E type 25/55/110/165/220/250/330/440KVA medium frequency spot /press welder is mainly used in low voltage electrical industry, motor industry, hardware industry, etc. The welding workpieces are starter motor stator, drive motor, plastic case circuit break
Low-voltage DC electricity is converted into high-voltage electricity, with voltages reaching tens of thousands of volts, which breaks through the ionization of air through the spark plug inside the cylinder to generate electric sparks
