TROUBLESHOOTING

SYMPTOMS
The welding wire speed is not
constant.
The wire-feeder motor doesn't
operate.
Bad wire feeding.
No welding current
The wire jams (after the
rollers)
The welding bead is porous
Very important flashing
particules.
No gas flow at the end of the
torch.
The display shows - - -
The machine turns on but
nothing appears on the screen
14
POSSIBLE CAUSES
Debris is blocking up the opening.
The wire skids in the rollers.
Reel or roller brake too tight.
Electrical supply problem.
Covering wire guide dirty or
damaged.
The drive roller is too loose
Reel brake too tight
Bad connection to the main supply.
Bad earth connection.
Torch trigger inoperative.
Guide wire sheath crushed.
Wire jammed in the torch
No capillary tube.
Wire speed too fast
The gas flow rate is not sufficient.
Gas bottle empty.
Gas quality unsatisfactory.
Air flow or wind influence.
Gas nozzle dirty.
Poor quality wire.
Surface to weld in bad condtion.
(rust, etc...)
Arc voltage too low or too high.
Bad earth connection.
Insufficient gas flow.
Bad gas connection.
Overvoltage detected.
The mains voltage is < 85V or >
265v
REMEDIES
Clean out the contact batch or change it
and replace the anti-adherence product.
Ref.041806
- Control the roller pressure or replace it.
- Wire diameter non-compatible with
roller
- Covering wire guide in the torch non-
compatible.
Release the brake and rollers.
Check that the power switch is in the
"On" position.
Clean or replace
Tighten the drive roller knob
Release the brake
Check the mains connection and look if
the plug is fed by 400 V (3PH) power
socket.
Check the earth cable (connection and
clamp condition).
Check the torch trigger / replace torch
Check the sheath and torch body.
Clean or replace.
Check the presence of capillary tube.
Reduce the wire speed
Adjust flow range 15 to 20 L / min.
Clean the working metal.
Replace it.
Replace it.
Prevent drafts, protect welding area.
Clean or replace the gas nozzle.
Use suitable WIRE for MIG-MAG welding.
Clean the metal before welding.
See welding settings.
Adjust the earth cable for a better
connection.
Adjust the gas flow.
Check the gas connection at the welding
machine. Check the flowmeter and the
solenoid valves.
Check the voltage at the mains
Check the voltage at the mains
