This chart will assist you in resolving common problems you may
encounter.
PROBLEM POSSIBLE CAUSE POSSIBLE SOLUTION
No “life” from welder.
Input cable or plug malfunction. Check for proper input cable connection.
Wrong size fuse. Check fuse and replace as necessary.
Fan operates normally, but when gun trigger
pulled, there is no wire feed, weld output or
gas flow.
Faulty trigger on gun. Replace torch trigger.
Thermostat intervention.
Allow welder to cool. The extinguishing of the pilot lamp / switch on
the front panel indicates the thermostat has closed.
Feed motor operates but wire will not feed.
Faulty wire feeding motor (rare). Replace wire feeding motor.
Insufficient feed roller pressure. Increase roller pressure.
Burr on end of wire. Re-cut wire square with no burr.
Liner blocked or damaged. Clear with compressed air or replace liner.
Lack of penetration.
Voltage or wire feed speed too low. Re-adjust the welding parameters.
Loose connection inside the machine (rare). Clear with compressed air and tighten all connections.
Worn or wrong size contact tip. Replace the contact tip.
Loose gun connection or faulty gun assembly. Tighten or replace torch.
Wrong size wire. Use correct size welding wire.
Torch moved too fast. Move the gun smoothly and not too fast.
Wire is birdnesting at the drive roller.
Eccessive pressure on drive roller. Adjust pressure on drive roller.
Gun liner worn or damaged. Replace wire liner.
Contact tip clogged or damaged. Replace contact tip.
Liner stretched or too long. Cut wire liner at the right lenght.
Wire burns back to contact tip.
Contact tip clogged or damaged. Replace the contact tip.
Wire feed speed to slow. Increase wire speed.
Wrong size contact tip. Use correct size contact tip.
Bad connection from cable to clamp. Tighten connection or replace cable.
Slag buildup inside nozzle or nozzle is shorted. Clean or replace nozzle.
Workpiece clamp and/or cable gets hot. Wire feed speed too fast. Decrease wire feed speed.
Gun nozzle arcs to work surface. Nozzle clogged. Clean or replace nozzle.
Wire pushes torch back from the workpiece.
Torch held too far from the workpiece. Hold the torch at the right distance.
Bad connection between earth clamp and
workpiece.
Clean and deoxidate the contact area of the earth clamp.
The workpiece is excessively oxidized or painted. Brush carefully the point to be welded.
Poor quality welds.
Insufficient gas at weld area.
Check that the gas is not being blown away by drafts and if so move
to more sheltered weld area. If not check gas cylinder contents
gauge, regulator setting and operation of gas valve.
Rusty, painted, damp, oil or greasy workpiece. Ensure workpiece is clean and dry.
Rusty or dirty wire. Ensure wire is clean and dry.
Poor ground contact. Check ground clamp/workpiece connection.
Incorrect gas / wire combination. Check on the manual for the correct combination
Weld deposit “stringy” and incomplete.
Torch moved over workpiece too quickly. Move the torch slower.
Gas mixture incorrect. See shielding gas table.
Weld deposit too thick.
Torch moved over workpiece too slowly. Move the torch faster.
Welding voltage too low. Increase welding voltage.
Display not clear. Set display contrast.
When welder is turned on, the display shows
ERR1 and / or ERR2.
Failure of system memory. Contact the service center.
