WARNING!
Where fuses need to be changed, they must be replaced by fuses
of the same rating. No warranty claims will be accepted in respect of damage
caused by the use of too high a raiting of fuse!
Cause:
Welding torch is faulty
Remedy:
Replace the torch
Cause:
Gas solenoid valve is defective
Remedy:
Call after-sales service
7. No gas post-flow
Tungsten electrode discolours after end of welding
Cause:
Gas pre-flow time is set too short
Remedy:
Using internal program parameters, increase the gas post-flow time
(depends on welding amperage)
8. Poor arc ignition
Cause:
Gasvorströmzeit zu kurz eingestellt
Remedy:
Increase gas pre-flow time
Cause:
HF is too weak
Remedy:
See Pt.9 below
Cause:
Tungsten electrode is alloyed up, or pointed tip is damaged
Remedy:
Sharpen tip of tungsten electrode
Cause:
Tungsten electrode is underloaded
Remedy:
Use a suitable electrode for the amperage (also start-arc amperage) in
question
Cause:
Gas nozzle is dirty; HF jumps over the gas nozzle onto the workpiece
Remedy:
Use a new ceramic nozzle
Cause:
Gas nozzle is too small for the diameter of tungsten electrode used
Remedy:
Use a bigger gas nozzle
Cause:
Torch is damaged: torch body, protective hose etc. are faulty
Remedy:
Replace the damaged parts or change the torch
9. HF is too weak
Cause:
No shielding gas, or not enough
Remedy:
see Pt.6 above
10. Remote control unit does not work
(all other functions are OK)
Cause:
Remote control cable is not properly connected
Remedy:
Plug in the remote control cable the right way round
Cause:
Remote control unit or cable is faulty
Remedy:
Change the remote control unit or cable
Cause:
10-pole remote control socket is faulty
Remedy:
Change the remote control socket
