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.
• TACK WELDING
This welding mode also allows for the pre-assembly of parts before welding, but in two stages this time: the first stage uses a pulsed DC current
which concentrates the arc for better penetration. This is then followed by the second stage where a standard DC current is used to widen the arc and
therefore the weld pool to secure the weld point.
The variable times of the two welding stages allow for better reproduction and non-oxidised weld points.
• E-TIG WELDING
This mode allows for constant power welding by measuring arc length variations in real time to ensure consistent bead width and penetration. In
cases where the assembly requires careful control of the welding energy, the E-TIG mode guarantees that the welder will respect the welding power
regardless of the torch's position in relation to the workpiece.
