• 2 STROKE
Press the torch button to perform the welding
cycle starting from INITIAL CURRENT (if a
SLOPE UP is set) and release it to terminate
welding at FINAL CURRENT (if a SLOPE
DOWN is set).
• 4 STROKE
TIG welding is done as follows:
A) Pressing the torch button strikes up the arc
and the current stays at the INITIAL value
B) Peleasing the torch button will start the
SLOPE UP (if present) and the current will
take itself to value I
C) Pressing the torch button will start the
SLOPE DOWN (if present) and the current
will take itself to the FINAL value (crater cur-
rent)
D) Releasing the button will finish the weld
cycle.
• CYCLE
TIG welding is done as follows with this func-
tion on:
• pressing the torch button will strike up the
arc and the current stays at the INITIAL value
• releasing the torch button will start the
SLOPE UP (if present) and the current will
take itself to the PRINCIPAL value (I
• pressing and releasing the torch button for
less than 1 second, the weld current will take
itself to the CYCLE (I
ble to move an infinite number of times
between the two current levels (I
repeating this operation
• pressing the torch button and keeping it
pressed down (for more than 2 seconds) will
start the SLOPE DOWN (if present) and the
current will take itself to the FINAL value (cra-
ter current)
• releasing the torch button will finish the weld
cycle
• SPOT-WELDING
Spot-welding can be done for the set time (in
seconds) by pressing the torch button after
which the arc will automatically switch off
4) The following weld parameters can be set by
pressing the SET button repeatedly
