Advantages and Applications
1. This machine is a specialized seam welding equipment for two-piece metal cans and barrels, delivering dense and uniform weld seams, reliable sealing, firm welding, and high production efficiency.
2. The device uses a copper wire as the middle electrode to prevent electrode damage caused by the galvanized layer, ensuring stable welding quality.
3. Welding materials: Suitable for seam welding galvanized sheet, tinplate, stainless steel, and base iron cold plates, enabling high-quality and high-efficiency welding for workpieces of various shapes.
4. Capable of 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 hot pots, gift packaging boxes, car mufflers, vacuum cleaner casings, fire extinguisher boxes, stainless steel soup barrels, solar water tanks, and two-piece cans with thin walls.
