THUMBWHEEL NAVIGATION
Rotating the thumbwheel allows
- adjustment to the welding current
- to change a parameter of the welding cycle
Pressing the thumbwheel allows
- access to the welding cycle by selecting the first parameter
- access to the parameter settings and confirm the modification
TIG (GTAW) WELDING MODE
INSTALLATION AND GUIDANCE
• DC TIG welding requires a protective gas shield (Argon).
• Connect the earth clamp to the positive (+) plug connector. Connect the torch power cable to the
negative (-) socket, along with the torch button(s) and gas connector(s).
• Ensure that the torch is properly fitted and that the consumables (clamps, collet bodies, diffusers and nozzles) are not worn out.
• The electrode is determined by the welding current of the TIG process.

ELECTRODE SHARPENING
For optimum results, it is advised to use an electrode sharpened in the following way:
d
SELECT IGNITION MODE
Lift: contact ignition (for applications sensitive to HF disturbances)
HF: high frequency ignition without contact between the tungsten electrode and the workpiece.
Touch.HF: time-delayed high frequency ignition after contact between the tungsten electrode and the workpiece

1- Position the torch nozzle and electrode tip on the workpiece and press the
torch button.
2- Tilt the torch until a distance of about 2-3 mm separates the tip of the electrode
and the workpiece. The arc starts.
3- Move the torch to the regular position to start the welding cycle.
3
1- Place the torch in the welding position above the workpiece (distance of about
2-3 mm between the electrode tip and the workpiece).
2- Press the torch button (the arc is initiated without contact using high voltage HF
ignition pulses).
3- The initial welding current circulates, and the process continues as per the wel-
ding cycle.

1- Position the electrode tip on the workpiece and press the torch button.
2- Lift the electrode from the workpiece.
3- After a delay of 0.2s, the arc is initiated without contact using high voltage HF
ignition pulses, the initial welding current circulates and the weld continues accor-
ding to the welding cycle.
