1- Place the torch in welding position above the metal with a gap of roughly 2-3
mm.
2- Press the torch trigger (the arc starts without contact using High Frequency
impulsions).
3- The initial welding current circulates, the welding carries on according to the
welding cycle.

1- Position the torch nozzle and the tip of the electrode on the piece of metal and
press the trigger.
2- Position the torch to create a gap of roughly 2-3 mm between the tip of the
electrode and the metal. The arc starts.
3- Put the position back into position to start the welding cycle.
WELDING PROCESSES TIG STD or PULSE
• TIG STANDARD
This welding mode in direct current (DC) is designed for ferrous metal such as steel, stainless steel or even copper and its alloys.

• PULSE TIG
This pulse welding mode create alternative high current pulses (I, welding pulse) and low current pulses (I_cold, pulses to cool the piece). This pulse
mode allows to assemble pieces while while keeping the machine cooler.
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 succeed each other
