User manual
TIG DC - STANDARD
• StandardThe 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 keeping the machine cool.
Example :
The welding current I is set to a 100A and % (I_cold) = 50%, thus a Cold current of = 50% x 100A = 50A. F(Hz) is set to 2 Hz, the signal period will
be 1/2Hz = 500 ms. Every 250ms, a 100A pulse then a 50A pulse will succeed each other.
Recommendations:
Choice of frequency:
• If welding with manual filler metal, then F(Hz) synchronised to the filler metal action,
• If thin without filler (< 0.8 mm), F(Hz) >> 10Hz
The pulse frequency is adjusted by pressing and releasing the «F(Hz)» button and then activating the main incremental encoder. Frequency value
increases when the incremental encoder is operated clockwise and decreases when it is operated anti-clockwise. Once the setting is set, it is possible
to press and release again the «F(Hz)» button to re-link the main incremental encoder to the current setting or to wait 2 seconds.
