5.2.2 2 cycle operating mode with slope-down (Slope)
2 cycle operating mode procedure with slope-down (Slope):
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 expired, the welding current is changed from
the Hotstart value to the value set for welding over the duration of the
Hotstart slope time.
2. cycle Release the torch trigger
For the duration of the slope-down time, the welding current is reduced to
the value set for the slope-down current
The wire feed stops after the slope-down time has expired
Freeband and freeband control are executed
The inert gas is switched off after the gas post-flow time has expired
