Device functions & components
- AC/DC TIG welding - alternating current (AC) and direct current (DC). Welding of almost all metals, such as steel, stainless steel, aluminum, copper and many more
- Plasma / CUT - A plasma jet is generated by means of electricity, which melts the material, which is then removed with compressed air. This allows all conductive metals such as standard steel, stainless steel, copper, aluminum, titanium and many more to be cut precisely and effortlessly.
- Cutting thickness - Depending on the material, cuts of up to 12 mm are possible. Mild steel ST37 up to 12 mm, V2A or V4A up to 8 mm, aluminum up to 5 mm.
- 3 in 1 combination device - TIG & MMA welding is possible up to 200 A, plasma cutting up to 45 A.
- IGBT technology - The latest and most modern transistor technology enables high performance welding! No transformer, no MOSFET, most modern IGBT!
Device features & advantages
- Lightweight & compact design - only 15.65 kg weight and dimensions of 507 x 238 x 437 mm. Innovative IGBT transistors save space and weight compared to the old MOSFET technology. No more heavy carrying!
- HF ignition (TIG) - enables non-contact ignition and ensures a much better welding result. No LIFT ARC, no strike ignition!
- Contact ignition (CUT) - High frequency (HF) contact ignition for first-class ignition behavior. One stroke over the workpiece is enough.
- Cutting current (CUT) - Infinitely variable adjustment from 20 to 45 A.
- Air follow-up (CUT) - After the cutting process is complete, air flows automatically to cool the torch and reduce wear on the nozzle and electrode.

- 2T/4T (TIG) - determines the control of the operating mode and offers extended control over the current flow. In 2T mode, high-frequency ignition (HF) remains active until the button on the torch is released. In 4T mode, the arc is ignited after pressing and releasing the button once. After pressing and releasing the button again, ignition is terminated. Some functions, such as current reduction, are only possible in 4T mode.
- Current reduction (TIG) - prevents the formation of blowholes (end craters) at the end of the weld seam.
- Gas pre-flow and post-flow (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 - is a variable setting between breaking up the oxide layer (-) and deeper penetration (+). This helps to influence the properties of different materials and alloys.
- Hotstart - Automatic voltage increase at start for better ignition results.
- Anti-stick - Automatic shutdown of the welding current when the electrode sticks for easy removal.
- Highest efficiency & performance - Single-phase AC (230V) supplies the device and allows an output power of real 200 amps.
- Smart cooling & overheating protection - State-of-the-art technology, integrated overheating protection and high-performance cooling enable maximum power to be called up.
- TIG (tungsten inert gas) - shielded arc welding with inert/inert gases such as argon 4.6 (99.996%). An arc is created between the tungsten electrode and the workpiece in an argon bell jar. This melts the material and any filler material added. A weld seam is created.
- MMA electrode welding / ARC welding - a universal welding process. An electric arc melts the electrode to form the weld seam. No shielding gas is required.

Note:
The device is not intended for use in residential areas where power is supplied via a public low-voltage supply system. It may be difficult to ensure electromagnetic compatibility in these areas due to both conducted and radiated interference.
