1. Stahlwerk AC/DC TIG 200 ST welding machine
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.
2. Stahlwerk CTM-250 ST
The Stahlwerk CTM-250 ST is a versatile 4-in-1 combination welding machine with integrated plasma cutting function. It combines TIG, MIG/MAG and MMA/E manual welding as well as plasma cutting in a compact 200 A inverter and thus covers the most important processes for workshops, assembly companies and ambitious DIY enthusiasts. Numerous welding and cutting parameters can be customised so that you can adapt the device precisely to the material, sheet thickness and work task. In MIG/MAG and cored wire mode, the CTM-250 ST processes solid and cored wire in standard diameters from 0.6 to 1.0 mm (plus 0.9 mm for cored wire) - ideal for processing mild steel, stainless steel and cored wire applications. In DC TIG mode, the inverter enables clean, low-spatter weld seams on unalloyed and high-alloy steels, stainless steel, copper or brass. This is supported by adjustable parameters such as gas feed, gas delay and current increase/decrease. Functions such as hot start and anti-stick function facilitate ignition and prevent the electrode from sticking. Thanks to VRD voltage reduction, overheating protection, intelligent cooling and a robust ST-Guard housing, the device works reliably and safely even in demanding applications. A powerful 4-roller drive ensures a reliable wire feed that transports even thicker welding wires continuously and safely during MIG/MAG welding. Despite its wide range of functions, the device is not suitable for welding aluminium. The integrated 45 A plasma cutter operates with compressed air and achieves cutting capacities of up to approx. 14 mm, depending on the material. This means that not only structural steels, but also stainless steel sheets and metals with rust film or paint can be cut cleanly. The comprehensive accessory package with MIG, TIG and CUT torches, cables and wear parts enables immediate use.

4. Stahlwerk SRG 300 Pro EU
The SRG 300 Pro is a state-of-the-art, compact weld seam cleaning device specifically designed for the electrochemical cleaning and passivation of stainless steel. It effectively removes heat tints, oxide residues, and discolorations from weld seams and metallic surfaces, resulting in a metallic bright and passivated surface. This device is particularly suitable for visually demanding visible seams and components that must withstand high corrosion requirements. Unlike conventional pickling methods that use aggressive acids, the SRG 300 Pro utilizes a special electrolyte in combination with a conductive carbon fiber brush activated by electric current. This allows for a controlled and material-friendly cleaning process without mechanical wear. With an adjustable output current of 10 to 30 A, the cleaning performance can be tailored to the size and degree of contamination of the weld seam. The lightweight device weighs only about 2.2 kg and is equipped with a carrying strap, making it ideal for flexible use in workshops, manufacturing, or mobile service applications.
- Electrochemical cleaning without aggressive acids
- Adjustable output current from 10 to 30 A
- Material-friendly cleaning process without mechanical wear
