Wire Loading

ENSURE THE GAS AND ELECTRICAL SUPPLIES ARE DISCONNECTED. BEFORE
PROCEEDING, REMOVE THE NOZZLE AND THE CONTACT TIP FROM THE
TORCH.
• Open the side panel.
• Loosen the nut of the spool holder (brake drum)
and remove the spring and the external ring. (Fig.4)
• Remove the plastic protection from the spool (4) and
place the wire spool on the spool holder.
• Mount the external ring, the spring and the
plastic lock nut again. These parts form the braking
system of the wire spool speed. NOTE: Do not
tighten the nut too much. Excessive pressure strains
the wire feeding motor, while too little pressure does
not allow the immediate stop of the wire spool at the
end of the welding.
• Loosen and lower the plastic knob (A) (Fig.5). Open
the pressure arm (B) of the feeder
• Disconnect the wire from the edge of the wire spool being
careful to keep tension on the end of the wire. Cut off a
short section of the end of the wire to insure a straight end.
Insert the straight end into the wire inlet guide (C) past
the wire feed roll and into the wire liner. Lower pressure
arm (B) and lift pressure adjustment knob (A) into place. Connect the input power cord and
turn on the welder. Press the torch trigger and observe the wire feeding into the torch liner.
Adjust the pressure on the wire with knob (A) to insure smooth feeding without slippage. Do
not over-tighten the pressure adjustment as it may damage the motor. Close the welder side
panel. Remove the nozzle and contact tip from the welding torch. Straighten the torch cable
to remove any coils or kinks. Squeeze and hold the torch trigger until the wire appears at the
end of the torch neck. Turn off the welder and install the contact tip and nozzle.
WARNING: Keep the torch straight. When feeding a new wire through the liner, make sure
the wire is cut cleanly (no burrs or angles) and that at least 1" from the end is straight (no
curves). Failure to follow these instructions could cause damage to the liner.
WARNING: When changing the wire diameter being used, or replacing the wire feed roll,
be sure that the correct groove for the wire diameter selected is inside, closest to the machine.
The wire is driven by the inside groove. Feed rolls are marked on the side identifying the groove
nearest that side.
WARNING: To avoid injury, when loading wire and watching for it to come through the torch
neck do not hold the torch close to your face. Instead, direct it towards the floor. Do not place
fingers near the wire feed rolls when the wire feeder is operating.
