The STAHLWERK DC TIG 200 ST is a powerful TIG welding machine with MMA/MMA welding function. The advantages of the DC-powered 2-in-1 combination welding machine include its compact design and low weight of only 4.65 kg. In order to achieve optimal welding results, parameters such as gas flow, current increase, current decrease and gas follow-up can be easily adjusted. The gas lead time (0–2 s) determines how long shielding gas flows out and shields the welding area before the arc is ignited. The current rise (0-15 s) regulates the smooth ramp-up of the welding current for a controlled, low-spatter start. By reducing the current (0-25 s), the current is defined and slowly reduced after welding, which supports a clean seam finish. The gas follow-up time (0.1–25 s) allows the protective gas to continue to flow after switching off and protects the hot weld seam from oxidation and contamination. The combination welding machine also has practical functions such as smart cooling and integrated overheating protection. In TIG operation, the 2T/4T function ensures comfortable work. In 2T mode, high frequency (HF) ignition 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 again, the ignition is stopped. The advanced IGBT technology enables maximum performance for TIG and MMA welding with 200 amps. The DC TIG 200 ST IGBT welding machine comes with an extensive accessory package.

Functions

  • DC TIG welding - direct current (DC). Welding of almost all metals, such as steel, stainless steel, copper, brass and much 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 operating mode control and provides advanced control over current flow. In 2T mode, the 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 again, the ignition is stopped.
  • Easily adjustable welding current - the current rise (0-15 s) regulates the smooth ramp-up of the welding current for a controlled, low-spatter start. By reducing the current (0-25 s), the current is defined and slowly reduced after welding, which supports a clean seam finish.
  • Adjustable gas lead time (0–2 s) – determines how long shielding gas flows out and shields the welding area before the arc is ignited.
  • Gas follow-up (TIG) - protects the tungsten electrode from excessive wear and protects the weld seam from oxidation. The parameter can be set individually and separately. It indicates how long gas should flow after ignition.
  • IGBT technology - Latest and most modern transistor technology enables high performance when 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 old MOSFET technology.
  • HF ignition (TIG) - enables contactless ignition and ensures a significantly better welding result. No LIFT ARC, no strike ignition!

Properties & advantages

  • Hotstart - Automatic voltage increase at start for better ignition results.
  • Anti-Stick - Automatic shutdown of the welding current if the electrode sticks allows for easy removal.
  • 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 performance to be achieved.
  • 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 additional material that may be added. A weld seam is created.
  • MMA electrode welding / ARC welding - a universal welding process. An electric arc melts the electrode, forming the weld seam. No protective gas is required.

Note: The device is not intended for use in residential areas where power is supplied from 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.
