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
