2.1.2 Operating mode 4-cycles
1st cycle --> Press and hold torch button
•
Solenoid valve for shielding gas opens
•
Weld voltage is applied on wire electrode
•
Wire feed starts with reduced speed (inching-in)
•
Arc ignites, weld current flows
•
Wire feed switches to the preset speed
2nd cycle -->Release torch button
•
The start program is executed with the adjusted parameters and then
switches via a programmable time function ("Up-Slope") into the main
program.
3rd cycle --> Press and hold torch button
•
Change from main program to the end program via a time function
("Down-Slope").
4th cycle --> Release torch button
•
Wire feed stops
•
Weld voltage switches off after expiration of the "burnback time“
•
Arc extinguishes
•
Solenoid valve closes after expiration of the "gas post-flow time“
