WIRE LOADING
Figure 2 - Spool Assembly
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). In the case you are replacing the wire
spool, extract it.
•
Remove the plastic protection from the spool.
Place it on the spool holder. Tighten the lock
nut turning it.
•
Mount the spacer as shown in the Figure 2 if
required for the spool to be installed.
•
Tighten the lock nut.
Tighten nut to appropriate tightness.
Excessive pressure strains the wire fee-
ding motor. Too little pressure does not
allow the proper wire feeding.

•
Loosen and lower the plastic knob (A) (Figure
3). Open the pressure arms (B) of the feeder.
(Extract the wire from the torch liner if some
wire is left into the torch).
•
When the wire is disconnected, grasp it with
pliers so that it cannot exit from the spool. If
necessary, straighten it before inserting it in
the wire input guide (C). Insert the wire on the
lower roll (D) and in the torch liner.
WARNING: keep the torch straight.
When feeding a new wire through the
liner, make sure the wire is cut cleanly

EN-6
(no burrs or angles) and that at least
2 cm from the end is straight (no cur-
ves). Failure to follow these instructions
could cause damage to the liner.
•
Lower the pressure arm (B) and place the knob
(A). Tighten slightly. If tightened too much, the
wire gets locked and could cause motor da-
mage. If not tighten enough, the rolls will not
feed the wire.
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.
The diameter of the grooves in the
rolls is identified by the different
color of the side plate. All four rolls
must always be replaced. Refer to the
specifications inside the wire feeder
motor compartment.
•
Close the side panel of the machine.
•
Connect the power supply cable to the power
output line. Turn on the machine. Press the
torch trigger. The wire fed by the wire feeding
motor at variable speed must slide through
the liner. When it exits from the torch neck,
release the torch trigger.
Note: after three seconds that torch
trigger is pressed wire feeding speed
increases to allow a fast exit of the wire
on the torch neck and gas stops flowing.
•
Turn off the machine.
•
Mount the contact tip and the nozzle.
When checking the correct exit of the
wire from the torch do not bring your
face near the torch, you may run the
risk to be wounded by the outgoing
wire. Do not bring your fingers close to
the feeding mechanism when working!
The rolls, when moving, may crush the
fingers. Periodically, check the rolls.
Replace them when they are worn and
compromise the regular feeding of the
wire.
