5.1.2 FUNCTIONING IN 4 TIMES
A Pre-Flow gas time of 100 msec. starts by the first pression of the torch switch; after this time
the ARC ON function is enabled and, when starting the TIG arc, the output current equals 20%
of the value set by the I2 potentiometer (Iweld) and maintains this value until the torch switch
is released.
When releasing the Torch Switch, the welding current reaches the value set by the "I2" poten-
tiometer.

By pressing the torch switch again, the current decreases so as to reach 20% of the current
value set by the "I2" potentiometer.
The slope time can be set by the operator using the selection switch.
The current remains at 20% of I2 until the torch switch is released, then the Post-Flow time
begins and the time is set automatically as function of the welding current and welding time.
If the selection switch is in
slope time at 1 or at 3 sec.
