to overload
Rectifier blown
Bad connection between clamp &
workpiece
Break in earth lead
Break in torch lead
Gear damaged or worn
Motor defective
Pressure roller improperly adjusted
Dirt, copper, dust, etc, has collected in
torch liner
Use compressed air. If too much dirt,
replace the liner.

Torch too far from or at wrong angle to
work
Gas leak
Faulty Electorvalve
Worn or defective gas cup (nozzle)
Electrode deformed
Wire speed too slow
Torch incorrectly held
Wire weaving in weld pool
Weld current too low
Weld speed too high

Weld speed too low
Arc too long
Weld current too low
Arc too long
Weld current too high
Weld speed too slow
Incorrect distance of torch to
workpiece
SOLUTION
Protection automatically resets when
transformer has cooled (about 15 min)
Replace rectifier
Clean or grind contact surface and
weld area
Repair or replace earth lead

Adjust tension
Check settings
Clean and/or grind workpiece
Rplace gas cup (nozzle)
Open gas cylinder, regulate gas flow
Clean or replace cup (nozzle)
Screen off weldind site or increase gas
flow
Clean and/or grind workpiece
The distance from gas cup to
workpiece should be 8- to 10mm
Check hoses, connections and torch
assembly. (Section 3.5).
Press the gas cup in correction
position
Clean out or replace
gas cup (nozzle)
Check roller tension
See recommendations for wire speed
Use correct torch angle
Check roller tension and adjust as
needed.
Increase power and wire speed
Move torch slower and weave a little
more
Decrease pwer and wire speed
Move torch faster and weave less
Bring torch closer to workpiece
Increase power and wire speed
Bring torch closer to workpiece
Decrease power and wire speed
Move torch faster
Torch distance shoud be 8-10mm
