Stahlwerk AC/DC TIG 200 Pulse STC/DC TIG and MMA/E-Hand combination inverter | 2T / 4T mode | suitable for thin sheet metal | AC mode for aluminum

Smart cooling & overheating protection – State-of-the-art technology, integrated overheating protection and high-performance cooling enable maximum power to be called up.
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. Some functions, such as current reduction, are only possible in 4T mode.
Current increase/decrease – prevents the formation of blowholes (end craters) at the end of the weld seam.
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.
Innovative hose package including modified WP-26 torch with flexible head. The welding current is regulated via a setting wheel installed directly on the torch. The torch is connected to the hosepack via a ball joint. This enables flexible and easy working.
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.
Remote regulation via the supplied WP26FR torch, the welding current can be conveniently adjusted at any time using the rotary control mounted on the torch.
Welding current / pulse current – The two buttons “Welding current” and “Pulse current” can be used to set two different current levels for a welding process, between which the welding current then always alternates.
Pulse width – The pulse width is used to set how long the welding current assumes the current intensity of the pulse current before it returns to the normal welding current intensity.
Pulse frequency – The pulse frequency determines how often the current strength changes back and forth between the two set values in a defined period of time.
Long pulse – The weld seam becomes wider, the heat input is higher and the penetration is deeper.
Short pulse – The weld pool is easier to control and there is less risk of welding a hole in the sheet.
Hotstart – Automatic voltage increase at start for better ignition results.
Anti-stick – Automatic shutdown of the welding current if the electrode sticks, making it easy to remove.
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 and can therefore be used flexibly at any location
