GENERAL MAINTENANCE

DISCONNECT THE POWER SOURCE FROM THE MAINS BE-
FORE PERFORMING ANY MAINTENANCE WORK.
Every 5-6 months, remove accumulated dust from the inside of
the welding unit with a jet of dry compressed air (after removing
side panels).
BE EXTREMELY CAREFUL TO AVOID BENDING MOVE-
MENTS, WHICH COULD DAMAGE AND CHOKE THE TORCH.
GENERAL MAINTENANCE
APPEARANCE CAUSE AND REMEDY
- Poor preparation.
- Align edges and hold during spot welding.
- No-load voltage or welding speed too low.
- Incorrect torch inclination.
- Wire diameter too large.
- Welding speed too high.
- Welding voltage too low for welding application.
- Weld in the channel if using a long arc.
- Regulate voltage.
- Wire is bent or over-protruding from the wire guide tube.
- Incorrect wire feed speed.
- Incorrect torch inclination.
- Irregular or insufficient distance.
- Wire guide tube worn.
- Wire speed too slow for voltage used or for welding speed.
- Wire speed too high.
- Incorrect torch inclination.
- Excessive distance.
- Distance too short.
- Rough out or grind the weld, then repeat.
- Welding speed too high.
(This fault is easily detected on sight by the welder, and should be corrected im-
mediately.)
NEVER MOVE THE POWER SOURCE BY PULLING THE
TORCH.
PERIODICALLY CHECK THE CONDITION OF THE TORCH,
WHICH IS THE PART MOST SUBJECT TO WEAR.
8.1

TORCH MAINTENANCE:

1. GAS NOZZLE (6): periodically apply welding spray and
clean nozzle interior of residue.
To replace the nozzle:
- Turn the nozzle clockwise to remove
- Fit the new gas nozzle.
