Product Description

High Frequency Circular Spot Welders Seam Welding Machine For Oil Filled

Product Description

Main Functions
The automatic circumferential spot welding machine(Radiator boss stitch welding machine) is one resistance welding equipment for the boss between the Oil filled heater, It is featured with reliable welding, good sealing, high efficiency, low cost, etc. The mainframe comprises the touch screen, PLC control, silicon controlled rectifier (SCR) as the phase switch, with the high-performance components, the stable welding quality, and the overheating, air pressure, water flow and other protection warning functions. 

Process Parameters
The pass rate of oil heater after welding≥95% (Calculated by sets).
