TIG Welding Trouble Shooting

The following addresses some of the common problems of DC TIG welding. In all cases of equipment malfunction, the manufacturer’s recommendations should be strictly adhered to and followed.

Tungsten Burning Away Quickly

Possible Reason	Suggested Remedy
Incorrect Gas	Check that pure Argon is being used
No gas	Check the gas cylinder contains gas and is connected and the torch gas valve is open
Inadequate gas flow	Check the gas is connected, check hoses, gas valve and torch are not restricted. Set the gas flow between 21-30cfh flow rate
Back cap not fitted correctly	Make sure the torch back cap is fitted so that the o-ring is inside the torch body
Torch connected to DC +	Connect the torch to the DC- output terminal
Incorrect tungsten being used	Check and change the tungsten type if necessary
Tungsten being oxidised after weld is finished	Keep shielding gas flowing 10–15 seconds after arc stoppage. 1 second for each 10 amps of weld current.

Contaminated Tungsten

Possible Reason	Suggested Remedy
Touching tungsten into the weld pool	Keep tungsten from contacting weld puddle. Raise the torch so that the tungsten is off of the work piece 1/8-1/4in
Touching the filler wire to the tungsten	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

Porosity - Poor Weld Appearance and Colour

Possible Reason	Suggested Remedy
Incorrect Gas	Check that pure Argon is being used
Inadequate gas flow / gas leaks	Check the gas is connected, check hoses, gas valve and torch are not restricted. Set the gas flow between 21-30cfh flow rate. Check hoses and fittings for holes, leaks etc.,
Moisture on the base metal	Remove all moisture from base metal before welding
Contaminated base metal	Remove materials like paint, grease, oil, and dirt, including mill scale from base metal
Contaminated filler wire	Remove all grease, oil, or moisture from filler metal.
Incorrect filler wire	Check the filler wire and change if necessary

Yellowish Residue / Smoke on the Alumina Nozzle & Discolored Tungsten

Possible Reason	Suggested Remedy
Incorrect Gas	Use pure Argon gas
Inadequate gas flow	Set the gas flow between 21-30cfh flow rate
Alumina gas nozzle too small for size of tungsten being used	Increase the size of the alumina gas nozzle

Unstable Arc During DC Welding

Possible Reason	Suggested Remedy
Torch connected to DC +	Connect the torch to the DC- output terminal
Contaminated base metal	Remove materials like paint, grease, oil, and dirt, including mill scale from base metal.
Tungsten is contaminated	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

Arc Wanders During DC Welding

Possible Reason	Suggested Remedy
Poor gas flow	Check and set the gas flow between 21-30cfh flow rate
Incorrect arc length	Lower torch so that the tungsten is off of the work piece 1/8-1/4in
Tungsten incorrect or in poor condition	Check that correct type of tungsten is being used. Remove 1/2in from the weld end of the tungsten and re sharpen the tungsten
Poorly prepared tungsten	Grind marks should run lengthwise with tungsten, not circular. Use proper grinding method and wheel.
Contaminated base metal	Remove contaminating materials like paint, grease, oil, and dirt, including mill scale from base metal.
Contaminated filler wire	Remove all grease, oil, or moisture from filler metal.
Incorrect filler wire	Check the filler wire and change if necessary

Arc Difficult To Start or Will Not Start DC Welding

Possible Reason	Suggested Remedy
Incorrect machine set up	Check machine set up is correct
No gas, incorrect gas flow	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 is contaminated	Remove 10mm of contaminated tungsten and re grind the tungsten
Incorrect tungsten size and or tungsten being used	Check and change the size and or the tungsten if required
Loose connection	Check all connectors and tighten
Earth clamp not connected to work	Connect the earth clamp directly to the work piece wherever possible

Important: We strongly recommend that you check for gas leakage prior to operation of your machine. We recommend that you close the cylinder valve when the machine is not in use. Coreone as authorized representative of the manufacturer will not be liable for costs incurred due to gas leakage.

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:

Connect the regulator and gas hose assembly and tighten all connectors and clamps.
Slowly open the cylinder valve.
Set the flow rate on the regulator to approximately 21-30cfh.
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 21-30cfh, close the cylinder valve and check after a minimum of 15 minutes.
If there is a gas loss then check all connectors and clamps for leakage by brushing or spraying with soapy water, bubbles will appear at the leakage point.
Tighten clamps or fittings to eliminate gas leakage.

Excessive Spatter

Possible Reason	Suggested Remedy
Wire feed speed set too high	Select lower wire feed speed
Voltage too high	Select a lower voltage setting
Wrong polarity set	select the correct polarity for the wire being used - see machine setup guide
Stick out too long	Bring the torch closer to the work
Contaminated base metal	Remove materials like paint, grease, oil, and dirt, including mill scale from base metal
Contaminated mig wire	Use clean dry rust free wire. Do not lubricate the wire with oil, grease etc
Inadequate gas flow or too much gas flow	Check the gas is connected, check hoses, gas valve and torch are not restricted. Set the gas flow between 21-30cfh flow rate. Check hoses and fittings for holes, leaks etc Protect the welding zone from wind and drafts

Porosity - Small Cavities or Holes Resulting from Gas Pockets in Weld Metal.

Possible Reason	Suggested Remedy
Wrong gas	Check that the correct gas is being used
Inadequate gas flow or too much gas flow	Check the gas is connected, check hoses, gas valve and torch are not restricted. Set the gas flow between 21-30cfh flow rate. Check hoses and fittings for holes, leaks etc. Protect the welding zone from wind and drafts

Wire Stubbing During Welding

Possible Reason	Suggested Remedy
Holding the torch too far away	Bring the torch closer to the work and maintain stick out of 5-10mm
Welding voltage set too low	Increase the voltage
Wire Speed set too high	Decrease the wire feed speed

Lack of Fusion − Failure of Weld Metal to Fuse Completely with Base Metal or a Proceeding Weld Bead.

Possible Reason	Suggested Remedy
Contaminated base metal	Remove materials like paint, grease, oil, and dirt, including mill scale from base metal
Not enough heat input	Select a higher voltage range and /or adjust the wire speed to suit
Improper welding technique	Keep the arc at the leading edge of the weld pool. Gun angle to work should be between 5 & 15° Direct the arc at the weld joint Adjust work angle or widen groove to access bottom during welding Momentarily hold arc on side walls if using weaving technique

Excessive Penetration − Weld Metal Melting Through Base Metal

Possible Reason	Suggested Remedy
Too much heat	Select a lower voltage range and /or adjust the wire speed to suit. Increase travel speed

Lack of Penetration − Shallow Fusion Between Weld Metal and Base Metal

Possible Reason	Suggested Remedy
Poor in incorrect joint preparation	Material too thick. Joint preparation and design needs to allow access to bottom of groove while maintaining proper welding wire extension and arc characteristics. Keep the arc at the leading edge of the weld pool and maintain the gun angle at 5 & 15° keeping the stick out between 1/8-1/4in
Not enough heat input	Select a higher voltage range and /or adjust the wire speed to suit. Reduce travel speed
Contaminated base metal	Remove materials like paint, grease, oil, and dirt, including mill scale from base metal.

Wrong polarity selected	Select the correct polarity for the wire being used - see machine setup guide
Incorrect wire speed setting	Adjust the wire feed speed
Voltage setting incorrect	Adjust the voltage setting
Mig torch lead too long	Small diameter wires and soft wires like aluminium don’t feed well through long torch leads - replace the torch with a lesser length torch
Mig torch lead kinked or too sharp angle being held	Remove the kink, reduce the angle or bend
Contact tip worn, wrong size, wrong type	Replace the tip with correct size and type
Liner worn or clogged (the most com - mon causes of bad feeding)	Try to clear the liner by blowing out with compressed air as a temporary cure, it is recommended to replace the liner
Wrong size liner	Install the correct size liner
Blocked or worn inlet guide tube	Clear or replace the inlet guide tube
Wire misaligned in drive roller groove	Locate the wire into the groove of the drive roller
Incorrect drive roller size	Fit the correct size drive roller eg; .030in wire requires .030in drive roller
Wrong type of drive roller selected	Fit the correct type roller (e.g. knurled rollers needed for flux cored wires)
Worn drive rollers	Replace the drive rollers
Drive roller pressure too high	Can flatten the wire electrode causing it to lodge in the contact tip - reduce the drive roller pressure
Too much tension on wire spool hub	Reduce the spool hub brake tension
Wire crossed over on the spool or tangled	Remove the spool untangle the wire or replace the wire
Contaminated mig wire	Use clean dry rust free wire. Do not lubricate the wire with oil, grease etc
