• TIG DC 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 is used to prevent the machine from overheating when assembling pieces together.
Example :
The welding current I is set to 100A and % (I_Cold) = 50%, i.e. a cold current = 50% x 100A = 50A.
F(Hz) is set to 10Hz, the signal period will be 1/10Hz = 100ms -> every 100ms, one pulse at 100A then another at 50A will follow one another.
