press bearing O presses the wire onto the roller F.

During the insertion of aluminum wires, especially of
diameters 0.8 and 1mm, difficulties might arise dur-
ing wire insertion in the gun tube assembly; in this
case, we recommend to disassemble it, (BEFORE
UNSCREWING THE GUN TUBE ASSEMBLY STOP
THE WATER FLOW) and once the wire has come out
of the aluminum body, re-assemble the gun tube
assembly manually inserting the wire. Make sure that
the wire comes out of the contact tip. It is extremely
important that the gun tube assembly is tightly
screwed, in order to avoid leakage and bad contacts
once the water flow has been re-opened.
4 WELDING.
4.1 SETTING OF THE PUSH-PULL WELDING TORCH
ACCORDING TO THE MATERIAL TO BE WELDED.
Make sure that the welding machine is set for the wire
diameter and type of material to be welded.
Make sure that the PUSH-PULL welding torch mounts a
roller with diameter corresponding to the wire to be
used and the right contact tip. Set the power source
current, according to the job to be carried out.
Get close to the welding point and press the welding
torch button I.
Using the «UP-DOWN» button P and according to the
power source, you can adjust the welding current or
modify the welding wire speed.
For welding iron or stainless steel wires for longer peri-
ods, we recommend to replace the PA CARBON sheath
with a metal sheath (see the paragraph 2.1).
After replacing the PA CARBON sheath with a metal
one, re-assemble the wire channel previously disassem-
bled inside the power source central adapter.
