SAFETY
Welding and cutting equipment can be dangerous to both the operator and people in or near the surrounding working area, if the equipment is not correctly operated. Equipment must only be used under the strict and comprehensive observance of all relevant safety regulations.
Read and understand this instruction manual carefully before the installation and operation of this equipment.
Machine Operating Safety
• Do not switch the function modes while the machine is operating. Switching of the function modes during
welding can damage the machine. Damage caused in this manner will not be covered under warranty.
• Disconnect the electrode-holder cable from the machine before switching on the machine, to avoid arcing
should the electrode be in contact with the work piece.
• Operators should be trained and or qualified.
Electric shock: It can kill. Touching live electrical parts can cause fatal shocks or severe burns. The electrode and work circuit is electrically live whenever the output is on. The input power circuit and internal machine circuits are also live when power is on. In Mig/Mag welding, the wire, drive rollers, wire feed housing, and all metal parts touching the welding wire are electrically live. Incorrectly installed or improperly grounded equipment is dangerous.
• Connect the primary input cable according to Australian and New Zealand standards and regulations.
• Avoid all contact with live electrical parts of the welding circuit, electrodes and wires with bare hands.
The operator must wear dry welding gloves while he/she performs the welding task.
• The operator should keep the work piece insulated from himself/herself.
• Keep cords dry, free of oil and grease, and protected from hot metal and sparks.
• Frequently inspect input power cable for wear and tear, replace the cable immediately if damaged,
bare wiring is dangerous and can kill.
• Do not use damaged, under sized, or badly joined cables.
• Do not drape cables over your body.
Fumes and gases are dangerous. Smoke and gas generated whilst welding or cutting can be harmful to people’s health. Welding produces fumes and gases. Breathing these fumes and gases can be hazardous to your health.
• Do not breathe the smoke and gas generated whilst welding or cutting, keep your head out of the fumes
• Keep the working area well ventilated, use fume extraction or ventilation to remove welding fumes and
gases.
• In confined or heavy fume environments always wear an approved air-supplied respirator.
Welding fumes and gases can displace air and lower the oxygen level causing injury or death. Be sure the
breathing air is safe.
• Do not weld in locations near de-greasing, cleaning, or spraying operations. The heat and rays of the arc
can react with vapours to form highly toxic and irritating gases.
• Materials such as galvanized, lead, or cadmium plated steel, containing elements that can give off toxic
fumes when welded. Do not weld these materials unless the area is very well ventilated, and or wearing
an air supplied respirator.
Arc rays: harmful to people’s eyes and skin. Arc rays from the welding process produce intense visible and invisible ultraviolet and infrared rays that can burn eyes and skin.
• Always wear a welding helmet with correct shade of filter lens and suitable protective clothing including
welding gloves whilst the welding operation is performed.
• Measures should be taken to protect people in or near the surrounding working area. Use protective
screens or barriers to protect others from flash,glare and sparks; warn others not to watch the arc.
4
Fire hazard. Welding on closed containers, such as tanks,drums, or pipes, can cause them to explode. Flying sparks from the welding arc, hot work piece, and hot equipment can cause fires and burns. Accidental contact of electrode to metal objects can cause sparks, explosion, overheating, or fire. Check and be sure the area is safe before doing any welding.
• The welding sparks may cause fire, therefore remove any flammable materials away from the working
area, at least 12m from the welding arc. Cover flammable materials and containers with approved covers
if unable to be moved from the welding area.
• Do not weld on closed containers such as tanks, drums, or pipes, unless they are properly prepared
according to the required Safety Standards to insure that flammable or toxic vapors and substances are
totally removed, these can cause an explosion even though the vessel has been “cleaned”.
Vent hollow castings or containers before heating, cutting or welding. They may explode.
• Do not weld where the atmosphere may contain flammable dust, gas, or liquid vapours (such as petrol)
• Have a fire extinguisher nearby and know how to use it. Be alert that welding sparks and hot materials
from welding can easily go through small cracks and openings to adjacent areas. Be aware that welding
on a ceiling, floor, bulkhead, or partition can cause fire on the hidden side.
Gas Cylinders. Shielding gas cylinders contain gas under high pressure. If damaged, a cylinder can explode. Because gas cylinders are normally part of the welding process, be sure to treat them carefully. CYLINDERS can explode if damaged.
• Protect gas cylinders from excessive heat, mechanical shocks, physical damage, slag, open flames,
sparks, and arcs.
• Insure cylinders are held secure and upright to prevent tipping or falling over.
• Never allow the welding electrode or earth clamp to touch the gas cylinder, do not drape welding cables
over the cylinder.
• Never weld on a pressurised gas cylinder, it will explode and kill you.
• Open the cylinder valve slowly and turn your face away from the cylinder outlet valve and gas regulator.
Gas build up. The build up of gas can causes a toxic environment, deplete the oxygen content in the air resulting in death or injury. Many gases use in welding are invisible and odourless.
• Shut off shielding gas supply when not in use.
• Always ventilate confined spaces or use approved air-supplied respirator.
Electronic magnetic fields. MAGNETIC FIELDS can affect Implanted Medical Devices.
• Wearers of Pacemakers and other Implanted Medical Devices should keep away.
• Implanted Medical Device wearers should consult their doctor and the device manufacturer before going
near any electric welding, cutting or heating operation.
Noise can damage hearing. Noise from some processes or equipment can damage hearing.
Wear approved ear protection if noise level is high.
Hot parts. Items being welded generate and hold high heat and can cause severe burns.
Do not touch hot parts with bare hands. Allow a cooling period before working on the welding gun. Use insulated welding gloves and clothing to handle hot parts and prevent burns.

ARC FORCE - What is the Arc Force Control and what does it do?
The arc force control lets you adjust the force of the arc from a soft buttery arc to a more penetrating, digging type of arc.
Arc voltage drops as the arc gets tighter and can cause the electrode to stick/short circuit to the work piece.
When you set the arc force high the machine senses the drop in voltage. As the rod is about to stick the machine compensates by increasing the arc voltage. This boost in arc voltage/current blasts away base metal and electrode to prevent the electrode from welding itself to the work piece. Higher Arc Force is more suited to Cellulose and Low Hydrogen type electrodes where a forceful arc characteristic is preferred to maintain the arc and better control penetration. Lower Arc Force is better suited to Hardfacing and
Cast Iron electrodes where a soft buttery arc is preferred to prevent the electrode material diluting too much with the base metal.

MMA (Manual Metal Arc) Welding
One of the most common types of arc welding is manual metal arc welding (MMA) or stick welding. An electric current is used to strike an arc between the base material and a consumable electrode rod or ‘stick’. The electrode rod is made of a material that is compatible with the base material being welded and is covered with a flux that gives off gaseous vapours that serve as a shielding gas and providing a layer of slag, both of which protect the weld area from atmospheric contamination. The electrode core itself acts as filler material the residue from the flux that forms a slag covering over the weld metal must be chipped away after welding.

Weld pool
• The arc is initiated by momentarily touching the electrode to the base metal.
• The heat of the arc melts the surface of the base metal to form a molten pool
at the end of the electrode.
• The melted electrode metal is transferred across the arc into the molten pool
and becomes the deposited weld metal.
• The deposit is covered and protected by a slag which comes from the
electrode coating.
• The arc and the immediate area are enveloped by an atmosphere of
protective gas
Manual metal arc ( stick) electrodes have a solid metal wire core and a flux coating. These electrodes are identified by the wire diameter and by a series of letters and numbers. The letters and numbers identify the metal alloy and the intended use of the electrode.
The Metal Wire Core works as conductor of the current that maintains the arc.
The core wire melts and is deposited into the welding pool.
The covering on a shielded metal arc welding electrode is called Flux.
The flux on the electrode performs many different functions.
These include:
● producing a protective gas around the weld area
● providing fluxing elements and deoxidizers
● creating a protective slag coating over the weld as it cools
● establishing arc characteristics
● adding alloying elements.
Covered electrodes serve many purposes in addition to adding filler metal to the molten pool. These additional functions are provided mainly by the covering on the electrode.

MMA (Stick) Welding Fundamentals
Electrode Selection
As a general rule, the selection of an electrode is straight forward,in that it is only a matter of selecting an electrode of similar composition to the parent metal. However, for some metals there is a choice of several electrodes, each of which has particular properties to suit specific classes of work. It is recommend to consult your welding supplier for the correct selection of electrode.
Electrode Size
Average Thickness Maximum Recommended of Material Electrode Diameter
1.0 - 2.0mm
2.0 - 5.0mm
5.0 - 8.0mm
8.0 - > mm
2.5mm
3.2mm
4.0mm
5.0mm
The size of the electrode generally depends on the thickness of the section being welded, and the thicker the section the larger the electrode required. The table gives the maximum size of electrodes that maybe used for various thicknesses of section base on using a general purpose type 6013 electrode.

165 - 260
Correct current selection for a particular job is an important factor in arc welding. With the current set too low, difficulty is experienced in striking and maintaining a stable arc. The electrode tends to stick to the work, penetration is poor and beads with a distinct rounded profile will be deposited. Too high current is accompanied by overheating of the electrode resulting undercut and burning through of the base metal and producing excessive spatter. Normal current for a particular job may be considered as the maximum, which can be used without burning through the work, over-heating the electrode or producing a rough spattered surface.
The table shows current ranges generally recommended for a general purpose type 6013 electrode.
Arc Length
To strike the arc, the electrode should be gently scraped on the work until the arc is established. There is a simple rule for the proper arc length; it should be the shortest arc that gives a good surface to the weld. An arc too long reduces penetration, produces spatter and gives a rough surface finish to the weld. An excessively short arc will cause sticking of the electrode and result in poor quality welds. General rule of thumb for down hand welding is to have an arc length no greater than the diameter of the core wire.
Electrode Angle
The angle that the electrode makes with the work is important to ensure a smooth, even transfer of metal.
When welding in down hand, fillet, horizontal or overhead the angle of the electrode is generally between 5 and 15 degrees towards the direction of travel. When vertical up welding the angle of the electrode should be between 80 and 90 degrees to the work piece.
Travel Speed
The electrode should be moved along in the direction of the joint being welded at a speed that will give the size of run required. At the same time, the electrode is fed downwards to keep the correct arc length at all times. Excessive travel speeds lead to poor fusion, lack of penetration etc, while too slow a rate of travel will frequently lead to arc instability,slag inclusions and poor mechanical properties.
Material and Joint Preparation
The material to be welded should be clean and free of any moisture, paint, oil, grease, mill scale, rust or any other material that will hinder the arc and contaminate the weld material. Joint preparation will depend on the method used include sawing, punching, shearing, machining, flame cutting and others. In all cases edges should be clean and free of any contaminates. The type of joint will be determined by the chosen application.

DC HF TIG Welding Standard Operation: Razor 2OO TIG-MMA
HF (high frequency) ignition allows the arc to be started in TIG welding without touching the tungsten to the work piece. By pressing the torch switch the machine will activate the gas flow and the HF ignition resulting in the arc igniting across the gap between the tungsten electrode and the work piece. The distance between the electrode and the work piece can be up to 5mm. This arc ignition method prevents tungsten inclusion in the work piece, promotes longer tungsten life and offers better operator control over the starting and stopping the arc.
(1) Assemble the front end torch parts use the correct size and type of tungsten electrode for the job, the tungsten electrode requires a sharpened point for DC welding.

DC TIG Welding
70%
30% power source
The DC power source uses what is known as DC (direct current) in which the main electrical component known as electrons flow in only one direction from the negative pole
(terminal) to the positive pole (terminal). In the DC electrical circuit there is an electrical principle at work which should always be taken into account when using any DC circuit.
With a DC circuit 70% of the energy (heat) is always on the positive side. This needs to be understood because it determines what terminal the TIG torch will be connected to
(this rule applies to all the other forms of DC welding as well ).
argon gas nozzle
DC TIG welding is a process in which an arc is struck between a
TUNGSTEN electrode and the metal work piece. The weld area is shielded by an inert gas flow to prevent contamination of the tungsten, molten pool and weld area.
When the TIG arc is struck the inert gas is ionized and superheated changing it’s molecular structure which converts it into a plasma stream. This plasma stream flowing between the tungsten and the work piece is the TIG arc and can be as hot as 19,000°C. It is a very pure and concentrated arc which provides the controlled melting of most metals into a weld pool. TIG welding offers the user the greatest amount of flexibility to weld the widest range of material and thickness and types. DC TIG welding is also the cleanest weld with no sparks or spatter.
The intensity of the arc is proportional to the current that flows from the tungsten. The welder regulates the welding current to adjust the power of the arc. Typically thin material requires a less powerful arc with less heat to melt the material so less current (amps) is required, thicker material requires a more powerful arc with more heat so more current
(amps) are necessary to melt the material.
HF ARC IGNITION for TIG (tungsten inert gas) Welding
HF (high frequency) ignition allows the arc to be started in TIG welding without touching the tungsten to the work piece. By pressing the torch switch the machine will activate the gas flow and introduce the HF (high frequency) (high voltage) spark, this “ionizes” the air gap making it conductive allowing an arc to be created without touching the tungsten to the work piece. The gas molecules are superheated by the arc creating a stream of super heated gas that changes the molecular structure into producing a plasma stream. This plasma stream provides heat and energy that allows us to melt and fuse metals in an inert gas shielded environment know as TIG (tungsten inert gas) welding.

DC Pulse TIG Welding
Pulse TIG welding is when the current output (amperage) changes between high and low current.
Electronics within the welding machine create the pulse cycle. Welding is done during the high-amperage interval (this high amperage is referred to as peak current). During the low amperage period, the arc is maintained but the current output of the arc is reduced (this low amperage is referred to as base current).
During pulse welding the weld pool cools during the low amperage period. This allows a lower overall heat input into the base metal. It allows for controlled heating and cooling periods during welding providing better control of heat input, weld penetration, operator control and weld appearance.
There are 4 variables within the pulse cycle:
Peak Current - Base Current - Pulse Frequency - Pulse Width
Setting and manipulation of these variables will determine the nature of the weld current output and is at the discretion of the operator.
Peak Current is the main welding current (amps) set to melt the material being welded and works much the same as setting maximum amperage values for regular DC TIG: as a guide use 30-40 amps for every 1mm of material thickness.
Base Current is the set level of background current (amps) which cools the weld puddle and affects overall heat input. Background Amps is a percentage of peak amperage. As a rule, use enough background current to reduce the weld pool to about half its normal size while still keeping the weld pool fluid. As a guide start by setting the background amperage at 20 to 30 percent of peak amperage.
Pulse Frequency is the control of the amount of times per second (Hz) that the welding current switches from Peak Current to Base Current. DC Pulse TIG frequency generally ranges from 20 to 300 HZ depending on the job application. Control of the pulse frequency also determines the appearance of the weld.
Pulse Width is the control of the percentage of time during one pulsing cycle the power source spends at the peak current (main amperage). Example is with the Pulse Width set at 80 percent and a rate of 1 pulse per second (PPS), the machine will spend 80% of the pulse at peak amperage and 20% at the base current. Increasing the pulse width percentage adds more heat to the job, while decreasing pulse width percentage reduces heat

DC Pulse TIG welding allows faster welding speeds with better control of the heat input to the job, reducing the heat input minimising distortion and warping of the work and is of particular advantage in the welding of thin stainless steel and carbon steel applications. The high pulse frequency capability of the advanced inverter agitates the weld puddle and allows you to move quickly without transferring too much heat to the surrounding metal. Pulsing also constricts and focuses the arc thus increasing arc stability, penetration and travel speeds. high frequency pulsing no pulse

TIG Welding Fusion Technique
Manual TIG welding is often considered the most difficult of all the welding processes.
Because the welder must maintain a short arc length, great care and skill are required to prevent contact between the electrode and the workpiece. Similar to Oxygen Acetylene torch welding, TIG welding normally requires two hands and in most instances requires the welder to manually feed a filler wire into the weld pool with one hand while manipulating the welding torch in the other. However, some welds combining thin materials can be accomplished without filler metal like edge, corner, and butt joints.
This is known as Fusion welding where the edges of the metal pieces are melted together using only the heat and arc force generated by the TIG arc. Once the arc is started the torch tungsten is held in place until a weld pool is created, a circular movement of the tungsten will assist is creating a weld pool of the desired size. Once the weld pool is established tilt the torch at about a 75
° angle and move smoothly and evenly along the joint while fusing the materials together.

TIG Welding with Filler Wire Technique
It is necessary in many situations with TIG welding to add a filler wire into the weld pool to build up weld reinforcement and create a strong weld. Once the arc is started the torch tungsten is held in place until a weld pool is created, a circular movement of the tungsten will assist is creating a weld pool of the desired size. Once the weld pool is established tilt the torch at about a 75
° angle and move smoothly and evenly along the joint. The filler metal is introduced to the leading edge of the weld pool. The filler wire is usually held at about a 15° angle and fed into the leading edge of the molten pool, the arc will melt the filler wire into the weld pool as the torch is moved forward. Also a dabbing technique can be used to control the amount of filler wire added, the wire is fed into the molten pool and retracted in a repeating sequence as the torch is moved slowly and evenly forward. It is important during the welding to keep the molten end of the filler wire inside the gas shield as this protects the end of the wire from being oxidised and contaminating the weld pool.

Tungsten Electrodes
Tungsten is a rare metallic element used for manufacturing TIG welding electrodes. The TIG process relies on tungsten’s hardness and high-temperature resistance to carry the welding current to the arc. Tungsten has the highest melting point of any metal, 3,410 degrees Celsius.
Tungsten electrodes are nonconsumable and come in a variety of sizes, they are made from pure tungsten or an alloy of tungsten and other rare earth elements. Choosing the correct tungsten depends on the material being welded, the amount of amps required and whether you are using AC or DC welding current.
Tungsten electrodes are colour-coded at the end for easy identification.
Below are the most commonly used tungsten electrodes found in the New Zealand and Australian market.
Thoriated
Thoriated tungsten electrodes (AWS classification EWTh-2) contain a minimum of 97.30 percent tungsten and 1.70 to 2.20 percent thorium and are called 2 percent thoriated. They are the most commonly used electrodes today and are preferred for their longevity and ease of use. Thorium increases the electron emission qualities of the electrode, which improves arc starts and allows for a higher current-carrying capacity. This electrode operates far below its melting temperature, which results in a considerably lower rate of consumption and eliminates arc wandering for greater stability. Compared with other electrodes, thoriated electrodes deposit less tungsten into the weld puddle, so they cause less weld contamination.
Thorium however is a low-level radioactive hazard and many users have switched to other alternatives. Regarding the radioactivity, thorium is an alpha emitter but when it is enclosed in a tungsten matrix the risks are negligible.
Thus holding a stick of Thoriated tungsten in your hand should not pose a great threat unless a welder has open cuts on their skin. Thoriated tungsten should not get in contact with open cuts or wounds. The more significant danger to welders can occur when thorium oxide gets into the lungs. This can happen from the exposure to vapours during welding or from ingestion of material/dust in the grinding of the tungsten. Follow the manufacturer’s warnings, instructions, and the Material Safety Data Sheet (MSDS) for its use.
Ceriated (Color Code: Orange)
Ceriated tungsten electrodes (AWS classification EWCe-2) contain a minimum of 97.30 percent tungsten and 1.80 to
2.20 percent cerium and are referred to as 2 percent ceriated. Ceriated tungstens perform best in DC welding at low current settings. They have excellent arc starts at low amperages and become popular in such applications as orbital tube welding, thin sheet metal work. They are best used to weld carbon steel, stainless steel, nickel alloys, and titanium, and in some cases it can replace 2 percent thoriated electrodes. Ceriated tungsten is best suited for lower amperages it should last longer than Thoriated tungsten higher amperage applications are best left to Thoriated or
Lanthanated tungsten.
Lanthanated (Color Code: Gold)
Lanthanated tungsten electrodes (AWS classification EWLa-1.5) contain a minimum of 97.80 percent tungsten and
1.30 percent to 1.70 percent lanthanum, and are known as 1.5 percent lanthanated. These electrodes have excellent arc starting, a low burn off rate, good arc stability, and excellent re-ignition characteristics. Lanthanated tungstens also share the conductivity characteristics of 2 percent thoriated tungsten. Lanthanated tungsten electrodes are ideal if you want to optimise your welding capabilities. They work well on AC or DC electrode negative with a pointed end, or they can be balled for use with AC sine wave power sources. Lanthanated tungsten maintains a sharpened point well, which is an advantage for welding steel and stainless steel on DC or AC from square wave power sources.
Zirconiated (Color Code: White)
Zirconiated tungsten electrodes (AWS classification EWZr-1) contain a minimum of 99.10 percent tungsten and 0.15 to 0.40 percent zirconium. Most commonly used for AC welding Zirconiated tungsten produces a very stable arc and is resistant to tungsten spitting. It is ideal for AC welding because it retains a balled tip and has a high resistance to contamination. Its current-carrying capacity is equal to or greater than that of thoriated tungsten. Zirconiated tungsten is not recommended for DC welding.

Tungsten Preparation
Always use DIAMOND wheels when grinding and cutting. While tungsten is a very hard material, the surface of a diamond wheel is harder, and this makes for smooth grinding. Grinding without diamond wheels, such as aluminium oxide wheels, can lead to jagged edges, imperfections, or poor surface finishes not visible to the eye that will contribute to weld inconsistency and weld defects.
Always ensure to grind the tungsten in a longitudinal direction on the grinding wheel. Tungsten electrodes are manufactured with the molecular structure of the grain running lengthwise and thus grinding crosswise is “grinding against the grain.” If electrodes are ground crosswise, the electrons have to jump across the grinding marks and the arc can start before the tip and wander. Grinding longitudinally with the grain, the electrons flow steadily and easily to the end of the tungsten tip. The arc starts straight and remains narrow, concentrated, and stable. grind longitudinal on the grinding wheel don’t grind across the grinding whee l
Electrode Tip/Flat
The shape of the tungsten electrode tip is an important process variable in precision arc welding. A good selection of tip/flat size will balance the need for several advantages. The bigger the flat, the more likely arc wander will occur and the more difficult it will be to arc start. However, increasing the flat to the maximum level that still allows arc start and eliminates arc wonder will improve the weld penetration and increase the electrode life. Some welders still grind electrodes to a sharp point, which makes arc starting easier. However, they risk decreased welding performance from melting at the tip and the possibility of the point falling off into the weld pool.

Electrode Included Angle/Taper - DC Welding
Tungsten electrodes for DC welding should be ground longitudinally and concentrically with diamond wheels to a specific included angle in conjunction with the tip/flat preparation. Different angles produce different arc shapes and offer different weld penetration capabilities. In general, blunter electrodes that have a larger included angle provide the following benefits:
• Last Longer
• Have better weld penetration
• Have a narrower arc shape
• Can handle more amperage without eroding. flat spot diameter
Sharper electrodes with smaller included angle provide:
• Offer less arc weld
• Have a wider arc
• Have a more consistent arc included angle
The included angle determines weld bead shape and size. Generally, as the included angle increases, penetration increases and bead width decreases.

ATTENTION! - CHECK FOR GAS LEAKS
At initial set up and at regular intervals we recommend to check for gas leakage.
Recommended procedure is as follows:
1. Connect the regulator and gas hose assembly and tighten all connectors and clamps.
2. Slowly open the cylinder valve.
3. Set the flow rate on the regulator to approximately 8-10 l/min.
4. Close the cylinder valve and pay attention to the needle indicator of the contents pressure
gauge on the regulator, if the needle drops away towards zero there is a gas leak.
Sometimes a gas leak can be slow and to identify it will require leaving the gas pressure in the
regulator and line for an extended time period. In this situation it is recommended to open the
cylinder valve, set the flow rate to 8-10 l/min, close the cylinder valve and check after a
minimum of 15 minutes.
5. If there is a gas loss then check all connectors and clamps for leakage by brushing or spraying

TIG WELDING TROUBLE SHOOTING
The following chart addresses some of the common problems of TIG welding. In all cases of equipment malfunction, the manufacturer’s recommendations should be strictly adhered to and followed.
1: Tungsten burning away quickly
Possible Reason Suggested Remedy
Incorrect Gas
No gas
Inadequate gas flow
Back cap not fitted correctly
Torch connected to DC +
Incorrect tungsten being used
Tungsten being oxidised after weld is finished
Tungsten melting back into the nozzle on AC welding
2: Contaminated tungsten
Possible Reason
Check that pure Argon is being used
Check the gas cylinder contains gas and is connected
Check the gas is connected, check hoses, gas valve and torch are not restricted. Set the gas flow between 8-12 l/min flow rate
Make sure the torch back cap is fitted so that the o-ring is inside the torch body
Connect the torch to the DC- output terminal
Check and change the tungsten type if necessary
Keep shielding gas flowing 10–15 seconds after arc stoppage. 1 second for each 10 amps of weld current.
Check that correct type of tungsten is being used. Check the balance control is not set too high on the balance - reduce to a lower setting
Suggested Remedy
Touching tungsten into the weld pool
Touching the filler wire to the tungsten
Keep tungsten from contacting weld puddle. Raise the torch so that the tungsten is off of the work piece 2 - 5mm
Keep the filler wire from touching the tungsten during welding, feed the filler wire into the leading edge of the weld pool in front of the tungsten
Tungsten melting into the weld pool Check that correct type of tungsten is being used. Too much current for the tungsten size so reduce the amps or change to a larger tungsten
3: Porosity - poor weld appearance and colour
Possible Reason Suggested Remedy
Incorrect Gas
Inadequate gas flow / gas leaks
Moisture on the base metal
Contaminated base metal
Contaminated filler wire
Check that pure Argon is being used
Check the gas is connected, check hoses, gas valve and torch are not restricted. Set the gas flow between 8-12 l/min flow rate. Check hoses and fittings for holes, leaks etc.,
Remove all moisture from base metal before welding
Remove materials like paint, grease, oil, and dirt, including mill scale from base metal
Remove all grease, oil, or moisture from filler metal.
Incorrect filler wire Check the filler wire and change if necessary
4: Yellowish residue / smoke on the alumina nozzle & discoloured tungsten
Possible Reason Suggested Remedy
Incorrect Gas
Inadequate gas flow
Inadequate post flow gas
Use pure Argon gas
Set the gas flow between 8-12 l/min flow rate
Increase the post flow gas time
Alumina gas nozzle too small for size of tungsten being used
Increase the size of the alumina gas nozzle
5: Unstable Arc during DC welding
Possible Reason Suggested Remedy
Torch connected to DC +
Contaminated base metal
Tungsten is contaminated
Connect the torch to the DC- output terminal
Remove materials like paint, grease, oil, and dirt, including mill scale from base metal.
Remove 10mm of contaminated tungsten and re grind the tungsten
Arc length too long Lower torch so that the tungsten is off of the work piece 2 - 5mm
6: HF present but no welding power
Possible Reason Suggested Remedy
Incomplete welding circuit
No gas
Check earth lead is connected. Check all cable connections. If using a water cooled torch check that the power cable is not separated.
Check the gas is connected and cylinder valve open, check hoses, gas valve and torch are not restricted. Set the gas flow between 10 - 15 l/min flow rate
Tungsten melting into the weld pool Check that correct type of tungsten is being used. Too much current for the tungsten size so reduce the amps or change to a larger tungsten
29
continued- TIG WELDING TROUBLE SHOOTING
7: Arc wanders during DC welding
Possible Reason Suggested Remedy
Poor gas flow
Incorrect arc length
Tungsten incorrect or in poor condition
Poorly prepared tungsten
Check and set the gas flow between 10 - 15 l/min flow rate
Lower torch so that the tungsten is off of the work piece 2 - 5mm
Check that correct type of tungsten is being used. Remove 10mm from the weld end of the tungsten and re sharpen the tungsten
Grind marks should run lengthwise with tungsten, not circular. Use proper grinding method and wheel.
Contaminated base metal
Contaminated filler wire
Remove contaminating materials like paint, grease, oil, and dirt, including mill scale from base metal.
Remove all grease, oil, or moisture from filler metal.
Incorrect filler wire Check the filler wire and change if necessary
8: Arc difficult to start or will not start DC welding
Possible Reason Suggested Remedy
Incorrect machine set up
No gas, incorrect gas flow
Tungsten is contaminated
Incorrect tungsten size and or tungsten being used
Loose connection
Earth clamp not connected to work
Loss of high frequency
Check machine set up is correct
Check the gas is connected and cylinder valve open, check hoses, gas valve and torch are not restricted. Set the gas flow between 10 - 15 l/min flow rate
Remove 10mm of contaminated tungsten and re grind the tungsten
Check and change the size and or the tungsten if required
Check all connectors and tighten
Connect the earth clamp directly to the work piece wherever possible
Check torch and cables for cracked insulation or bad connections. Check spark gaps and adjust if necessary
30
MMA (Stick) WELDING TROUBLE SHOOTING
The following chart addresses some of the common problems of MMA welding. In all cases of equipment malfunction, the manufacturer’s recommendations should be strictly adhered to and followed.
1: No arc
Possible Reason
Incomplete welding circuit
Wrong mode selected
No power supply
Check earth lead is connected. Check all cable connections.
Check the MMA selector switch is selected
Check that the machine is switched on and has a power supply
2: Porosity − small cavities or holes resulting from gas pockets in weld metal.
Possible Reason Suggested Remedy
Arc length too long
Work piece dirty, contaminated or moisture
Damp electrodes
3: Excessive Spatter
Possible Reason
Suggested Remedy
Shorten the arc length
Remove moisture and materials like paint, grease, oil, and dirt, including mill scale from base metal
Use only dry electrodes
Suggested Remedy
Amperage too high Decrease the amperage or choose a larger electrode
Arc length too long
3: Weld sits on top, lack of fusion
Shorten the arc length
Possible Reason Suggested Remedy
Insufficient heat input
Work piece dirty, contaminated or moisture
Poor welding technique
4: Lack of penetration
Possible Reason
Increase the amperage or choose a larger electrode
Remove moisture and materials like paint, grease, oil, and dirt, including mill scale from base metal
Use the correct welding technique or seek assistance for the correct technique
