Device functions & components
- DC TIG Welding - Direct Current (DC). Welding of almost all metals, such as steel, stainless steel, copper, brass and many more. Note: Not suitable for aluminum - this requires an AC/DC unit.
- 2 in 1 combination unit - TIG & MMA welding is possible up to 200 A.
- 2T/4T (TIG) -determines mode control and provides advanced control over current flow. In 2T mode, high frequency (HF) ignition remains active until the button on the torch is released. In 4T mode, pressing and releasing the button once ignites the arc. After pressing and releasing again, the ignition is terminated.
- Gas follow-up (TIG) - protects the tungsten electrode from excessive wear and protects the weld from oxidation. The parameter can be set individually and separately. It specifies how long gas should flow after ignition.
- IGBT Technology - Latest and most advanced transistors technology enables high performance welding! No transformer, no MOSFET, most modern IGBT!
- Lightweight & compact design - only 7.6 kg weight and dimensions of 390 x 170 x 275 mm. Innovative IGBT transistors save space and weight compared to old MOSFET technology. No more heavy carrying!
- HF ignition (TIG) - enables non-contact ignition and provides much better welding results. No LIFT ARC, no strike ignition!
- Attention - Cylinder connection: W21.8 x 1/14" - Gas cylinders from the Netherlands and the UK may have a different connection! Please check the connections for compatibility before buying!
Device features & benefits
- Hotstart - Automatic voltage increase at start-up for better ignition results.
- Anti-Stick - Automatic shutdown of welding current when electrode sticks allows for easy removal.
- Highest Efficiency & Power - Single phase AC power (230V) supplies the unit and allows output power of true 200 amps.
- Smart Cooling & Overheat Protection - State-of-the-art technology, built-in overheat protection, and high-performance cooling allow maximum power to be retrieved.
- TIG (Tungsten Inert Gas) - Gas shielded welding with inert/inactive gases such as Argon 4.6 (99.996%). An arc is created between the tungsten electrode and the workpiece in an argon bell. This melts the material and any filler material added. A weld seam is formed.
- MMA electrode welding / ARC welding - a universal welding process. An arc causes the electrode to melt, forming the weld. No shielding gas is required.
- Note: The unit is not intended for use in residential areas where power is supplied by a public low-voltage power system. It may be difficult to ensure electromagnetic compatibility in these areas due to both conducted and radiated interference.
