• DC TIG welding – DC TIG for welding steel, stainless steel, copper, brass and many other metals. The infinitely adjustable welding current of 10-200 A enables precise adjustment to the material and sheet thickness.
• AC TIG welding – AC TIG specifically for aluminum and aluminum alloys. AC frequency, AC balance and cleaning current can be individually adjusted in order to optimally adapt penetration, seam shape and cleaning effect to the workpiece.
• MMA / MMA welding - electrode welding with a current range of 30-160 A, suitable for many common stick electrodes. Hotstart makes ignition easier, while anti-stick reduces the electrode from sticking to the workpiece.
• Clean mode – Special mode for electrochemical cleaning of stainless steel welds. Tarnish and oxide layers can be removed with a carbon fiber brush and suitable electrolyte; the current strength is selected depending on the degree of contamination and the size of the seam. The necessary carbon fiber brush and the suitable electrolyte are not included in the scope of delivery.
• HF ignition (TIG) – Contactless high-frequency ignition ensures comfortable starting of the arc, protects the tungsten electrode and workpiece and makes working in hard-to-reach areas easier.
• Job memory (0–9) – Up to ten complete parameter sets can be saved directly in the device and accessed at the push of a button – ideal for recurring work and different material/seam combinations.

• 2T/4T operation – Choice of short button press (4T) for long weld seams or held button (2T) for short seams; The start, welding and final current sequences can be controlled particularly conveniently. The device also has a remote connection to operate a WP26FR hose package (not included in delivery).
• Spot welding & repeat function – Spot mode for precise welding of thin sheets with preset spot duration; Repeat function enables recurring welding cycles without completely interrupting the current flow - ideal for even beads and serial work.
• Flexible parameter setting - gas advance (0-2 s), current increase, welding current, current reduction (up to 25 s), final current and gas follow-up can be individually adjusted and allow precise control of the current curve and seam formation.
• IGBT inverter technology – Modern high-performance electronics ensure a compact design, high energy efficiency and stable arcs while reducing power consumption.
• Digital LED color display & logically structured control panel - All important parameters are clearly displayed and can be quickly adjusted with just a few buttons and a central rotary control - ideal for daily use and recurring tasks.
• Four AC waveforms - square, triangular, trapezoidal and sine waves are available and influence penetration, seam width and noise behavior. This means that the welding characteristics can be optimally adapted to the material and application.
• Precise control of the welding curve - Adjustable start, welding and end current, current increase and decrease enable controlled seam runs and avoid end craters, especially in demanding TIG seams.
• Smart cooling & ST-Guard housing - A powerful fan enables long duty cycles, while the robust ST-Guard housing ensures an ergonomic, operationally reliable design and good protection of the components.
• Compact dimensions & low weight - With 12.7 kg and a housing size of 449 × 238 × 437 mm, the device is easily transportable and is suitable for both stationary and mobile use.
•  Note: The device is not intended for use in residential areas where power is supplied via 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.
