TIG DC WELDING / GTAW
• 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 the priming to
the final cooling of your weld bead.

• 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.
