Translation of the original instructions
ELECTRODE WELDING (MMA)
CONNECTIONS AND RECOMMENDATIONS
• Connect the cables, electrode holder and earth clamp in the connectors,
• Respect the welding polarities and intensities indicated on the electrodes boxes,
• Remove the electrode from the electrode holder when the machin is not in use.

TIG WELDING WITH INERT GAS (TIG MODE)
CONNECTIONS AND RECOMMENDATIONS
Connect the earth clamp to the positive connector (+).
Connect the torch to the negative plug (–), the trigger cable and the gas hose.
Ensure that the torch is equipped and ready to weld, and that the consummables (Vise grip, ceramic gas nozzle, collet and collet body) are not da-
maged.
TIG WELDING PROCESSES
A
The grey areas are not useful for this mode.
• TIG DC
This welding mode in direct current (DC) is designed for ferrous metal such as steel, stainless steel or even copper and its alloys.
• TIG DC Pulsed
This pulse welding mode chains high current pulses (I, welding pulse) then low current pulses (I_cold, pulses to cool the piece). This pulse mode
allows to assemble pieces while limiting high temperatures.
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, a 100A pulse then a 50A pulse will succeeed each other.
The choice of frequency
- If welding with TIG electrodes, then F(Hz) synchronised to the gesture,
- If thin plate without TIG electrodes (< 8/10 mm), F(Hz) >> 10Hz
- If special metal requiring a welding pool sweep for degasing, then F(Hz) >> 100Hz
