Wave Soldering Machine – WSM 350 DF (Finger Type)

Overview of Wave Soldering Machine – WSM 350 DF (Finger Type)

The Wave Soldering Machine – WSM 350 DF (Finger Type) is a next-generation, high-performance dual wave soldering system designed for automatic PCB soldering in modern assembly lines. Unlike manual carrier-type systems, the WSM 350 DF features an automatic chain conveyor with Special Steel fingers, eliminating the need for manual PCB feeding. Simply load PCBs through linking conveyors or inline modules, and the system handles the rest, ensuring faster throughput, reduced labor, and consistent soldering quality.

Built with dual wave solder baths, advanced spray fluxing with large preheater, and an integrated cooling fans, the WSM 350 DF is the ultimate solution for high-volume, lead-free, and defect-free PCB soldering. Its robust design, energy efficiency, and low-maintenance features make it a preferred choice across industries like automotive, consumer electronics, telecommunications, and industrial automation.

Fully Automatic Operation – Chain conveyor with Special Steel fingers ensures seamless inline PCB soldering without manual handling.

Dual Wave Solder Bath with Advanced Fluxing – spray fluxing, preheater, and dual wave solder bath guarantee defect-free solder joints for mass production.

High Reliability & Low Maintenance – Self-cleaning system, lead-free solder compatibility, and robust design deliver long-term performance with reduced downtime.
