• L13:
Electrode diameter in TIG AC.
By giving
to the generator the diameter of the torch electrode that
you are using
parameters in the start in AC TIG mode. The diameters
available are: 1,0mm
– 1,6mm – 2,0mm – 2,4mm –
3,2mm
– 4,0mm.
• L14: Slope up time.
This makes it possible to set a
time in which the current is taken from the start current to
the welding current.
• Pre-gas time.
It makes it possible to determine the
length of gas emission before the HF start.
Pre-gas time is adjustable pressing key S2 for 2 seconds
on two-stroke HF (2T-HF) TIG welding.

ELDING
Touch the piece being worked with the electrode of the
torch.
Press (1T) and keep the button for the torch held down.
Slowly lift the torch to strike the arc.
The WELDING CURRENT goes to the value set, carrying
out an ASCENT RAMP if necessary (adjustable time).
