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.

Figure 3 - Wire Feeding Motor
•
Loosen and lower the plastic knob (A) (Figure
3). Open the pressure arm (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 (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.
•
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 iden-
tifying the groove nearest that side.
•
Close the side panel of the machine.
•
Connect the power supply cable to the power
output line. Turn on the machine. Press the
torch switch. 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 switch.
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 stop 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 fee-
ding mechanism when working! The
rolls, when moving, may crush the fin-
gers. Periodically, check the rolls. Repla-
ce them when they are worn and com-
promise the regular feeding of the wire.
