5.2.1 2 cycle operating mode
The 2 cycle mode is recommended for fast, controlled tacking and manual spot
welding.
1. cycle Operate the torch trigger
The inert gas solenoid valve opens
After the set gas pre-flow time has expired the power unit is switched on
Welding voltage on
Wire feed runs at the initial wire feed speed
Arc is ignited after the welding wire contacts the workpiece
The feed switches to the set wire feed speed of the welding process
The welding current flows with the set Hotstart value
After the Hotstart time has elapsed, the welding current is adjusted from
the Hotstart value to the welding current over the duration of the Hotstart
slope time
2. cycle Release the torch trigger
Wire feed stops
Freeband and freeband control are executed
The inert gas is switched off after the gas post-flow time has expired
