mount the wire coil d on the support, making sure to align
the coil hole with the pin f on the support e. once the coil
has been mounted, the wire must be aligned with the entry
hole of the wire guide K.
use the wire feeder roller G suited to the type of material to
be welded and to the wire diameter in use. the diameter
and type of groove are engraved on the visible side.
if the roller must be replaced:
release the arm of the wire press bearing h.
unscrew the screws I and remove the guard l.
remove the wire feeder roller G, take the appropriate roller
and insert it so that the groove to be used is facing inward.
mount the guard l and fasten with its screws I.
insert the wire in the guide K and, passing over the roller
groove, insert it a few centimeters into the sleeve a1.
release the arm of the wire press bearing h, making sure
that the wire remains inside the roller groove G.
• Important: when welding with aluminum wires, and
especially wires of Ø 0.6 or 0.8mm, it is extremely impor-
tant to set the clutch m at minimum pressure, whereas
for all other wires it is sufficient to turn a few cycles on the
clutch in order to achieve the correct pressure.
close the door of the coil compartment and turn on the wel-
ding machine.
select the welding program suitable for the wire to be used.
3.1.2 preparing the wire feed unit of the pull 2003
torch.
use the wire feeder roller with the groove corresponding to
the wire diameter to be used. the diameter is engraved on
one side of the roller itself.
if the roller must be replaced:
• unscrew the knob n and pull it outward.
• remove the guard o so as to be able to view the wire fee-
der group.
• unscrew the nut p, turning it clockwise.
• Press the lever Q to remove the roller r.
• unscrew the gas nozzle s and the contact tip t.
• Press the lever Q to raise the wire press bearing u, to pre-
vent the wire from encountering any obstacles when first
inserted.
• Press the torch trigger V to the wire forward, until it leaves
the gun tube assembly z.
it is best to move it forward at reduced speed.
• We recommend stopping the wire when it leaves the guide

X, and then moving the wire forward in small segments until
it enters the guide y and leaves the gun tube assembly z.
• insert the roller, positioning the collar r1 as shown in the
figure.
• tighten the nut p by turning it counter-clockwise.
• make sure that the wire is positioned within the groove of
the wire feeder roller r, then release the lever Q so that the
wire press bearing u presses the wire against the roller r.
• return the guard o to position, tightening it by means of the
knob n.
• screw on the contact tip t and the gas nozzle s.
4 WeldInG
4.1 preparInG the pull 2003 torch for the
tYpe of materIal to Be Welded.
make sure that the welding machine is set up for the wire
diameter and type of material to be welded. make sure that
the torch Pull 2003 mounts the roller r of the diameter
matching the wire to be used and the contact tip t of the
proper diameter.
set the current, on the power source, corresponding to the
type of work to be done.
approach the welding point and press the torch trigger V.
the " uP-doWn " button W makes it possible, depending
on the type of power source, to adjust the welding current
or adjust and correct the welding wire speed.
When welding with wires made of iron and stainless steel,
in order for the wire to advance properly, we recommend
raising the arm of the wire press bearing u, unscrewing the
allen screw J, with the wrench J 1 provided. the wire press
bearing u must just brush against the wire for maximum
welding performance.
if you need to weld iron or stainless steel wires for long
periods, we recommend replacing the teflon liner with the
metal liner art 1464.01 (see paragraph 2.1).
after replacing the teflon liner with the metal one, reassem-
ble the metal sleeve a inside the central adapter of the
power source.
