LOCATION OF ERRORS
One error situation is registered: Machine over-
heating error. The error is shown for as long as the
error exists.
Machine overheat error
Origin: Overheating of the machine due to
incorrect use, e.g. exceeding the
duty cycle of the machine for the
welding current in use.
Consequence: The welding process is interrupted
and post-flow starts. The LED with
the symbol for overheat is lit. Fan
runs at max. speed.
Remedy: If the error is not caused by incorrect
use, MIGATRONIC's Service Depart-
ment has to be called in.
TROUBLE SHOOTING
The wire feed has stopped
1. The inlet nozzle and the wire are not in alignment
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 up.
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 up
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 ne-
cessary.
2. Worn out contact tip.
