55KVA-440KVA Medium Frequency Electric Welding Machine (Stationary Spot Welder, Projection Welder)

Low configuration medium frequency resistance welding machine MFE series
  • Medium frequency spot welder and projection welder 55KVA/110KVA
  • Medium frequency spot welder and projection welder 165KVA / 220KVA / 250KVA / 440KVA

Application
Low configuration medium frequency resistance welding machines are primarily used for spot welding and projection welding processes, such as the welding of carbon steel, stainless steel, aluminum, copper and other alloys.

Feature
1. The resistance welding machine power ranges between 55KVA to 440KVA.
2. The maximum short cut current of our welding machine ranges between 18KA to 60KA.
3. At an atmospheric pressure of 6bar, the welding pressure of our welder ranges between 2510N to 15000N.
4. A circular shaft guiderail pressure welding head is standard for this type of welding equipment. The effective throat depth is 950mm.
5. A one-stroke cylinder is a standard configuration for our welding machine, however, as a double stroke cylinder and servo electric cylinder are both compatible, customers can choose from those as well.
