B) 4 TIMES CYCLE (2ND LEVEL)
Pressing the button of the torch the 100 milliseconds fixed pre-gasi-
fication time starts (*) after that the LIFT ARC function or the High
frequency ignition becomes available.
The ignition of the TIG arc occurs at a current value same as the
20% of the set value and remains at that value until the button of
the torch is released (*).
When the button of the torch is released the output current re-
aches the set value showed on the digital tool. Pressing again the
button of the torch for over 300 milliseconds, the decreasing current
phase starts which will bring the output signal back to the 20% of
the set value (*).
The current remains at 20% (*) of the set value until the button of
the torch is released; at this point the post-gasification phase starts
(*) with the automatic setting of the post-gas time in function of the
welding current and of the welding time.
See page 16 for predefined POST GAS time modification on HF
series.
2nd LEVEL function: during the welding phase, it is possible to
decrease the value of the welding current up to 50% using the
“2ND LEVEL” (See Fig. 3 between point A and point B).
This function is activated by pressing and releasing the button
of the torch for a period of time lower than 300 milliseconds.
(*) Adjustable on INOXA HFP series
