn through light metals.
4.3.2 The bead will undercut the work.
4.3.3 The bead will be flat and porous.
4.3.4 The rod may be freeze or stick to the work piece.
Note: The rate of travel over the work also affects the weld. To ensure proper penetration and
enough deposit of rod, the arc must be moved slowly and evenly along the weld seam.
5. SETTING THE AMPERAGE CONTROL
The welder has an infinite current control. It is capable of welding with electrodes up to 3/32”
diameter. It is best to practice your welds on scrap metals which match the metals you intend to
work with to determine correct setting for your job. The electrode type and the thickness of the
work piece metal determine the amount of heat needed in the welding process. Heavier and
thicker metals require more voltage (amperage), whereas lighter and thinner metals require less
voltage (amperage). Consult the welding electrode packaging for recommended welding
amperage range.
6. WELDING TECHNIQUES
The best way to teach yourself how to weld is with short periods of practice at regular intervals.
All practice welds should be done on scrap metal that can be discarded. Do not attempt to make
any repairs on valuable equipment until you have satisfied yourself that your practice welds are
of good appearance and free of slag or gas inclusions.
6.1
Holding the electrode
The best way to grip the electrode holder is the way that feels most comfortable to
you. Position the electrode to the work piece when striking the initial arc it may be
necessary to hold the electrode perpendicular to the work piece. Once the arc is
started the angle of the electrode in relation to the work piece should be between 10
and 30 degrees. This will allow for good penetration, with minimal spatter.
EXPOSURE TO A WELDING ARC IS EXTREMELY HARMFUL TO THE EYES AND SKIN!
Prolonged exposure to the welding arc can cause blindness and burns. Never strike an arc
or begin welding until you are adequately protected. Wear flame-proof welding gloves, a
heavy long-sleeved shirt, trousers without cuffs, high topped shoes, and an ANSI approved
welding helmet.
ELECTRIC SHOCK CAN CAUSE INJURY OR DEATH! To prevent ELECTRIC SHOCK, do not
perform any welding while standing, kneeling, or lying directly on the grounded workpiece.
6.2
Striking the arc
Scratch the work piece with the end of electrode to start arc and then raise it quickly
about 1/8-inch gap between the rod and the work piece, see following picture:
Page 35 of 44
It is important that the gap be maintained during the welding process and it shouldn’t
be too wide or too narrow. If it’s too narrow, the rod will stick to the work piece. If it’s
too wide, the arc will be extinguished. It needs much practice to maintain the gap.
Beginners may get sticker or arc extinguishing. When the rod is stuck to the work
piece, gently rock it back and forth to separate them. If not, a short circuit will occur
and it will break the welder. A good arc is accompanied by a crisp, cracking sound
(eggs frying). To lay a weld bead, only two movements are required: downward (as
the electrode is consumed) and in the direction the weld is to be laid, as in the
following figure:
6.3
Types of weld bead
The following paragraphs discuss the most commonly used arc welding beads.
The stringer bead is formed by traveling with the electrode in a straight line while
keeping the electrode centered over the weld joint.
Stringer Bead
Weave Bead
The weave bead is used when you want to deposit metal over a wider space than
would be possible with a stringer bead. It is made by weaving from side to side while
moving with the electrode. It is best to hesitate momentarily at each side before
weaving back the other way.
Page 36 of 44
6.4
Welding position
Flat position is the easiest of the welding positions and is most commonly used. It is
best if you can weld in the flat position if at all possible, as good results are easier to
achieve.
Horizontal Position
Flat Position
The horizontal position is performed very much the same as the flat weld except that
the angle is different such that the electrode, and therefore the arc force, is directed
more toward the metal above the weld joint. This more direct angle helps prevent the
weld puddle from running downward while still allowing slow enough travel speed to
achieve good penetration. A good starting point for your electrode angle is about 30
degrees DOWN from being perpendicular to the work piece.
6.5
Judge the good weld bead
When the trick of establishing and holding an arc has been learned, the next step is
learning how to run a good bead. The first attempts in practice will probably fall short
of acceptable weld beads. Too long of an arc will be held or the travel speed will vary
from slow to fast (see following).
A. Weld speed is too fast.
B. Weld speed is too slow.
C. Arc is too long.
D. Ideal weld.
A solid weld bead requires that the electrode be moved slowly and steadily along the
weld seam. Moving the electrode rapidly or erratically will prevent proper fusion or
create a lumpy, uneven bead.
6.6
Finish the bead
As the coating on the outside of the electrode burns off, it forms an envelope of
protective gases around the weld. This prevents air from reaching the molten metal
and creating an undesirable chemical reaction. The burning coating, however, forms
slag. The slag formation appears as an accumulation of dirty metal scale on the
finished weld. Slag should be removed by using a chipping hammer.
Page 37 of 44
PEENING THE SLAG FROM A WELD JOINT CAUSES SMALL CHIPS OF METAL TO FLY
THROUGH THE AIR! Metallic chips flying through the air can cause eye injury or injury to other
parts of the head, hands or exposed portions of the body. Wear goggles or safety glasses with
side shields and protect the hands and other exposed parts of the body with protective garments,
or if possible, work with a shield between the body and the work piece.
The intense heat produced at the arc sets up strains in the metal joined by welding.
Peening the weld not only removes the scale left behind in the welding but relieves
the internal strains developed by the heating and cooling process.
DC TIG OPERATION
