Location Of Errors / Trouble Shooting - Migatronic KMX 550 Manual De Instrucciones

LOCATION OF ERRORS
Two error situations are registered: Machine over-
heating error and torch cooling error. All errors are
shown for as long as the error exists.
Machine overheat error
Overheating of the machine due to in-
Origin:
correct 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
full speed.
If the error is not caused by incorrect

use, MIGATRONIC's Service Depart-
ment has to be called in.
Torch cooling error
There is no flow or insufficient flow of
Origin:
cooling water in the torch.
Consequence: The welding process is interrupted
and post-flow starts. The LED with the

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 necessary.
2. Worn out contact tip.
