Trouble Shooting / Technical Data - Migatronic FLEX 330XMA Manuel D'instruction

TROUBLE SHOOTING
The wire feed has stopped
1. The inlet nozzle and the wire are not in align-
ment with each other.
2. The reel of wire is too taut, the wire must come
off the reel evenly.
3. The inlet tube or contact tip is badly worn or is
blocked.
4. The welding wire is not clean or it is rusty. It
could also be of an inferior quality.
5. The pressure roller has to be tightened.
Spatter
1. The wire feed is too fast for the voltage setting.
2. Worn out contact tip.
Porous weld. A cone is formed when spot
welding
1. Contact tip is blocked.
2. A leak in the gas hose draws in air which mixes
with the shielding gas.
The wire keeps sticking in the contact tip and
feeds very slowly
1. Any damaged wire should be cut off, pulled out
and replaced. The pressure on the wire feed
roller should be checked and adjusted if neces-
sary.
2. Worn out contact tip.
