SYMPTOMS
POSSIBLE CAUSES
REMEDIES
The welding
wire speed is not
constant.
Debris is blocking 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-compatible with roller
• Covering wire guide in the torch non-compatible."
The wire-feeder
motor doesn’t ope-
rate.
Reel or roller brake too tight.
Release the brake and rollers.
Electrical supply problem.
Check that the power switch is in the "On" position.
Bad wire feeding.
Covering wire guide dirty or da-
maged.
Clean or replace
The drive roller is too loose
Tighten the drive roller knob
Reel brake too tight
Release the brake
No welding current
Bad connection to the main supply.
Check the mains connection and look if the plug is fed
by 400 V (3PH) power socket.
Bad earth connection.
Check the earth cable (connection and clamp condi-
tion).
Torch trigger inoperative.
Check the torch trigger / replace torch
The wire jams (after
the rollers)
Guide wire sheath crushed.
Check the sheath and torch body.
Wire jammed 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 bead is
porous
The gas flow rate is not sufficient.
Adjust flow range 15 to 20 L / min.
Clean the working metal.
Gas bottle empty.
Replace it.
Gas quality unsatisfactory.
Replace it.
Air flow or wind influence.
Prevent drafts, protect welding area.
Gas nozzle dirty.
Clean or replace the gas nozzle.
Poor quality wire.
Use suitable WIRE for MIG-MAG welding.
Surface to weld in bad condtion.
(rust, etc…)
Clean the metal before welding.
Very important
flashing particules.
Arc voltage too low or too high.
See welding settings.
Bad earth connection.
Adjust the earth cable for a better connection.
Insufficient gas flow.
Adjust the gas flow.
No gas flow at the
end of the torch.
Bad gas connection.
Check the gas connection at the welding machine.
Check the flowmeter and the solenoid valves.
The display shows
- - -
Overvoltage detected.
Check the voltage at the mains
The machine turns
on but nothing
appears on the
screen
The mains voltage is < 85V or >
265v
Check the voltage at the mains
