https://www.ningboxihe.com/products/medium-frequency-welder/ The single-rib brake shoe seam frequency welding machine adopts intermediate frequency welding technology. The intermediate frequency transformer has the advantages of small size, output rectification, beautiful appearance, convenient maintenance and installation, etc. Since the welding power is direct current, the loss in the heating process is small, so as to achieve the effect of saving electricity ( Usually 30% less than ordinary power frequency). The pressurized welding cylinder of the equipment adopts the brand wear-resistant sealing ring, and the double-layer stroke adjustable structure increases the welding stability and shortens the adjustment time for changing the product model.
