Welding chuck is a universal and efficient welding equipment that mainly realizes circular seam welding. It can be equipped with welding machines such as argon arc welding machine (wired or unfilled), MIG welding, plasma welding machine, etc.The power supply can be combined with other machines to form an automatic welding system.The welding chuck is mainly composed of a rotating machine head, a displacement mechanism and a controller.The rotating speed of the rotating machine head is adjustable, with an independent speed regulation circuit, and the DIP switch directly presets the weld length.The tilt angle can be adjusted as required, and the welding gun can be lifted and lowered pneumatically.
