To exit the setting phase, hold the WELDING PARAMETERS SE- LECTION key (T10) down for about 1 second.
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 reduction in the arc cone and the area thermally altered, with a more stable,
concentrated arc and an increase in weld penetration and speed.
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 addition to the WELDING PARAMETERS defined as being
“BASIC”):
