The Balance (%T_AC):
during the positive wave, the oxidation is broken. During the negative wave, the electrode cools and the parts are welded, there is penetration. By
modifying the ratio between 2 alternatives through the balance adjustment, you choose either cleaning or penetration (the default value is 30%).
20%: Max. penetration
The frequency (AC Hz):
the frequency allows you to adjust the concentration of the arc. The higher the frequency, the more concentrated the arc. The lower the frequency
the wider the arc will be.
High
TIG AC - Pulse
This pulsed current welding mode is a combination of high current pulses (I, welding pulse) and low current pulses (I_Cold, part cooling pulse). This
pulse mode allows to assemble pieces while while keeping the machine cooler.
Example :
The I welding current is set to a 100A and % (I_cold) = 50%, thus a Cold current of = 50% x 100A = 50A.
F(Hz) is set to 2Hz, the signal period will be 1/2Hz = 500ms -> every 250ms, one pulse at 100A then another at 50A will follow one another.
