Wire feed sp eed
This sets the r equired feed speed of the filler wire in m/minute.
2stroke
With 2--stroke, the gas flow starts followed by the wire feed when the trigger switch is
pressed in. The welding process is concluded when the trigger switch is released,
the wire feed stops and the gas stops flowing.
4stroke
With 4 stroke, the gas flow starts when the trigger switch is pressed in and the wire
feed starts when it is released. The welding process continues until the switch is
pressed in again, the wire feed stops and when the switch is released the gas stops
flowing.
Wire inch
Cold wire feed is used to feed wire without welding voltage and gas flow.
Activation of cold wire feed: press in the trigger switch and the wire feed starts.
Gas purging
Gas purging is used to measure that gas flow or to flush the gas hoses to clean them
of any air and moisture before commencing welding. Gas purging is carried out with
the voltage and wire feed disabled.
Activation of gas purging: press in the trigger switch and gas purging starts.
