TROUBLESHOOTING GUIDE

PROBLEMS
(SYMPTOMS)

Poor arc characteristics in all
processes.

POSSIBLE AREAS OF
MISADJUSTMENT(S)

1.

Check for the correct input volt-
ages on the three- phase input
lines at the DC600.

2.

Make sure the proper welding
procedures are being
used.(wire feed speed, arc volt-
age and wire size).

3.

Check the welding cables for
loose or faulty connections.
