TROUBLE SHOOTING
PROBLEM POSSIBLE CAUSE SOLUTION
Power source stops
Overheating protection activated due
to overload Protection automatically resets when
transformer has cooled (about 15 min)
No weld current
Rectifier blown Replace rectifier
No weld current
Bad connection between clamp &
workpiece Clean or grind contact surface and
weld area
Break in earth lead Repair or replace earth lead
Break in torch lead Repair or replace torch
Feed motor not working, lamp is on
Gear damaged or worn
Replace gears. (Contact service
agent)
Motor defective Replace motor (Contact service agent)
Wire does not feed, feed roller rotates Pressure roller improperly adjusted
Adjust tension
Dirt, copper, dust, etc, has collected in
torch liner Clean the liner from the machine
forward.
Use compressed air. If too much dirt,
replace the liner. Gas cup (Nozzle) or tip defective
Deformed wire
Check roller tension and adjust it if
necessary
Wire feeds unevenly
Dirt, etc, in liner
Clean the liner from the machine
forward
Gas cup (Nozzle) or Tip defective Replace gas cup (nozzle) and/or tip
Gas cup (Nozzle) spattered Clean or replace gas cup (nozzle)
Feed roller groove deformed Replace feed roller
Feed roller groove deformed Replace fedd roller
Pressure roller tensión improper Adjust tension
Unestable arc
Incorrect settings Check settings
Impurities in Weld area Clean and/or grind workpiece
Worn or detfective gas cup (nozzle) Rplace gas cup (nozzle)
Porous weld
No gas Open gas cylinder, regulate gas flow
Gas cup clogged Clean or replace cup (nozzle)
Draft blowing away shielding gas
Screen off weldind site or increase gas
flow
Rusty or dirty joints Clean and/or grind workpiece
Torch too far from or at wrong angle to
work The distance from gas cup to
workpiece should be 8- to 10mm
Gas leak
Check hoses, connections and torch
assembly. (Section 3.5).
Press the gas cup in correction
position
Faulty Electorvalve Clean out or replace
Electrode sticking in gas cup (nozzle)
Worn or defective gas cup (nozzle) gas cup (nozzle)
Electrode deformed Check roller tension
Wire speed too slow See recommendations for wire speed
Irregular weld bead
Torch incorrectly held Use correct torch angle
Wire weaving in weld pool Check roller tension and adjust as
needed.
Weld bead too narrow and raised
Weld current too low Increase power and wire speed
Weld speed too high
Move torch slower and weave a little
more
Weld bead too wide
Weld current too hight Decrease pwer and wire speed
Weld speed too low Move torch faster and weave less
Arc too long Bring torch closer to workpiece
Poor penetration
Weld current too low Increase power and wire speed
Arc too long Bring torch closer to workpiece
Excessive penetration
Weld current too high Decrease power and wire speed
Weld speed too slow Move torch faster
Incorrect distance of torch to
workpiece
Torch distance shoud be 8-10mm
