4.2.3 MOG/MAG process
Here, the wear and tear element is the contact tip of the torch
which will be exchanged always with the same diameter as
the continuous wire being used. The nozzle of the torch will
also suffer from wear and tear due to high temperatures and
projections. The elements are of easy manual disassembly by
simple wide pitched threads. For special welding of aluminum,
contact your distributor regarding the replacement of the Teflon-
based low-friction inner conduct (liner).
The spooler mechanism No. 8 presents easy to operate
replacement of the grooved presser rollers (pulley wheels).
This is done by releasing the threaded knob that releases the
pulley wheel, the position of which may be reversed to select the
supplementary diameter (for example 0.8 mm at one side and
1.0 mm at the other). Note: Be careful not to lose the pin (of the
spooler) when releasing the pulley wheel.
The welding wire is received from its reel and installed by
introducing it into the axle of the spooler and guiding it to the
outlet of the torch through traction grooves No. 8 of the hose of
the torch No. 1 and the contact tip of the torch. The contact tip
may be accessed by removing the nozzle from the torch No. 1
by rotating it by hand.
The contact tip is removed with a fixed spanner or pliers, and it
must be of the same diameter as the welding wire. The pulley
wheels are accessed removing the pressure bearing that
releases them. Once the wire has been passed through the
pulley wheels, close the presser rollers and adjust pressure to
make the wire advance correctly without sliding and without
being crushed.
The groove of the pulley wheel must be of the same diameter as
the welding wire.
When using hollow wire, the nozzle may be removed from the
torch as it is not required. In this way it will have more visibility
and not harm the nozzle with projections.

MIG/MAG SPECIAL SETTINGS
Depending on the transfer mode, for instance when the user
wishes to work with short arc (coarse drop, short-circuit) or
wishes to work in long-arc mode (fine drop, spray), it is possible
to act on two detail setting controls.
