DN series pedestal spot welder is mainly used for spot welding of low-carbon steel .During the welding process, the pressurzing and resistance welding time are controlled by the welder based on the thickness of the weldments , but in mass production oper-ation, the resistance welding time can also be selected as auto-control .The electrodes of the machine are pressurized before power on so as to ensure the of soldered dots.
This welding machine is applicable for the spot welding of 1.5-2mm steel plates. It is convenient to operate, repair and maintain, and easy to move, as well as low priced , high efficiency and simple structured
