Royce Welding 300s

The Royce Welding Machine 300S (often listed as MMA‐300S or RAC‐300S) is a portable inverter arc welder designed for MMA (Manual Metal Arc) / stick welding. It uses modern IGBT inverter technology, making it more energy‐efficient, lightweight, and easier to use than old transformer‐style welders. Key Specs (Typical for Royce 300S) Power: ~220 – 230 V AC (single‐phase) Current Range: ~~20 – 300 A (adjustable) Accepts Electrodes: ~1.6 mm – 5.0 mm rods Inverter Technology: IGBT for stable arc and high efficiency Duty Cycle: Often advertised as high enough for extended work sessions without stopping Portable: Lightweight and typically includes a handle/strap for carrying
