TROUBLESHOOTING
NOTE: Weld quality is dependent on the correct consumables, proper Torch position/angles , and Product maintenance.
Description Possible Cause Corrective Action
1. Spool Torch:
Welding wire does not feed
into the
Spool Torch Drive
Rolls.
A The welding wire is jammed against the Swan
Neck Liner due to the welding wire not being
straight.
B The Spool Torch is not fitted with the correct
contact tip, Swan Neck Liner, and Drive Rolls
for the wire diameter & wire material.
C The contact tip is blocked with welding wire
debris OR the Liner is worn / filled with dirt
and debris.
D Wrong size Swan Neck Liner.
E Worn or broken Spool Torch Trigger Switch.
F Wrong size/type feed rolls for welding wire or
worn feed rolls in the Spool Torch.
A Remove welding wire from Spool Torch, remove
any burrs on the welding wire then straighten
end and feed welding wire into the Spool Torch.
B Check then replace any incorrect size parts in the
Spool Torch such as contact tip, Swan Neck
Liner, and Drive Rolls.
C Blow out Swan Neck and Swan Neck Liner with
clean, dried compressed air OR replace the con-
tact tip and the Swan Neck Liner.
D Change Swan Neck Liner to correct size/type for
welding wire.
E Test, if not working then replace.
F Change feed rolls to correct size/type for welding
wire or change worn feed rolls in the Spool
Torch.
2. Push-Pull Torch:
Welding wire does not feed
into the
Push-Pull Torch
Drive Rolls and a Birds
Nest may develop at the
MIG/MAG equipment Drive
Rolls.
NOTE : A Birds Nest is a
tangle of welding wire at
the Drive Rolls when the
welding wire stops due an
obstruction in a Torch Liner
while the Drive Rolls are
spinning.
A The Push-Pull Torch is not fitted with the cor-
rect contact tip, Swan Neck Liner, Torch Cable
Liner, and Drive Rolls for the wire diameter &
wire material.
B The contact tip is blocked with wire debris OR
the Liner is worn / filled with dirt and debris.
C Wrong size Push-Pull Torch Cable Liner and
Swan Neck Liner.
D Worn or broken Torch Trigger Switch
E Wrong size/type feed rolls for welding wire or
worn feed rolls in Push-Pull Torch and/or the
MIG/MAG equipment.
A Check then replace any incorrect size parts in the
Push-Pull Torch such as contact tip, Swan Neck
Liner, Torch Cable Liner, and Drive Rolls.
B Replace the contact tip and/or Liner, blow out
Torch Neck, Liner conduit with clean, dried com-
pressed air.
C Change Push-Pull Torch Cable Liner and/or Swan
Neck Liner to correct size/type for the welding
wire.
D Test, if not working then replace.
E Change feed rolls to correct size/type for welding
wire or change worn feed rolls in Push-Pull
Torch and/or the MIG/MAG equipment.
3. Welding wire creates a
Birds Nest at the MIG/MAG
equipment Drive Rolls.
Refer to 2. above for addi-
tional information on
Birds
Nest .
A The Push-Pull Torch is not fitted with the cor-
rect Torch Cable Liner and Swan Neck Liner for
the wire diameter & wire material.
B The welding wire is not entering the Push-Pull
Torch due to the mis-alignment between the
Torch Cable Liner and the Wire Inlet Guide.
C Inadequate Pressure Arm force to the Drive
Roll which causes the Welding Wire to slip on
the Drive Roll.
A Check then replace any incorrect size parts in the
Push-Pull Torch such as Swan Neck Liner, and
Torch Cable Liner.
B Make sure that the Push-Pull Torch is fixed into
the Push-Pull Torch Welding wire inlet guide.
C Increase the Pressure Arm force to the Drive Roll
by the
Pressure Arm Screw .
4. Torch is getting extremely
hot. A Contact tip or tip holder are not tightened
properly.
B Cooling system is not cooling effectively.
C Cooling system is not correctly connected.
D Torch Cable connections loose or defective.
A Make tighter using a suitable tool.
B Check then correct coolant flow, fluid level, or
cleanliness.
C Check connections (coolant inlet and return).
D Make Torch Cable / Swan Neck connections
tighter.
