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 RATING OF FUSE!
Error n°: Fault diagnosis:
Err 01 Overtemperature indicator: t - P / t - S é see Pt. 4
Err 02 Thermosensor short circuit
Err 03 Thermosensor break
Err 04 Not activated at present
Err 05 Hall compensating error
Err 06 Current command value compensating error
Err 07 RAM accessing error
Err 08 EEprom accessing error
Err 09 secondary overvoltage fault
é
see Pt. 5
Err 10 Not activated at present
Using internal program parameters, in-
crease the gas post-flow time (depends
on welding amperage - see p. 12 Pt. 2) 9. NO GAS POST-FLOW
Tungsten electrode discolours after
end of welding
Gas post-flow time is set too short
10. POOR ARC IGNITION
Shorten the tungsten electrode and form
a new dome at the tip (see p. 11, Pt. )
Tungsten electrode is underloaded (with
especially negative consequences in AC) Use a suitable electrode for the ampera-
ge (also start-arc amperage) in question
Torch is damaged:
insulated torch components such as torch
body, protective hose etc. are faulty Replace the damaged parts or change
the torch
Ignition device (ZMW 20) is faulty Call after-sales service
No shielding gas, or not enough
[TC 1 MC AC (DC) module]
See Pt. 8 above
11. HF IS TOO WEAK
Fuse F1 on TMS 1A is defective Change the fuse 12. NO HF
HF ignition generator is defective Call after-sales service
13. WELDING CURRENT CANNOT
BE REGULATED
(without remote control unit)
The TC 1 MC AC (DC) control unit is
defective Change the TC 1 MC AC (DC) control unit
14. REMOTE CONTROL UNIT DOES
NOT WORK
(all other functions are OK)
10-pole remote control socket is faulty Change the remote control socket
AC: Tungsten electrode is alloyed up,
or domed tip is damaged
Incorrect needle diameter has been set
REMEDY CAUSE FAULT
Increase gas pre-flow time, esp. with lon-
ger hose packs Gas pre-flow time is set too short
HF is too weak See Pt. 11 below
Sharpen tip of tungsten electrode
DC: Tungsten electrode is alloyed up, or
pointed tip is damaged
Gas nozzle is dirty; HF jumps over the gas
nozzle onto the workpiece Use a new ceramic nozzle
Gas nozzle is too small for the diameter of
tungsten electrode used Use a bigger gas nozzle
Remote control cable is not properly con-
nected Plug in the remote control cable the right
way round, and screw it on as far as it will
go
Remote control cable is faulty Change the remote control cable
Remote control unit is faulty Change the remote control unit
