MAIN - Operating modes
3.3 Super-4-cycle
Operating mode Super-4-cycle is provided for longer standard manual
welding tasks. The detailed operating possibilities are described in chapter
"6. MAIN - Programming" on page 45.
1st cycle --> Press 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 wire 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 "6.2 Parameters in the operating
mode Super-4-cycle" on page 47.
3rd cycle --> Press torch trigger again
• The end crater program is executed with the adjusted parameters.
4th cycle --> Release torch trigger again
• Change from main parameter to the end parameter via a time func-
tion (Downslope), the end parameter time is executed.
• Wire drive unit stops
• Welding voltage is switched off after expiration of the "burnback time"
• Arc extinguishes
• Solenoid valve closes after expiration of the "gas post-flow time"
3.4 Spot welding
The spot function allows spot welding for a defined time. After pressing
the torch trigger, the controller automatically stops the welding process
after expiration of the defined time.
The welding process is immediately stopped if the torch trigger is released
during the spot time.
The detailed adjustment possibilities are described in chapter "6. MAIN -
Programming" on page 45. You can select a spot time between 0…99.9 s.
3.5 External
This function is intended for automated or robotic operation. The various
signals are selected via the automation interface of the welding power
source.
