Check if wire is in place and replace if necessary. Wire spool is empty.
No pressure on the drive roller;
insufficient or excessive pressure on the
drive roller.
Adjust the drive pressure.
PROBLEM POSSIBLE CAUSE COURSE OF ACTION
Arc works but not
feeding wire.
TROUBLESHOOTING
MIG WELDING ISSUES
Adjust the drive pressure.
Too much pressure on drive roller.
Replace contact tip.
The contact tip is clogged or damaged.
The contact tip size is too small.
Replace parts. Worn guides or drive roll alignment.
W i r e i s “ b i r d -
nesting” at the drive
roller or jamming.
Low output or non-
penetrating weld.
Adjust welding parameters. The welding current is too low.
Use .030" (0.8mm) - .035" (0.9mm) wire. Wrong type or size wire.
Reposition clamp and check cable to clamp connection.
Check connection of ground cable, gun, and Wire Polarity
Drive Lead.
Poor ground connection or gun
connection.
Use .030" (0.8mm) or 0.035" (0.9mm) contact tip with the
corresponding wire. Replace contact tip if worn.
Wrong size or worn contact tip
Have a qualified electrician verify the voltage at your outlet.
If the voltage is appropriate, verify that the circuit wiring is
sufficient for the circuit breaker size.
Input power too low.
Decrease stick out (the amount the wire extends past the
contact tip).
Stick out too long.
Work clamp, ground
cable, and/or weld-
ing cable get hot.
Check the connection of the work clamp and gun to the ma-
chine. Check the connection of the MIG Gun. Check con-
nection of the ground cable to the work clamp. Tighten ca-
ble connection to work clamp if needed. Ensure the contact
between the work clamp and workpiece is good and on a
clean, bare metal surface. Make sure the cable is not dam-
aged.
Bad ground or loose ground connection.
Clean or replace nozzle as needed.
Spatter or Slag build-up inside nozzle or
nozzle is clogged. Gun nozzle arcs to
work surface.
Wire feed speed is set too low for volt-
age setting being used.
Wire burns back to
contact tip.
Increase wire feed speed (turn left knob clockwise).
Stick-out too short.
Increase stick-out (the amount the wire extends past the
contact tip).
Wrong size contact tip. Use correct size contact tip.
Contact tip is clogged or damaged. Replace contact tip.
Reduce the burn back time setting. Burn back time setting is too long.
