ADJUSTMENT TIPS : The choice of frequency
• If welding with manual metal input, then F(Hz) synchronized to the input gesture,
• If thin without supply (< 0.8 mm), F(Hz) > 10Hz
• Welding in position, then F(Hz) < 100Hz
TIG DC – Fast Pulse
This very high frequency pulsed current welding mode combines high current pulses (I, welding pulse) with low current pulses (I_Cold, part cooling
pulse). Fast Pulse mode allows to keep the arc constriction properties of Pulse mode at high frequencies but still on less unpleasant or even inau-
dible sound frequencies for the welder.
