TROUBLE SHOOTING
PROBLEM
Weld current interrupted
No weld current, fuse blowing in
13amp plug
No weld current
Feed motor not working
Wire does not feed, feed roller
rotates
Wire feeds unevenly
Unstable arc
Porous weld
Wire sticking in gas cup
(nozzle)
Irregular weld head
Weld bead too narrow and
raised
Weld bead too wide
Poor penetration
Excessive penetration
POSSIBLE CAUSE
Overheating protection activated due
to overload
Rectifier blown
Bad connection between clamp and
work piece
Break in earth lead
Break in torch lead
Gear damaged or worn
Motor defective
Pressure roller improperly adjusted
Dirt, copper, dust, etc. have collected
in torch liner
Gas cup (nozzle) or tip defective
Deformed wire
Dirt, etc, in liner
Gas cup (nozzle) or tip defective
Gas cup (nozzle) spattered
Feed roller groove clogged
Feed roller groove deformed
Pressure roller tension incorrect
Incorrect settings
Impurities in weld area
Worn or defective gas cup (nozzle)
No gas
Gas cup clogged
Draft blowing away shielding gas
Rusty/dirty joints
Torch too far from, or at wrong angle to,
workpiece
Gas leak
Worn or defective gas cup (nozzle)
Wire deformed
Wire speed too slow
Torch incorrectly held.
Wire weaving in weld pool
Weld current too low
Weld speed too fast
Weld current too low
Weld speed too fast
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 (approx. 15 min).
Replace rectifier
Clean or grind contact surface and weld area
Repair or replace earth lead
Repair or replace
Replace gears
Replace motor (Contact service agent)
Adjust wire tension
Clean the liner from the machine forward
Replace gas cup (nozzle) and/or tip
Check roller tension
Clean the liner from the machine forward using
compressed air.
Replace gas cup (nozzle) and/or tip.
Clean or replace gas cup (nozzle)
Clean feed roller.
Replace feed roller.
Adjust tension.
Check settings
Clean and/or grind workpiece
Replace gas cup (nozzle)
Open gas cylinder, regulate gas flow
Clean or replace cup
Screen off welding site or increase gas flow
Clean or grind the workpiece
Gas cup to workpiece should be 8-10mm. Torch angle
approx 75°.
Check hoses, connections and torch assembly.
Replace gas cup (nozzle)
Check roller tension
Increase wire speed
Use correct torch angle.
Check roller tension and adjust
Increase power and wire speed.
Move torch slower and weave a little more
Increase current and wire speed.
Move torch faster and weave less
Increase current and wire speed.
Bring torch closer to workpiece
Decrease current and wire speed
Move torch faster
Torch distance should be 8-10mm
