3.11.2 Arc force

For a stable arc when MMA welding, it is important to ease the droplet form
material transfer using very short current impulses in addition to the selected
current I . The level of these current impulses is determined by the selected Arc
1
Force. The press and rotate button [27] can be used to steplessly set the Arc
Force between 0% and 70% of the selected current I
i.e. Arc Force 50% and welding current I

3.11.3 Hot Start

To better ignite the electrode when MMA welding, at the start of welding a slightly
higher level of current is used than the set welding current I
Start determines this level. The press and rotate button [27] can be used to
steplessly set this between 0% and 70% of the selected current I
maximum Imax., i.e. Hotstart 30% and welding current I

Control LEDs

REMOTE CONTROL ACTIVATED control light [14]
When a remote control element is connected and active, the
LED lights.
Control lamp for OPERATION [15]
Open circuit voltage is available at the torch or electrode
holder.
Control lamp for TEMPERATURE [16]
The LED (yellow) lights when the temperature limit value is
reached. As long as this LED is lit up, the power supply is
switched off and there is no output voltage available. When
TIG welding, after the power supply is switched off, the preset
gas post-flow time starts. After the unit has cooled down, the
LED goes out and you can automatically start welding again.
