Advantages:
- - Laser welding with coaxial dust removal.
- - Coding indexing plate driven by DD motor, easy to debug, and flexible.
- - Multiple protection functions during the welding process.
- - Eight-position turntable structure, compact and reasonable layout, allowing for continuous feeding without stopping the machine.
- - Integrated welding turntable function, reducing the number of grabs, with minimal displacement and low defect rate.
- - Wide product compatibility, enabling quick product changeover.
