25KVA-220KVA Stationary Spot Welder, Projection Welder
HERON Intelligent Equipment Co., Ltd. provides opportunities for growth and development to our partners. MFDC 25KVA-220KVA Stationary Spot Welder
MFDC 25KVA-220KVA Stationary Spot Welder and projection welder B series

Application
MFDC stationary spot welder and projection welders are mainly used for hardware welding and copper wire welding of low voltage electronic switch components.
Feature
- The resistance welding machine power ranges between 25KVA to 220KVA.
- The maximum short circuit current of our welding machine ranges between 15.5KA to 40KA.
- At an air pressure of 6bar, the welding pressure of our welder reaches up to a range of 480~15000N.
- The effective throat depth is 230mm.
- One-stroke cylinder is standard configuration for our welding machine. However, because a double stroke cylinder and servo electric cylinder are both compatible with the welding equipment, customers can choose these cylinder options.
