SETTINGS
• Standard
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.
• Pulse
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
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.
• Spot-Pulse
This method of welding is used to pre-assemble thin sheet metal workpieces prior to the actual welding process. 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.

T1 - The main button is pressed, the welding cycle starts (Pre-Gas,
I_Start, upslope and welding).
T2 - The main button is released, the welding cycle is stopped
(downslope, I_Stop, Post-Gas).
For two-button torches in T2 only, the secondary button is treated as
the main button.
