Functions
- AC/DC TIG welding - welding with alternating current (AC) and direct current (DC). Ideal for almost all metals, including steel, stainless steel, aluminum, copper and many more.
- 2-in-1 combination device - TIG and MMA welding with a maximum output of 200 A possible.
- IGBT technology - The latest transistor technology ensures high performance and efficiency during welding. Space and weight advantages thanks to the elimination of MOSFET technology.
- Lightweight & compact - With a weight of just 13 kg and compact dimensions of 450 x 230 x 415 mm, the device offers high mobility. The modern IGBT technology significantly reduces the weight compared to conventional devices.
- HF ignition - Contactless high-frequency ignition for better welding quality. No lift-arc or brush ignition required.
- Highest efficiency & power - Single-phase AC (230 V) delivers an output power of true 200 A.
- Smart cooling & overheat protection - Integrated overheat protection and powerful cooling ensure safe operation even under high loads.
- Digital display - A new digital display enables precise settings for all welding parameters.
- Remote connection - Additional connection available for the remote control to operate the WP26R hosepack (not included).
- Spot mode - In addition to 2-stroke and 4-stroke, spot mode is now also available.
- 2T/4T (TIG) - Control of the operating mode for extended current flow. In 2T mode, HF ignition remains active as long as the torch trigger is pressed. In 4T mode, the arc is ignited after pressing and releasing the button once and is only terminated when the button is pressed again.
- Current reduction - Prevents the formation of blowholes at the end of the weld seam.
- Gas pre- and post-run (TIG) - Adjustable gas pre- and post-run times protect the tungsten electrode and the weld seam from oxidation and wear.
- AC balance - is a variable setting between breaking up the oxide layer (-) and a 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.
- TIG (Tungsten Inert Gas) - Gas-shielded 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.
- With the integrated clean function, weld seams can be effectively cleaned, passivated and refined. Electrolytic cleaning of weld seams has the advantage that the weld seam is corrosion-resistant after treatment and has a smooth surface.
- Note: The appliance 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.
