8.0 GENERAL MAINTENANCE
DISCONNECT THE POWER SOURCE FROM THE MAINS BEFORE 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 MOVEMENTS, WHICH COULD
DAMAGE AND CHOKE THE TORCH. NEVER MOVE THE POWER SOURCE BY
PULLING THE TORCH.
PERIODICALLY CHECK the condition of the torch, which is the part most sub-
ject to wear.

TORCH MAINTENANCE:
TYPE OF BREAKDOWN
No functions operate.
Irregular wire feed.
GENERAL MAINTENANCE
APPEARANCE
POSSIBLE CAUSES
Faulty power cord (one or more
phases disconnected).
Blown fuse.
Insufficient spring pressure.
Wire-guide sheath blocked.
(GB) 5
CAUSE AND REMEDY
- 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 immediately.)
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.
2.
WIRE GUIDE TUBE ( 7 ) : check the wire passage of the tube for wear.
Replace as necessary.
To replace the nozzle:
-Turn the gas nozzle (6) clockwise to remove.
-Unscrew wire guide tube (7) .
-Press the torch button; after a few seconds the wire will protrude from the torch
neck.
-Fit the new wire guide tube (7) .
-Replace the gas nozzle (6) .
-Trim excess wire.

CONNECTING THE TORCH
Prior to connecting the torch, make sure that the wire sheath (18) is suited to the
diameter of the wire used:

- BLUE Ø 1.5 for wire Ø 0,6- 0.8 mm.
- RED Ø 2.0 for wire Ø 1 - 1.2 mm.
(Wire sheath colour for steel wire).
