Duty Cycle
The rated Duty cycle refers to the amount of welding that can be done within an amount of time. It is easiest to look at your welding time
in blocks of 10 Minutes and the Duty Cycle being a percentage of that 10 Minutes. If welding at 130 Amps with a 30% Duty Cycle, within
a 10 Minute block of time you can weld for 3 Minutes with 7 Minutes of cooling for the welder. If the duty cycle is exceeded and the
breaker is tripped, allow the unit to cool for a minimum of 15 Minutes. To increase the duty cycle you can turn down the Voltage Output
control. Going above 130 Amps will yield a lower duty cycle.

Installing Wire Spool
The Eastwood MIG175 can be used with either a 4”or an 8” Wire Spool. To use the larger 8” spool an included adaptor is necessary.
To install a 4” Wire Spool:
1. Open the door of the welder and remove the wing nut (Fig. 2G), spacer (Fig. 1G), and 8in Spool Adaptor (Fig. 3G)
from the Wire Spool Spindle.
2. Slide the 4” Wire Spool onto the spindle and reinstall the spacer and the wing nut and place the 8in Spool Adaptor
(Fig. 3G) in a safe place if it is needed in the future.
3. To set the tension on the wire, tighten the wing nut till there is a slight resistance to spinning
FIG. G-1
the wire spool on the spindle. If the tension is set too loose the wire spool will spin on the
shaft and unspool all of the wire. If the tension is too tight, the drive roller will have issues
pulling the wire off the spool and some slipping may occur.
NOTE: Hold exposed wire end to keep the spool from unraveling.
To install an 8” Wire Spool:
1. Open the door of the welder and remove the wing nut, spacer, and 8” Spool Adaptor
from the Wire Spool Spindle.
FIG. G-2
2. Slide the 8” Wire Spool Adaptor into the center of the wire spool.
3. Slide the 8” Wire Spool Adaptor with the wire spool installed onto the spindle and
reinstall the spacer and the wing nut.
4. To set the tension on the wire, tighten the wing nut till there is a slight resistance to spinning
the wire spool on the spindle. If the tension is set too loose the wire spool will spin on the shaft
and unspool all of the wire. If the tension is too tight, the drive roller will have issues pulling the
wire off the spool and some slipping may occur.

Connecting the Welder to a Power Source
2G
1. 1⁄4 turn and test again.
2. You do not want too much tension on the tension roller as it will tend to deform the wire. Just enough to feed
the wire without slipping
3. Once the wire has emerged from the tip of the gun, turn the machine OFF and replace the tip and nozzle.
Shielding Gas Flow Adjustment
After connecting your Shielding Gas Regulator, the gas flow rate needs to be adjusted so that the proper amount of Shielding Gas
is flowing over your weld. If there is too little gas flow there will be porosity in your welds as well as excessive spatter, if there is
too much gas flow you will be wasting gas and may affect the weld quality. The included regulator has 2 gauges on it; the gauge
on the left is your flow rate while the gauge on your right is your tank pressure.
1. Open your Shielding Gas tank valve all the way.
2. Adjust the knob on the regulator to ~30 CFH.
3. Turn on the welder and trigger the torch switch which will start the gas flow.
4. As you trigger the torch switch you will notice that as the gas flow starts the needle on the gauge drops to a steady reading.
The reading while flowing is the value you want to read.
5. The gas flow should be set to ~20CFH while flowing. The CFH (Cubic Feet per Hour) scale is the inside scale in red on your
flow gauge. 20CFH is the most typical flow rate but it may need to be adjusted in some cases depending if there is a slight
breeze or some other instance where additional shielding gas is required to prevent porosity in the weld.
6. When finished welding remember to close the gas valve on the bottle.
Changing The Driver Roller
✓
The wire feed drive roller on the drive motor has 2 grooves, one for 0.023” (0.6mm) welding wire and another for 0.030” (0.8mm)
or 0.035” (0.9mm) welding wire. Your MIG175 comes with the drive roller pre installed for using 0.030” (0.8mm) wire. In the event
that 0.023” welding wire is to be used, the wire feed roller needs to be changed.
1. Turn off the welder and unplug the welder from power.
2. Unlock the Tensioner (Fig. 1I) by pulling it towards you.
FIG. I
3. Lift the Rocker Arm (Fig. 2I) up and rotate out of the way.
4. Remove the star knob (Fig. 3I) by loosening it by hand.
5. Slide the drive roller off the shaft.
6. Determine which size wire is going to be used and slide the
drive roller back onto the shaft by aligning the key on the shaft
with the keyway on the roller.

Operation
Welding Process
Your Eastwood MIG175 can be used to form a large number of different joints and welds all of which will require
practice and testing before using on an actual project piece. This following welding process is just a baseline to
get you started.
1. Refer to the ‘Suggested Settings’ chart which is located inside the side door of your Eastwood MIG175 as well
as below in the instruction manual. From the chart select your baseline starting point for the recommended
settings described in the chart.
2. Change the output polarity if necessary according to the welding wire’s specifications. This welder comes set
up to use Solid MIG wire, if using Flux Cored wire, the polarity will need to be changed.
3. Connect your ground clamp to the work pieces that are to be welded. Make sure the ground clamp contacts
are placed on a clean piece of metal free of paint, grease, rust, oils, etc. It is recommended to place your
ground clamp as close to the weld area as possible.
4. Assess your weld area and make sure the welding area is also cleaned of any paint, grease, rust, oils, etc.
5. Plug in the welder and switch to the ON position.
6. Open your gas valve on the bottle and adjust the flow rate if necessary.
7. Depress the torch trigger pointing the welding gun away from your body and then let go of the trigger and
cut the wire back to ~1/4” stick out length.
8. Wearing your welding helmet, gloves, and long sleeve shirt and pants, put the end of the wire sticking
out of the gun into the joint to be welded.
9. Position the welding gun so that it is perpendicular to the base metal with ~20° tilt back.
10.Depress the trigger to start the wire feed which starts the arc. NOTE: A push, perpendicular, or drag
technique can be used to weld the pieces together; the type used depends on the type of joint as well
as other influential conditions.
11.Once you depress the trigger and the arc has started, you will notice a molten puddle will form; this puddle
is the weld bead and will follow the motion of the welding torch. Watching the size of the puddle dictates how
fast you should be moving with the torch. If you burn through the material you are either moving to slow or you
need to make some setting adjustments to the welder settings. If you’re not penetrating the base metal you’re
either moving too fast or you need to make adjustments to the welder settings.
12.Release the trigger on the welding gun to stop the weld.
13.After finished welding, close the valve completely on the Shielding Gas Bottle.

Types of Weld Joints
1. Butt Weld is a joint between two pieces that are laying in
the same direction.
2. Corner Weld is a joint between two pieces that meet at
or near perpendicular at their edges.
3. Edge Weld is a joint between two pieces where the
edges are being joined.
4. Lap Weld is a joint between two overlapping pieces.
5. Tee Weld is a joint between two pieces where one is
perpendicular to the other.
6. Plug Weld is a joint which joins two overlapping pieces
by filling in a hole punched in the top piece.

Sheet Metal Welding Techniques
When welding sheet metal a different approach is usually taken to account for how thin the metal is and it’s susceptible to
warping it is. The technique most often used is called Stitch Welding and this process is described below:
1. Clean the metal to be welded of any paint, rust, oil, grease, dirt or any other contaminants that may be on the surface of the piece.
2. Secure the pieces to be welded in place using clamps. Be sure to leave a small gap between the two pieces of sheet
metal for the weld to flow into, this will result in a lower bead height which will require minimal finishing.
3. Consult the Suggested Settings Chart and set the Voltage and Wire Speed knobs appropriately.
4. Get some pieces of scrap metal of the same thickness and verify that the settings will work for the specific weld you
will be making.
5. Once the settings have been fine tuned tack weld your final pieces in places and remove the clamps if they are in the
way of the weld.
6. The Stitch Welding technique can now be utilized which is basically a series of tacks connecting together. To perform
the technique, trigger the gun to form a tack weld and then continue to trigger on and off the gun making a series of
connected tack welds following along the path of the weld joint. Continue the series of tacks for an inch or so and then
move to a different section of the weld and perform the process there. It is essential to keep moving around to spread
out the heat making sure not to get one section too hot and warp the metal.
7. Once the entire weld has been completed allow the metal to cool. If necessary follow up with a flap disc to grind the
weld bead flush.
Heavy Gauge Metal Welding Techniques
When welding sheet metal, a different approach is usually taken to account for how thin the metal is and it’s susceptible
to warping it is. The technique most often used is called Stitch Welding and this process is described below:
1. Clean the metal to be welded of any paint, rust, oil, grease, dirt or any other contaminants that may be on the surface
of the piece.
2. Secure the pieces to be welded in place using clamps. Be sure to leave a small gap between the two pieces of metal
for the weld to flow into, this will result in a lower bead height which will require minimal finishing.
3. Consult the Suggested Settings Chart and set the Voltage and Wire Speed knobs appropriately.
4. Get some pieces of scrap metal of the same thickness and verify that the settings will work for the specific weld you will be making.
5. Once the settings have been fine-tuned tack weld your final pieces in places and remove the clamps if they are in the
way of the weld.
6. When welding heavy gauge metal there are two basic approaches to creating the weld. The first is a continuous bead
with steady gun movement along the length of the joint. The second type of weld is a Stringer or Weave bead. This is
accomplished by moving the torch in a circular or zig zag pattern. Either of these techniques will create strong welds
but in some cases the Stringer or Weave type will create a more aesthetically appeasing weld bead.
7. Once the entire weld has been completed, allow the metal to cool. If necessary, follow up with a flap disc to grind the
weld bead flush.
Overload Protection
Your Eastwood MIG175 is equipped with a temperature controller as well as an overload breaker. These two protection devices will
protect your welder if the duty cycle is exceeded. If the output is exceeded, the internal breaker will trip and stop power supply to the
drive motor although the fan will still run to cool the unit.
If the breaker tripped resulting from an overload, the circuit breaker button on the rear of the welder will extend out. This circuit
breaker must be reset manually. Before resetting the circuit breaker button allow the welder to cool for a minimum of 15 minutes.
If there is no voltage output and the circuit breaker was not tripped, the internal thermal protector may have shut off the welder until
it cools to normal operating temperature. This is an automatic function and does not require the user to manually reset anything.
