Overview
The Sunstone Pro-S Servo Weld Head is a servo-powered resistance weld head engineered for precision, repeatability, and process monitoring in both automated production environments and advanced tabletop setups. Designed in an opposed configuration, the Pro-S delivers significantly improved control compared to pneumatic weld heads by integrating real-time displacement and force monitoring directly into the system.
With adjustable weld force, precise positional feedback, and automation-ready capability, the Pro-S enables manufacturers to increase process consistency, reduce variability, and improve overall weld quality across demanding industrial applications.

Technology & Performance
The Pro-S utilizes servo-driven actuation to deliver controlled, repeatable weld force with precise positional tracking. Integrated monitoring systems provide feedback on:
-
Applied weld force
-
Electrode displacement
-
Pull position accuracy
This monitoring capability supports higher process validation standards, making the Pro-S ideal for manufacturers requiring documented weld consistency and quality assurance.
Compared to pneumatic weld heads, the Pro-S offers:
