Fronius MAGIC WAVE 2000 FUZZY Bedienungsanleitung & Ersatzteilliste Seite 48

FAULT
9. NO GAS POST-FLOW
Tungsten electrode discolours after
end of welding
10. POOR ARC IGNITION
11. HF IS TOO WEAK
12. NO HF
13. WELDING CURRENT CANNOT
BE REGULATED
(without remote control unit)
14. REMOTE CONTROL UNIT DOES
NOT WORK
(all other functions are OK)
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!

CAUSE
Gas post-flow time is set too short
Gas pre-flow time is set too short
HF is too weak
DC: Tungsten electrode is alloyed up, or
pointed tip is damaged
AC: Tungsten electrode is alloyed up,
or domed tip is damaged
Incorrect needle diameter
Tungsten electrode is underloaded (with
especially negative consequences in AC)
Gas nozzle is dirty; HF jumps over the gas
nozzle onto the workpiece
Gas nozzle is too small for the diameter of
tungsten electrode used
Torch is damaged:
insulated torch components such as torch
body, protective hose etc. are faulty
Ignition device (ZMW 20) is faulty
No shielding gas, or not enough
[TC 1 MC AC (DC) module]
Fuse F1 on TMS 1A is defective
HF ignition generator is defective
The TC 1 MC AC (DC) control unit is
defective
Remote control cable is not properly con-
nected
Remote control cable is faulty
Remote control unit is faulty
10-pole remote control socket is faulty

REMEDY
Using internal program parameters, in-
crease the gas post-flow time (depends
on welding amperage - see p. 12 Pt. 2)
Increase gas pre-flow time, esp. with lon-
ger hose packs
See Pt. 11 below
Sharpen tip of tungsten electrode
Shorten the tungsten electrode and form
a new dome at the tip (see p. 11, Pt.
has been set
Use a suitable electrode for the ampera-
ge (also start-arc amperage) in question
Use a new ceramic nozzle
Use a bigger gas nozzle
Replace the damaged parts or change
the torch
Call after-sales service
See Pt. 8 above
Change the fuse
Call after-sales service
Change the TC 1 MC AC (DC) control unit
Plug in the remote control cable the right
way round, and screw it on as far as it will
go
Change the remote control cable
Change the remote control unit
Change the remote control socket
