Welding Current:
- When Welding Mode is selected, Welding
Current Light (D) is on.
- Push or rotate the Welding Parameters'
Regulation Knob (6). The Light (D) blinks.
- Set Welding Current.
- Push again the Welding Parameters' Re-
gulation Knob (6) to confirm the set current.
The LED (D) is ON. To adjust again the wel-
ding current, push once again the Regulation
Knob (6), the LED starts blinking. If set current
