The Stahlwerk AC/DC TIG 200 ST is a powerful TIG welding machine with MMA/manual welding function. One of the advantages of this AC-powered 2-in-1 combination welder is its compact design and low weight of just 12.7 kg. The AC/DC TIG 200 ST has practical functions such as smart cooling and integrated overheating protection. When TIG welding, the contactless HF ignition enables comfortable working and better welding results. The pre- and post-flow of the welding gas can be individually adjusted to protect the tungsten electrode from wear and prevent oxidation of the weld seam. State-of-the-art IGBT technology enables maximum performance in TIG and MMA welding. Welding aluminium with alternating current is possible in AC mode, as the oxide layer is reliably broken up. The AC/DC TIG 200 ST IGBT welding machine is supplied with a comprehensive accessories package.
