Overview

The Sunstone CD Single-Pulse Manual (SPM) Series is designed as a straightforward, reliable entry point into precision resistance welding. Using a single-pulse capacitive discharge system, these welders deliver clean, consistent welds for lightweight and low-to-moderate duty applications without the complexity of dual-pulse controls or automation interfaces.

Compact, affordable, and easy to operate, the SPM Series is ideal for labs, educational environments, hobbyists, and small production settings where manual operation is preferred and repeatable weld quality is still essential.
