GYS TITANIUM 400 AC/DC Mode D'emploi page 33

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.

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 AC WELDING
TIG AC - Standard
This TIG AC - Standard welding mode is dedicated to welding aluminium and its alloys (Al, AlSi, AlMg, AlMg, AlMn...). Alternating current allows the
pickling of aluminium essential for welding.
