5.1.1
Welding control mode
2-stroke
With 2-stroke, gas pre-flow starts when the welding torch trigger switch is
pressed. The welding process then starts. Releasing the trigger switch stops
welding entirely and starts gas post-flow.
4-stroke
With 4 stroke, the gas pre-flow starts when the welding torch 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, then the ending arc is generated
using the ending arc voltage and current. Releasing the trigger switch stops the
welding and gas post-flow starts.
4-stroke repeat
When the torch trigger switch is pressed in, the gas flow starts and an arc is
generated. When the trigger switch is released the arc generation is locked.
When the trigger switch is pressed in again, the ending arc is generated using
the ending arc voltage and current. When the switch is released again, the
welding stops. When the trigger switch is pressed in again within two seconds
and holding it, welding with repeated ending arc starts. When the switch is
released the repeated ending arc stops. If the switch is not pressed in again
within 2seconds, the welding with repeated ending arc stops.
2-stroke mode (welding without ending arc)
