Royce Welding Machine 300/300s Royce Welding Machine

Input voltage: 220–230 V AC, single phase (standard mains) Frequency: 50–60 Hz Input capacity: ~8.7 kVA Welding current range: 20–300 A (stepless adjustment) Usable electrode sizes: 1.6 mm – 5.0 mm rods Working duty cycle: Claims up to 100 % at normal ambient temps, around 60 % at full current in hot conditions (40 °C) — meaning it can run for extended periods if cooled properly. Technology: IGBT inverter — improves efficiency and arc stability compared to old transformer welders. These specs make it a true MMA stick welder capable of handling medium-to-thicker steel work — thicker than what small 160–200 A units can handle.
