TIG DC WELDING
TIG DC - Standard
The TIG DC Standard welding process allows high quality welding on most ferrous materials such as steel, stainless steel, but also copper and its
alloys, titanium... The many possibilities of current and gas management allow you to perfectly control your welding operation, from priming to final
cooling of your welding rod.

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 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 10Hz, the signal period will be 1/10Hz = 100ms -> every 100ms, one pulse at 100A then another at 50A will follow one another.
