TROUBLESHOOTING
SYMPTOMS POSSIBLE CAUSES REMEDIES
The welding wire speed is not
constant.
Debris is blocking up the opening.
Clean out the contact tip or change it and
replace the anti-adherence product.
The wire skids in the rollers.
- Check the roller pressure or replace it.
- Wire diameter incompatible with roller
- Covering wire guide in the torch
incompatible.
The wire skids in the rollers. Check and tighten the roller’s screws.
The torch lead is twisted.
The torch lead must be as straight as
possible.
The wire-feeder motor doesn’t operate.
Reel or roller brake too tight. possible.
Electrical supply problem.
Check that the power switch is in the «On»
position.
Bad wire feed.
Covering wire guide dirty or
damaged.
Clean or replace
Roller axle key missing Reposition the key.
Reel brake too tight Adjust the brake
No welding current.
Bad connection to the mains supply.
Check the mains connection and ensure the
supply is 400 V (3PH).
Bad earth connection.
Check the earth cable (connection and
clamp condition).
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 work-piece.
Gas bottle empty. Replace
Gas quality unsatisfactory. Replace
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.
Work-piece in bad condtion. (rust,
etc…)
Clean the metal before welding.
No gas connected
Check that the gas is connected to the
generator
The arc produces a lot of sparks
Arc voltage too low or too high. See welding settings.
Bad earth connection.
Check the earth cable (connection and
clamp condition)
Insufficient gas flow. Adjust the gas flow.
No gas flow at the end of the
torch.
No gas connection
Check that the gas pipe is plugged to the
correct connector.
Bad gas connection.
Check the gas connection at the welding
machine. Check the flowmeter and the
solenoid valves.
