High frequency inverter welding power supply enables precise welding by precisely managing and monitoring welding parameters.Inverter welding power supply are widely used on motor industry,battery pack welding,automotive welding(automotive motors, automotive relays, electronic wiring harness connectors, overheat protectors, signal amplifiers, etc.),optical communication device.
Fine Spot Welding Power Supply
When using metal materials to make parts, it is often necessary to cut the materials to a predetermined size and then connect them.The methods of joining materials include mechanical joining by rivets, metallurgical joining by welding, and physical joining by ultrasonic waves. Resistance spot welding is a method of joining metal materials efficiently and economically using metallurgical methods. Therefore, it is widely used in the industry.
We call the resistance welding of precision small workpieces precision resistance spot welding.
Rosen has continuously developed various ultra-small and high-density new precision inverter resistance spot welding power supply, which have replaced the previous metal connection processes such as soldering and riveting.The precision resistance spot welding machine is most suitable for the assembly of small electronic parts with high performance requirements and small parts in the precision machinery industry.
