increase over the previously set "slope up" time (led S lit),
until it reaches the value set by means of the knob O. The
LED X lights and appears on the display P.
Should it be necessary to reduce the current during welding,
without shutting of the arc (for instance when changing the
welding material or working position, moving from horizontal
to upright, etc....), press and immediately release the torch
trigger: the current will switch to the second value selected,
the LED W will light and X will go off.
To return to the previous main current, press and release the
torch trigger once again. The LED X will light, and the LED W
will go off. To stop welding at any time, simply hold down the
torch trigger for more than 0.7 seconds, then release. The
current begins to fall to zero within the previously set "slope
down" time interval (LED U lit).
If you press and immediately release the torch trigger during
the "slope down" phase, you will return to "slope up" if it is set
to greater than zero, or to the lesser current value of those set.
NOTE: The expression "PRESS AND IMMEDIATELY
RELEASE" refers to a maximum time of 0.5 seconds.

lows:
Press the selector switch R until the LED X lights, then adjust
the maximum current value using the knob O.
Press the selector switch R until the LED W lights, then
adjust the intermediate current value using the knob O.
Press the selector switch R until the LED AP lights, then
adjust the starting current value using the knob O.
The operating logic is the same as previously described for
welding with dual current level (LED G).
I - special program LED
To light the arc, press the torch trigger and hold it down; the
current begins to increase at a fixed rate. If the torch trigger
is released, the current immediately rises to the welding
value (LED X). To stop welding, press the torch trigger and
hold it down; the current begins to drop at a fixed rate. The
current immediately returns to zero if the trigger is released.
L - spot-welding LED (Manual).
After selecting the welding current (LED X) and the spot
welding time (LED T) using the selector switch R, set the val-
ues using the knob O.
This welding mode is to be used only if start-up with high fre-
quency is selected (LED D lit). In this welding mode, the
operator presses the torch trigger, the arc lights, and after
