Symptoms Reasons Solutions
The welding wire speed is not
constant.
Cracklings block up the opening.
Clean out the contact batch or change
it and replace the anti-adherence
product. Ref.041806
The wire skids in the rollers.
Control the roller pressure or replace
it.
Wire diameter non-consonant with
roller.
Covering Wire guide in the torch non-
consonant.
The unwinding motor doesn't operate.
Reel or roller brake too tight. Release the brake and rollers.
Electrical supply problem.
Check that the running button is on
the position on.
Bad wire unwinding.
Covering wire guide dirty or damaged. Clean or replace
Reel brake too tight Release the brake
No welding current
Bad connection to the main supply.
See the branch connection and look if
the plug is fed by 3 phases.
Bad earth connection.
Control the earth cable (connection
and clamp condition).
Power contactor inoperative. Control the torch trigger.
The wire rubs down after the rollers.
Covering wire guide crushed. Check the covering and torch body.
Locking of the wire in the torch Clean or replace.
No capillary tube. Check the presence of capillary tube.
Wire speed too fast Reduce the wire speed
The welding cord is porous
The gas ow rate is not sufcient.
Adjusting ow range 15 to 20 L / min.
Clean the working metal.
Gas bottle empty. Replace it.
Gas quality non-satisfying. Replace it.
Air ow or wind inuence. Avert air blast, protect welding area.
Gas nozzle too full. Clean or replace the gas nozzle.
Bad wire quality.
Use adapted WIRE for MIG-MAG
welding.
Surface to weld in bad condtion. (rust,
etc, ...)
Clean the working parts before
welding.
Very important ashing particules.
Arc voltage too low or too high. See welding settings.
Bad earth connection.
Check and place the earth cable to
have a better connection.
Protecting gas insufcient. Adjust the gas ow.
No gas at the torch output. Bad gas connection.
See if the gas coupling beside the
engine is well connected. Check the
owmeter and the solenoid valves.
