Product Overview The defining feature of this sink seam welding machine is its specially designed large flat copper platform electrode. The increased contact area ensures stable, uniform conductivity and minimizes heat distortion on thin stainless steel sheets from 0.8 mm to 2.0 mm, resulting in flat, dimensionally accurate sink bowls. Key Features Large Flat Copper Platform: A generously sized copper electrode spreads current evenly across the workpiece. Stable Uniform
