CHOICE OF THE TYPE OF IGNITION
TIG HF: non-contact high-frequency ignition of the tungsten electrode on the workpiece.
TIG LIFT : Arcing by contact (for environments where HF is not desirable).
TIG PROCESS SETTINGS
• TIG DC is dedicated to the welding of ferrous metals such as steel, stainless steel but also copper and its alloys,
titanium.
• TIG AC is dedicated to the welding of aluminium and its alloys.
TIG DC WELDING
• 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 ignition to the final cooling of your 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 allows to assemble pieces while while keeping the machine cooler. It is
particularly recommended for assembling thin parts.
(e. g. : 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 10 Hz, the signal period will be 1/10 Hz = 100 ms. Every 100ms, a 100A pulse then a 50A pulse will succeed
each other.
The choice of frequency
• If thin plate without TIG electrodes (< 0.8 mm), F(Hz) > 10Hz,
• If special metal requiring a welding pool sweep for degassing, then F(Hz) 5 < 100Hz.
The frequency adjustment in TIG DC pulsed is done by pressing and releasing the pulse frequency adjustment button
and then operating the main incremental encoder. Frequency value increases when the incremental encoder is operated
clockwise and decreases when it is operated anti-clockwise. This frequency ranges from 0.1 Hz to 900 Hz. The
incrementation step depends on the frequency range :
DC PULSE frequency (Hz)
[0,1 Hz ; 4 Hz]
[4 Hz ; 25 Hz]
[25 Hz ; 100 Hz]
[100 Hz ; 200 Hz]
[200 Hz ; 700 Hz]
[700 Hz ; 900 Hz]
Once the setting has been done, press the frequency setting button again or wait 2 seconds for the power source to
return to the main menu. Pulsed DC welding is available for the "TIG HF" and "TIG LIFT" processes and the "2T" and
"4T" trigger modes.

1. Place the torch in the welding position above the part
(distance of about 2-3 mm between the electrode tip and the
part).
2. Press the the torch trigger (the arc starts without contact
using High Frequency impulsions).
3.The initial welding current flows, the weld will be
continues according to the welding cycle.
1. Position the torch nozzle and the electrode tip on the
workpiece and press the torch button.
2. Tilt the torch until the electrode tip is about 2-3 mm away
from the workpiece. The arc starts.
3. Return the torch to the normal position to start the wel-
ding cycle.
