Selecting welding process
1
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
CrNi
required material is switched on.

Selection of wire dimension

Press the -key pad until the indicator for the
0.9
required diameter is switched on.
0.8
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
5
If necessary, the arc length can be adjusted by
trimming the voltage. The measured voltage is
shown during welding. Press the
from -9,9 to +9,9.

Control knob
6
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
7
Press the keypad until the requested parameter is
displayed. Turn the control knob up and down until
the requested value is displayed. Press the key for arc
length or current/wire feed speed/material thickness
briefly to return to normal display.
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 key pad until the requested parameter is
displayed. Turn the control knob up and down until
the requested value is displayed. Press the key for
current briefly to return to normal display.
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
the control knob. 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
8
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
9
The indicator is switched on, when the power source is
overheated.
