Special 4 Stages ( Automatic ).
This function can be used with:
- 4 stages double level current
- pulsed 4 stages
- 4 stages double level pulsed current
It allows the crater current to be maintained (CrC) when
the welding process is over until the welding torch trigger
is pressed. In order to obtain this 4 stages the fi nal crater
fi ller function (CrA) must be ON and the crater current
(tCr) must be 0.0.
Welding starts when the welding torch trigger is pressed
and immediately released. Starting current is the current
controlled by parameter SC, the up slope follows and the
welding current is reached.
To stop welding the operator presses the welding torch
trigger and keeps it held down, the machine then follows
the slope down and reaches the crater current (CrC), this
value remains active until the welding torch trigger is re-
leased Fig. ( 2 ).

rent (automatic).
Before lighting the arc set the two current levels:
First level: Press button P until led T glows and then use
knob AA to set the main power
Second level: press button P until led V glows and use
knob AA to set the main power.
After the arc is lighted, the current begins to increase
over the previously set "slope up" time (led S on), until it
reaches the value set by means of knob AA. The LED T
lights and the display O shows it.
Should it be necessary to reduce the current during
welding, without shutting off the arc (for instance when
changing the welding material or working position, mo-
ving from horizontal to upright, etc.), press and imme-
diately release the torch trigger, the current reaches the
second set value, the led V lights and the led T shuts off.
In order to go back to the previous main current, repeat
the same torch trigger pressing and releasing action, the
