Sunstone Orion mPulse PRO Pulse Arc Welder
The Orion mPulse PRO is a practical upgrade for jewelers or studios that need more capability than an entry-level system without moving into the size or cost of a full arc welder. Built on the familiar mPulse platform, the PRO version increases the available power to 60 joules, giving users a wider range of applications and noticeably stronger weld performance, especially when working with thicker material or more demanding joints.
One reason we often recommend the mPulse PRO is its straightforward operation. The 5-inch touchscreen keeps adjustments simple, and the digital energy control allows quick, precise changes without a learning curve. For detailed work, energy below 15 joules can be adjusted in 0.5-joule increments, which offers good control for prong retipping, small repairs, and delicate components. Above 15 joules, the welder moves through whole-joule steps, making it easy to jump into higher power when needed.
The PRO includes an integrated articulating arm, stylus, and 5x optics, so it arrives ready for bench use with minimal setup. The compact unit can be positioned horizontally or vertically depending on the layout of your workspace. Front-facing ports streamline cable connections, and Tru-Fire™ software helps reduce misfires for a smoother welding experience.
Shops that already own a laser welder often add the mPulse PRO as a secondary system. Pulse arc welding is generally stronger on reflective metals — particularly silver — and many users prefer the deeper penetration it offers for certain repairs. It’s an affordable way to expand capability while keeping equipment size manageable.
Overall, the mPulse PRO is a solid choice for jewelry studios, metalsmiths, repair shops, and technical environments that need more power than the base mPulse but don’t require a full high-end arc welder. It offers a strong balance of portability, performance, and ease of use.
