Wire feed test
When you press the Wire inch button (4), the wire feeder
engine starts feeding. The gas valve does not open, and
the power source is not activated.
The wire feed pace is 2 m/min for the first two seconds,
and then 10 m/min.
When the button is released, the wire feeding stops. The
machine automatically goes back to the normal state af-
ter approximately 3 seconds from release of the button or
immediately when you press the ESC button.
Retrieving weld data
The weld data function allows you to return to the weld-
ing current and voltage used during the previous session,
with the weld data feature. To use the feature, press but-
tons 3 and 4 simultaneously.
Selecting the welding process
The welding process selection button (7) allows you to se-
lect the welding process you want to use. You can select
one of the following processes:
• regular MIG welding
• 1-MIG welding
• WiseThin & WiseRoot (optional)
In regular MIG welding, the wire feed speed and weld-
ing voltage are adjusted separately. Unlike the above,
the 1-MIG, WiseThin and WiseRoot processes are synergic
welding processes where the welding voltage and other
welding parameters are interconnected so that the weld-
ing power and arc length are adjusted to attain optimal
welding values.
The WiseThin and WiseRoot processes are optional
features intended for welding automation. They must
be acquired separately by licenses and are therefore not
available in all configurations.
