Automatic High-Frequency Soldering Welder with 6 Stations ZA0-F15015

Features
- Stable Brazing Quality
High-frequency brazing is well suited to large contact areas where high bond coverage is required. Brazed area coverage above 85%, minimal damage to the silver contact surface, uniform filler metal distribution, consistent joint quality throughout production. - Higher Productivity
The six-station rotary table keeps every station working. While one part is being brazed, the next can be loaded and another unloaded, reducing waiting time between operations. Compared with a single-station machine, the production cycle is shortened by more than 30 seconds. - Easy to Operate : The operator only needs to load the parts. The machine completes the remaining steps automatically. Simple operation, lower operator workload, no special welding skills required.
- Water-Cooled Tooling
Internal cooling channels keep the tooling at a stable temperature during continuous operation. After brazing, the part is immediately water-quenched to cool it quickly and reduce oxidation and discoloration. - Faster Product Changeover
The rotary table can hold two tooling sets at the same time, with three stations assigned to each product. Operators simply select the required product on the HMI without changing tooling, making changeover fast and straightforward. - Operator Safety
The working area is enclosed with an aluminum frame and transparent safety panels, providing good visibility while protecting the operator. A safety light curtain stops machine operation whenever the protected area is entered.
