"150kva stationary spot welding machine"

stationary frequency inverter resistance press projection type spot welding welder machine Resistance Water Refrigerated Spot Welders Product FEATURE This type of AC 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
