5.4 Function explanations
Burnback time
Burnback time is a delay between the time when the wire starts to brake 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 solidifying 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 low speed until it comes into electrical
contact with the workpiece and then the speed increases to the set speed.
2 stroke
With 2 stroke, the gas flow and wire feed start when the trigger switch is pressed in
and end when it is released.
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.
Wire feed speed
This sets the required feed speed of the filler wire in m/minute.
