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. Plug in the TIG torch (ref. 046108) iinto the power source’s EURO connector and the
reverse cable into the negative (-) connector.
• Ensure that the torch is properly fitted and that the consumables (vice grip pliers, collet bodies, diffusers and nozzles) are not worn out.
• The choice of electrode will depend on the current of the DC TIG process.
ELECTRODE SHARPENING
For optimum results, it is advised to use an electrode sharpened in the following way:
d
L
L = 3 x d for a low current.
L = d for a high current

WELDING PROCESSES
• DC TIG welding
Specifically designed for ferrous metals such as steel, stainless steel, copper and its alloys, as well as titanium.
• Synergic TIG welding
No longer based on the selection of a DC current type and the welding cycle settings but intergrates welding rules/pre-installed settings based on
real welding experiences. Therefore, this mode restricts the number of basic, adjustable settings to three: Type of material, welding thickness and
welding position.
ADJUSTABLE SETTINGS
• STANDARD WELDING
The standard DC TIG welding process allows high quality welding on most ferrous materials such as steel and stainless steel, but also copper and its
alloys including titanium. The various current and gas management possibilities allow you to perfectly control your welding operation, from priming to
the final cooling of your weld seam.
• PULSED WELDING
This pulsed current welding mode combines high current pulses (I = welding pulses) with low current pulses (cold I, workpiece cooling pulses). The
pulsed mode allows parts to be assembled while limiting temperature rises and warping. Ideal for on site use.
Example:
The welding current (I) is set to 100 A and % (cold I) = 50%, i.e. cold current = 50% x 100 A = 50.
F(Hz) is set to 10 Hz, the signal period will be 1/10 Hz = 100 ms -> a 100 A pulse every 100 ms then followed by another at 50 A.
• SPOT WELDING
This welding mode allows the pre-assembly of parts before welding. Spot welding can be done manually using the trigger or timed with a predefined
spot welding period. Spot welding allows for better reproduction and non-oxidised weld points.
