Application
High configuration MFDC 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.

Features
  • The resistance welding machine power ranges from 220KVA to 880KVA.
  • The maximum short circuit current from 40KA to 110KA.
  • At an air pressure of 6bar, the welding pressure of our welder ranges between 10000~24000N.
  • A rhombus roller ram is a standard configuration on this type of welding machine.
  • The effective throat depth is 950mm.
  • A one-stroke cylinder is a standard configuration for this welding machine, though a double cylinder and servo electric cylinder are also compatible with our welding equipment. These two cylinders are optional choices.
