Pneumatic butt welding machine, also known as resistance butt welding machine, uses the resistance between the contact surfaces of the two workpieces to instantly pass a low voltage and a large current to make the contact surfaces of the two butt metals instantly heat to melt and fuse. No need to upgrade any solder, high efficiency and low cost.
The butt welding machine adopts high-performance pneumatic components, and the core shaft and guide shaft are all made of stainless steel. The welding controller is controlled by a data integrated control system or a microcomputer resistor controller to set up main parameters such as charging time, welding time, delay, rest, welding current, etc. It can be equipped with double foot pedal, double single pulse, double current Control function, and its thyristor temperature increase supervision function. A variety of welding controllers satisfy different functions and can be used for one machine.
The secondary internal pressure test of the welding transformer is used for forced cooling, and it is made of high-permeability raw materials with a lifting design, low full-load loss, strong and stable output power and long life.
