Troubleshooting
No welding current
Mains switch is on, indicators on the power source are lit, shielding gas available
Cause:
Incorrect earth (ground) connection
Remedy:
Check the earth (ground) connection and clamp for correct polarity
Cause:
There is a break in the current cable in the welding torch
Remedy:
Replace the torch
No shielding gas
All other functions are OK
Cause:
The gas cylinder is empty
Remedy:
Change the gas cylinder
Cause:
Gas pressure regulator is faulty
Remedy:
Change the gas pressure regulator
Cause:
The gas hose is not connected, or is damaged or kinked
Remedy:
Connect/replace the gas hose, or straighten out kinks
Cause:
The welding torch is defective
Remedy:
Replace welding torch
Cause:
Gas solenoid valve is defective
Remedy:
Replace gas solenoid valve
Poor welding properties
Cause:
Incorrect welding parameters
Remedy:
Check the settings
Cause:
Poor connection to earth (ground)
Remedy:
Ensure good contact to workpiece
Cause:
Not enough shielding gas, or none at all
Remedy:
Check the pressure regulator, gas hose, gas solenoid valve and torch gas connection.
Cause:
Welding torch is leaking
Remedy:
Replace welding torch
Cause:
Contact tube is too large or worn out
Remedy:
Change the contact tube
Poor welding properties
Cause:
Wrong wire alloy or wrong wire diameter
Remedy:
Check the wirespool that has been inserted
Cause:
Wrong wire alloy or wrong wire diameter
Remedy:
Check weldability of the base material
Cause:
The shielding gas is not suitable for this wire alloy
Remedy:
Use the correct shielding gas
Cause:
Unfavourable welding conditions: shielding gas is contaminated (by moisture, air), inadequate gas
shielding (weld pool „boiling", draughts), contaminants in the workpiece (rust, paint, grease)
Remedy:
Optimise the welding conditions
Cause:
Welding spatter in the gas nozzle
Remedy:
Remove welding spatter
