Selecting welding process
Use this key to choose between MIG or MMA
welding.
TIG welding can be selected under secondary
parameters, once MMA welding has been chosen.
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
and secondary parameters. Max. wire feed speed is
12.0 m/min.
Setting of secondary parameters MIG
Press the control knob until the requested
parameter is displayed. To return to normal display
the key pad for arc length or current/wire feed
speed/material thickness is to be pressed briefly.
Arc adjust
Arc adjust (electronic choke) makes it possible to
adjust the speed of reaction to short-circuits.
Arc adjust can be set in steps from -5.0 to +5.0.
Burn back
The burn back function prevents the welding wire
sticking to the workpiece at the end of a weld.
Burn back can be adjusted between 1 and 30
Setting of secondary parameters MMA
Press the control knob until the requested
parameter is displayed. To return to normal display
the key pad for current is to be pressed briefly.
Arc power (MMA)
The arc power function is used to stabilise the arc in
MMA welding. This can be achieved by increasing welding
current during the short-circuits. The additional current
ceases when the short circuit is no longer present.
Arc power can be set between 0 and 150%.
MMA-hotstart (MMA)
MMA-hotstart helps establish the arc when welding
starts. When the electrode touches the work material, the
welding current automatically increases. The increased
start current is held for a fixed time, after which it drops
to the value, which has been set for the welding current.
The hotstart-value is the percentage of set current to
which the start current is increased. It can be set between
0 and 100 % of the set current.
TIG welding
This parameter is OFF as standard.
Select TIG welding by setting the parameter at . Arc
power and MMA hotstart are deactivated during TIG
welding.
The adjusted parameters are saved internally in the
machine when the machine is turned off.
Simultaneously, the number of the MIG-program in use is
saved so the machine will start up in this.
Welding voltage indicator
The welding voltage indicator is illuminated for
reasons of safety and in order to show if there is voltage
at the electrode or torch.
Temperature fault
The indicator is switched on, when the power source
is overheated.
