Main features:

The frame parts are welded by steel members and finished after eliminating internal stress. They will not deform after long-term use and have a beautiful appearance.

The upper electrode is composed of 24 spot welding electrodes. The whole device adopts PLC + man-machine interface control and modular circuit control to effectively avoid various interferences, so as to achieve various welding control processes, and realize whether each cylinder works and whether each group of parameters are independently adjustable. The lower electrode is composed of two flat electrodes, and the welding is not affected by the change of welding spot spacing (but affected by the change of workpiece shape, so the lower electrode adopts the screw fixation method which is convenient, firm and reliable for disassembly, so as to facilitate the positioning welding of workpieces of other shapes).

The screw driving device can arbitrarily adjust the welding distance between the two groups. In order to meet the welding requirements of customers, the adjustable range is 895-1350mm, and also meet the welding machines of different specifications.

One device can be used as two or more devices at the same time. It not only greatly improves the production efficiency, but also reduces the production cost, so as to improve the market competitiveness of products.

It is widely applicable to the welding of various specifications of similar box workpieces. It is easy to use, simple and adjustable. Therefore, it will have a broad market space.
