SYMPTOMS POSSIBLE CAUSES REMEDIES
Cracklings block up the opening. Clean out the contact batch or change it
and replace the anti-adherence product.
Ref.041806 The welding wire speed is not
constant.
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.
Reel or roller brake too tight. Release the brake and rollers. The unwinding motor doesn’t
operate.
Electrical supply problem. Check that the running button is on the
position on.
Covering wire guide dirty or
damaged. Clean or replace Bad wire unwinding.
Reel brake too tight Release the brake
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).
No welding current
Power contactor inoperative. Control the torch trigger.
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.
The wire rubs down after the
rollers.
Wire speed too fast Reduce the wire speed
The gas flow rate is not sufficient.
Adjusting flow range 15 to 20 L / min.
Clean the working metal.
Gas bottle empty. Replace it.
Gas quality non-satisfying. Replace it.
Air flow or wind influence. 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.
The welding cord is porous
Surface to weld in bad condtion.
(rust, etc…) Clean the working parts before welding.
Arc voltage too low or too high. See welding settings.
Bad earth connection. Check and place the earth cable to have
a better connection.
Very important flashing
particules.
Protecting gas insufficient. Adjust the gas flow.
No gas at the torch output. Bad gas connection. See if the gas coupling beside the engine
is well connected. Check the flowmeter
and the solenoid valves.
The Spool on Gun does not
work. Connection problem Check the torch connections (power and
control connectors).
In Spool Gun mode, the
welding bead is not regular The screw that set the tension of
the rollers is too tight. Wrong
position of the speed knob on the
spool gun. Loosen the tension screw of the rollers.
Set the wire speed with the setting knob
of the spool gun
