AMW-18 Automatic steel chains seal butt welding machine



Salient Features of AMW-18 Automatic steel chains seal butt welding machine

Automatic chain butt welding machine is used to weld low-carbon alloy steel lifting chains by resistance twice current flow method on the basis of German advanced technology, available for manual, inching and semiautomatic operation of nineteen procedures including round chain delivery, rotating, welding, upsetting and burring under encoder and PLC control. It is featured by stable and reliable action, convenient maintenance and complete fault protection, and its main performance is comparable to foreign similar products. The product is mainly used to weld lifting round-link chain as well as skid chain, binding chain and mine chain, with remarkable effect and grade 80 attainable.

  1. Full automatic design with high efficiency.
  2. Easy to operate and adjustment.
  3. Advanced PLC control system optional.

Main parameters of AMW-18 Automatic steel chains seal butt welding machine

DC welding mode adopted is energy-saving and eco-friendly, and greatly improves welding quality and reduces power grid waste. It is an original creation in China as it overcomes the impacts of traditional high-power welding machine to peripheral electric appliances.
