Functions
- 2 in 1 combination unit - TIG & MMA welding is possible up to 200A.
- Integrated electrolyte cleaning function for post-processing, passivation and refinement of welds.
- AC/DC TIG welding - Alternating current (AC) and direct current (DC) enables welding of almost all metals, such as steel, stainless steel, aluminium, copper and many more.
- Innovative hose package including modified WP-26F torch with flex head. The welding current is regulated via an adjustment wheel on the torch.
- The welding torch is connected to the hose package via a ball joint. This allows flexible and easy working.
- Light & compact design - only 11.5 kg weight and dimensions of 455 x 220 x 370 mm.
- IGBT Technology - Latest and most modern transistor technology - Innovative IGBT transistors save space and weight compared to the old MOSFET technology. No more heavy carrying!
- HF Ignition - Enables non-contact ignition and provides a much better welding result. No LIFT ARC, no strike ignition!
Functions
- Highest efficiency & power - single phase AC (230 V) powers the unit and allows a maximum output of 200 amps.
- Smart Cooling & Overheat Protection - State-of-the-art technology, integrated overheat protection and high performance cooling allow maximum power to be accessed.
- 2T/4T (TIG) - Determines mode control and provides advanced control over current flow. In 2T mode, the high frequency (HF) ignition 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, the ignition is terminated. Some functions, such as current reduction, are only possible in 4T mode.
- Current reduction - prevents the formation of shrink marks (end craters) at the end of the weld.
- Gas pre- and post-run (TIG) - Protects the tungsten electrode from excessive wear and protects 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 - The variable current setting allows different material properties to be taken into account during welding.
- Hotstart in ARC/MMA mode - Automatic voltage increase at start for better ignition results.
- Anti-stick in ARC/MMA mode - Automatic decrease of welding current when the electrode sticks allows easy removal of the electrode from the workpiece.
- TIG (Tungsten Inert Gas) - Gas shielded welding with inert/inactive gases such as Argon 4.6 (99.996 %).
- MMA electrode welding / ARC welding - Universal welding process in which an arc melts the electrode and forms a weld. No shielding gas is required.
- Foot pedal - Remote current control via foot pedal. The foot control mode gives you the advantage of being able to regulate the current even during the welding process, giving you different options for carrying out the welding work. The maximum current is set on the unit. The foot pedal is set to 10. When the foot pedal is pressed, the unit ignites with a lower current than is shown on the display. As soon as the foot pedal is fully depressed, the set maximum current is reached. The value on the display does not change during this time. Examples:
- Maximum current display: 100 A / ignition current through pedal: approx. 40 A
- Maximum current display: 150 A / ignition current through pedal: approx. 80 A
- Maximum current display: 200 A / ignition current through pedal: approx. 110 A
Notice: 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.
