Troubleshooting
9.2 TIG welding
Fault
Possible cause
Solution
The electrode melts when the arc is
skipped.
1. Electrode connected to output "+".
1. Connect electrode to output "-".
The weld bath is dirty.
1. Electrode contaminated by contact
with the weld bath or rod.
2. Gas contaminated with air.
1. New sharpen the electrode.
2. Check the gas pipes or replace the
cylinder.
The electrode melts or oxidizes when
the arc is skipped.
1. The gas does not reach the weld
bath.
2. Burner blocked by contamination.
3. Gas hose is cutting in.
4. Gas path contains impurities.
5. Gas valve closed.
6. Burner valve closed.
7. Electrode too small for the current
used.
1. Check for obstructions in the gas
pipes and check the cylinder.
2. Clean the burner.
3. Replace the gas hose.
4 Disconnect the gas supply from the
burner and increase the pressure
to blow the impurities out.
5 Open the gas valve.
6. Open the burner valve.
7. Reduce the welding current or re-
place the electrode with a larger
one.
Visibly bad welding.
1. Insufficient shielding gas. .
1. Raise the gas flow or check the
gas supply pipe.
Arc during TIG welding is unstable.
1. Tungsten electrode too large for
the welding current.
1. Select the correct electrode size.
The welding arc does not stabilize.
1. Grounding clamp not attached to
the workpiece or clamp not
connected to the correct poles.
2. Burner cable not connected.
3. Wrong gas flow, bottle empty or
valve closed.
1. Connect the earth clamp to the
workpiece to be welded or
connect the cables of the burner
and the earth to the correct
connections.
2. Connect the burner cable to con-
tact "-".
3. Correct the gas flow rate, change
the bottle or open the valve.
Arc does not jump smoothly over.
1. Tungsten electrode too large for
the welding current.
2. Tungsten electrode not adequate
for the work to be performed.
3. Gas flow too high.
4. Use of the wrong gas.
5. Bad contact between earth clamp
and workpiece.
1 Select the correct electrode size.
2. Select the correct electrode type.
3. Select the correct gas flow rate for
the work to be performed.
4. Select the correct gas type.
5. Make sure that there is good con-
tact between the grounding clamp
and the workpiece.
Fuse is triggered
1. High power consumption
1. Ensure that the house installation
is sufficiently dimensioned.
