Stahlwerk SRG 300 Pro

The SRG 300 Pro is a compact electronic weld seam cleaning device designed for the electrochemical cleaning and passivation of weld seams and metallic surfaces. Specifically developed for stainless steel, it removes heat tint, oxide residues, and discoloration from weld seams, resulting in a metallic bright, passivated surface. It is ideal for visually demanding visible seams and components with high corrosion requirements. Unlike traditional pickling methods, the SRG 300 Pro does not use highly aggressive acids such as nitric, hydrofluoric, or sulfuric acid. Instead, it utilizes a suitable electrolyte in combination with a conductive carbon fiber brush, activated by electric current. This creates a controlled, material-friendly cleaning process without mechanical abrasion like grinding, which smooths the surface while simultaneously passivating it. With an adjustable output current of 10-30 A, the cleaning performance can be tailored to the size/area and degree of contamination of the weld seam, from fine heat tints to stronger oxidations. Weighing only about 2.2 kg and featuring compact dimensions, a carrying strap, and a 230-V power connection, the device is perfect for flexible use in workshops, manufacturing, or mobile service applications.
