4.1.3 Operating mode Super-4-cycle
Operating mode Super-4-cycle is provided for longer standard manual
welding tasks. The operating mode allows working with different main
parameters for the so-called power continuation. The power continuation
is ensured by shortly pressing the torch trigger.
1st cycle --> Press and hold torch trigger
• Solenoid valve for shielding gas opens
• Welding voltage is applied on wire electrode
• Wire drive unit starts with reduced speed (inching-in)
• Arc ignites, welding current flows
• Wire drive unit switches to the preset speed
2nd cycle --> Release torch trigger
• The start program is executed with the adjusted parameters and then
switches via a programmable time function ("Upslope") to the main
program.
If the start time in the program menu is set to "Torch", releasing the torch
trigger switches to the main program.
(Optional) Power continuation --> Tap torch trigger
• Depending on the configuration of the "Step modulation" and "Num-
ber of steps" parameters, the power and wire feed speed are increased
or reduced with each press of the button on the torch. You can find
additional information in the chapter "4.2 Configuration of character-
istic curve".
3rd cycle --> Press and hold torch trigger
• A time function (Downslope) switches from the main program to the
end program and the end parameters are executed.
4th cycle --> Release torch trigger
If the end crater filling time parameter is set to "Torch", the end parame-
ters are not executed until the torch trigger is released.
• Wire drive unit stops
• Weld voltage switches off after expiration of the "burnback time"
• Arc extinguishes
• Solenoid valve closes after expiration of the "gas post-flow time"
