Sunstone Orion Pulse Arc Welders (150s / 250s)

Overview

The Sunstone Orion Pulse Arc Welders are professional-grade micro TIG (pulse arc) welding systems engineered for controlled, repeatable micro-welding in bench-top and light production environments. Using high-frequency arc pulses, these systems deliver clean, concentrated welds with precise energy control and minimal heat-affected zones, making them well suited for delicate assemblies across jewelry, dental, medical device, electronics, and sensor fabrication workflows.

The Orion lineup includes two primary configurations:

• A 150-joule class model for precision welding from very low energy up to moderate power

• A 250-joule class model for higher-energy applications requiring deeper penetration and larger spot welding

Both options feature advanced digital controls, large full-color touchscreens, and intuitive energy profiles to support consistent results across a wide range of metals and joint types.
