Automatic CNC Double Sides Spot Welding Machine W Transistor Welding Power Supply 

1. System overview:

The double-sides automatic spot welding machine supports breakpoint start, and is equipped with 6000A / 8000A Transistor power supply. It can weld pure nickel sheet less than 0.2mm and steel nickel sheet more than 0.3. Bump welding is required. Double sided automatic welding, high efficiency. Programming is simple. It supports any point programming, array programming and graphic import, and can store 99 groups of programming files. The prediction of welding needle replacement reminds that the welding head adopts water-cooled circulating heat dissipation to effectively reduce the loss of welding needle and improve the welding effect. The self-contained welding current monitoring system can monitor the welding current, with false welding alarm function, and can monitor the welding in real time.

2.Workflow:

Manual discharge of nickel sheet and cell

Clamp into automatic workbench

Programming and debugging setting parameters

Start equipment

3.Equipment layout:

The double-sides automatic spot welding machine is composed of working power supply, working platform, servo motor, operating system, etc.

Manually put the electric core into the fixture and place the nickel sheet; Push it into the automation platform, and then set relevant parameters, arrays, etc. to realize welding. The main components and layout are as follows:
