Device Funktions & Components
- DC TIG welding – Direct current (DC). Welding of almost all materials such as steel, stainless steel, copper, brass and many more.
- 2 in 1 combined device – TIG and MMA welding up to 200A.
- Extensive pulse function – TIG PULSE - Prevents the burning of materials and reduces deformation due to heat, particularly suitable for welding thin plates, the material of which may be heated only slightly. Adjustable parameters are: basic current, peak current, pulse frequency, long and short pulse.
- 2T/4T (TIG) – determines the control of the operating mode and provides 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 a single press and release of the button. After pressing and releasing again, the ignition is stopped.
- Down slope – prevents voids (end craters) at the end of the weld.
- Gas post flow (TIG) – protects the tungsten electrode against excessive wear and protects the weld from oxidation. The parameter can be set individually and separately. It indicates how long after ignition ends gas should flow.
- 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 purchase!
Device Features & Benefits
- IGBT Technology – latest transistor technology enables highest power and a duty cycle of 60% at full power. No transformer, no MOSFET, modern IGBT.
- Lightweight & compact design – only 9,7 kg and dimensions of 455 x 220 x 275 mm. Innovative IGBT transistors save space and weight compared to the old MOSFET technology. No heavy carrying!
- High frequency ignition– allows non-contact ignition and ensures a much better welding result.
- Welding current / Basic current - The two rotary knobs “welding current” and “basic current”, two different current intensities can be set for a welding operation between which the welding current always changes.
- Pulse frequency - The pulse frequency determines how often the current changed back and forth between the two set values within a fixed time interval.
- Long pulse - The weld becomes wider, the heat input is higher and the penetration is deeper.
- Short pulse - The weld pool is easier to control and the danger of welding a hole in the sheet is lower.

- Innovative hose package including modified WP-26F torch with flexible head. The welding current is regulated by means of an adjustment wheel installed directly on the torch. The torch is connected to the hose assembly via a ball joint. This enables flexible and easy working.
-
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.

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.
