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 nal 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 predened

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 predened spot welding period. Spot welding allows for better reproduction and non-oxidised weld points.
