Selection of material type
Press the -key pad until the indicator for the
required material is switched on.
Selection of wire dimension
Press the -key pad until the indicator for the
required diameter is switched on.
Not all wire dimensions can be used for all
materials.
Reset to factory settings:
Factory settings for the selected wire dimension will
be reloaded when pressing the key pad until the
indicator gives a short flash.
Current/wire feed speed/material
thickness:
When the machine is not welding, the set
current/ wire feed speed/material dimension
is displayed. During welding the measured
current is displayed.
Material thickness:
The function helps adjusting the current according to
material thickness (in mm). When selecting material
thickness an automatically setting of current is
calculated. Thereafter, the current can be further
adjusted. The material thickness function can be seen
as a good starting point in the selection of correct
current and voltage. A trimming of these parameters
will be required in almost every welding task in order
to obtain the most optimum result.
Arc length
If necessary, the arc length can be
adjusted by trimming the voltage. The
measured voltage is shown during welding. Press the
-key pad and adjust from –9,9 to +9,9.
Control knob
This knob is used for adjusting welding
current, wire feed speed, material
thickness, arc length or secondary
parameters. Inching speed is adjustable
during wire inching. Max. wire feed speed is
18.0 m/min.
