How about Shenzhen Weichuang cold welding machine?

The working principle of cold welding machine is to discharge by capacitor, which can accurately control the current. Compared with other welding machines, it has less heat when working, and the deformation of thin plate can be controlled when welding. When welding, the white solder joint makes the welded plate beautiful, and there is no color difference or little color difference when welding or repairing, especially for some fine workpieces, because of their minimal heat output, they are not easy to deform and bite after welding, and the precision and strength of repairing are very high.

There are many products in cold welding machine, such as precision welding repair machine, electric spark surfacing repair machine, thin plate welding machine, etc.
