1: 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
Inadequate gas flow
Check the gas is connected, check hoses, gas valve and torch are not restricted. Set
the gas flow between 10 - 15 l/min 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.
Tungsten melting back into the
nozzle on AC welding
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
2: 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 2 - 5mm
Touching the filler wire to the tung-
sten
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
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 10 - 15 l/min 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
4: Yellowish residue / smoke on the alumina nozzle & discoloured tungsten
Possible Reason
Suggested Remedy
Incorrect Gas
Use pure Argon gas
Inadequate gas flow
Set the gas flow between 10 - 15 l/min flow rate
Inadequate post flow gas
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 +
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
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.

6: HF present but no welding power
Possible Reason
Suggested Remedy
Incomplete welding circuit
Check earth lead is connected. Check all cable connections. If using a water cooled
torch check that the power cable is not separated.
No gas
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
