**Features of the Machine**
The machine is available in both Transversal Seam Welding and Longitudinal Seam Welding models. One machine can be converted between these two modes by simply adjusting the direction of the upper seam wheel head and swapping the lower welding head and arm within minutes. This flexibility makes it ideal for a wide range of applications.
It features a driven head and a free-moving head, ensuring that both seam wheels maintain the same tangential speed for consistent weld quality. The design allows for efficient operation and high productivity.
This welding machine is widely used in industries such as hardware, appliances, automotive, metal manufacturing, and the production of pots, cans, fuel tanks, and other metal components.
