DESCRIPTION

Pneumatic AC pulse spot welder utilizes the general mains supply to lower the voltage and increase the electric current. Such kind of low voltage but large current will be transmitted from the electrode to the linked point of two work pieces. On the linkage, due to the resistance of work piece, high temperature will occur so the metal will therefore generates high heat to make the work pieces in molten condition. Thus, the purpose of welding the two work pieces is achieved. It can be used to weld 10mm of iron and metals like stainless steel. Applicable to all kinds of hardware. Powerful and strong welding current and precise current control. In order to welding different thickness of products, conduction angle of silicon controlled rectifier is divided into 1000 parts for asjusting. Using digital integrated circuit control, strong anti-interference ability, stable and reliable work. Control circuit calls the built-in voltage fluctuation compensation circuit, which can guarantee the power supply fluctuation within + 15% range in a timely manner to make current compensation, ensure stable welding current.
