To exit the setting phase, hold the WELDING PARAMETERS SE-
LECTION key (T10) down for about 1 second.
2B) FAST PULSE
TIG pulse welding with manual setting of parameters.
WARNING: This can only be programmed when the TIG DC with
HF ignition or TIG DC with "Lift" type ignition weld-
ing processes are used.
Press the PULSE key (T5) until the requited pulsation
is active.
Press the WELDING PARAMETERS SELECTION Key
(T10) a number of times to set the following (in addi-
tion to the WELDING PARAMETERS defined as be-

To exit the setting phase, hold the WELDING PARAMETERS SE-
LECTION key (T10) down for about 1 second.
2C) ULTRA FAST PULSE
TIG pulse welding with manual setting of parameters.
WARNING: This can only be programmed when the
TIG DC with HF ignition or TIG DC with "Lift" type
ignition welding processes are used.
The possibility of using pulsation frequencies that are
not as high, up to 2000 Hz, ideal for welding minor
thicknesses, makes it possible to achieve a great re-
duction in the arc cone and the area thermally altered,
with a more stable, concentrated arc and an increase
in weld penetration and speed.
