•
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 2 cm 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.
When loading wire and watching for it to come through the torch neck, to avoid
injury, do not hold the torch close to your face, instead, direct the wire toward the
floor. To avoid injury, do not place fingers near the wire feed rolls when the wire
feeder is operating.

-ENGLISH-
•
Open the side panel.
•
Loosen the nut (1) of the spool holder (brakedrum) and
remove the spring (2) and the external ring (3). (Fig.4)
•
Remove the plastic protection from the spool (4) and
place the wire spool on the spool holder.
•
Mount the external ring (3), the spring (2) and the pla-
stic lock nut (1) 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, whi-
le 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 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 appe-
ars at the end of the torch neck.
