In Manual Welding Mode the unit will weld conti-
(sec)
nuously while the torch trigger is pressed (Welding
ON). Releasing the torch trigger will interrupt welding
immediately (Welding OFF).
4 Stroke
In Automatic Welding Mode the welding process is
performed as follows:
• first torch trigger pression (Welding ON as current
is fed, Slope Up as set till the set current value
is reached)
• first torch trigger release
• second torch trigger pression (Slope down and
Final Current)
• second torch trigger release (Arc OFF and Post Gas)

WAVE BAL.
Corresponds to the Time ON percentage (20% -
80%); adjusting the duty cycle in pulsed mode allows
the peak current keeping for a longer or shorter time.
