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 - an AC/DC device is required for this.
- 2 in 1 combination device - TIG & MMA welding is possible up to 200 A.
- 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.
- Easily adjustable welding current - the current increase (0-15 s) regulates the smooth ramp-up of the welding current for a controlled, low-spatter start. The current reduction (0-25 s) is used to define and slowly reduce the current after welding, which supports a clean seam finish.
- Adjustable gas lead time (0-2 s) - determines how long shielding gas flows out before the arc is ignited and shields the welding area.
- Gas run-on (TIG) - protects the tungsten electrode from excessive wear and protects the weld seam from oxidation. The parameter can be set individually and separately. It specifies how long gas should flow after ignition.
- IGBT technology - The latest and most modern transistor technology enables high performance welding! No transformer, no MOSFET, state-of-the-art IGBT!
- Lightweight & compact design - only 4.65 kg weight and dimensions of 370 x 145 x 280 mm. Innovative IGBT transistors save space and weight compared to the old MOSFET technology.
- HF ignition (TIG) - enables non-contact ignition and ensures significantly better welding results. No LIFT ARC, no strike ignition!
- Attention - bottle connection: W21.8 x 1/14" - gas cylinders from the Netherlands and Great Britain may have a different connection! Please check the connections for compatibility before purchasing!
Device features & advantages
- Hotstart - Automatic voltage increase at start for better ignition results.
- Anti-stick - Automatic shutdown of the welding current when the electrode sticks, making it easy to remove.
- Highest efficiency & performance - Single-phase alternating current (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.
