Explanation of function

Wire feed speed
This sets the required feed speed of the filler wire in m/minute.
2 stroke
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.
4 stroke
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.
Spot welding
Spot welding is used when you want to weld on short, repeated occasions with a
pre--set time.
When the trigger switch is pressed in, the gas flow starts for a period of time
governed by the printed circuit board. After this the welding process starts for the set
time. When the welding process is complete, the gas flow stops.
Cold wire feed
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 switched off.
Activation of gas purging: press in the trigger switch and gas purging starts.
Burnback time
Burnback time is a delay between the time when the wire brakes until the time when
the power source switches off the welding voltage. Too short burnback time results in
a long wire stickout after completion of welding, with a risk of the wire being caught
in the weld pool. Too long a burnback time results in a shorter stickout, with
increased risk of the arc striking back to the contact tip.
Creep start
Creep start means that the wire is fed at 50% lower speed until it comes into
electrical contact with the workpiece, at which point the speed increases to the set
speed.
