Advantages and Applications
1. This machine is a specialized seam welding solution for two-piece metal cans and barrels, delivering dense, uniform welds with reliable sealing and strong weld quality, as well as high production efficiency.
2. The device uses copper wire as the middle electrode to prevent electrode damage caused by the galvanized layer, ensuring consistent welding quality.
3. Welding materials: suitable for seam welding galvanized sheet, tinplate, stainless steel, and base iron cold plates. It can achieve high-quality, high-efficiency welding on a wide range of shaped workpieces.
4. Available welding modes: continuous seam welding, pulse seam welding, and intermittent seam welding.
5. Widely used for welding products such as tinplate barrels, paint barrels, chemical barrels, military barrels, flower basket barrels, industrial heartburn pots, gift packaging boxes, car mufflers, vacuum cleaner casings, fire extinguisher boxes, stainless steel soup barrels, solar water tanks, and thin-walled two-piece can containers.
