Equipment functions & components
- AC/DC TIG welding -A alternating current (AC) and direct current (DC). Welding of almost all metals, such as steel, stainless steel, aluminum, copper and many more.
- 2 in 1 combination unit - TIG & MMA welding is possible up to 200A.
- IGBT Technology - Latest and most advanced transistor technology enables high performance welding! No transformer, no MOSFET, state of the art IGBT!
- Lightweight & compact design - only 11.5 kg weight and dimensions of 455 x 220 x 370 mm. Inovative IGBT transistors save space and weight compared to old MOSFET technology. No more heavy carrying!
- HF ignition - enables non-contact ignition and provides much better welding results. No LIFT ARC, no strike ignition!
- Highest Efficiency & Power - Single phase AC power (230V) powers 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 for maximum power retrieval.
Device Features & Benefits
- 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. Some functions, such as current reduction, are only possible in 4T.
- Current reduction - prevents the formation of shrink marks (end craters) at the end of the weld.
- Gas pre-run and gas post-run (TIG) - protect the tungsten electrode from excessive wear and protect the weld seam from oxidation. The parameters can be set individually and separately. They specify how long gas should flow before and after ignition.

AC - Balance (TIG) – is a variable setting between breaking the oxide layer (-) and deeper penetration (+). This helps to influence properties of different materials and alloys.
-
Hotstart – Automatic voltage increase upon the start for better ignition results.
Anti-stick - Automatic shutdown of the welding current in case of sticking of the electrode which allows an easy removal. It also prevents annealing of the electrode. - TIG (Tungsten-Inert-Gas) – Inert gas welding with inert / inactive gases such as Argon 4.6 (99.996%). An arc is created in an argon bell between the tungsten electrode and the workpiece. This melts the material and any filler material that is supplied. A weld seam is created.
- MMA / Stick electrode welding– is a universal welding process. No protective gas is needed and can therefore be used flexibly anywhere.
-
Note:
- The unit is not intended for use in residential areas where power is supplied by a public low-voltage power supply system. It may be difficult to ensure electromagnetic compatibility in these areas due to both conducted and radiated interference.
