5.2.4 4 cycle operating mode with slope-down (Slope)
4 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
2. cycle Release the torch trigger
The welding current is changed from the Hotstart value to the value set
for welding
3. cycle Operate 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
4. 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
