Royce Welding 400s

The Royce Welding Machine 400S is a portable inverter MMA (manual metal arc) welding machine. It uses advanced IGBT inverter technology for stable performance, high efficiency (~85%), low idle power loss, and adjustable current up to around 400 A, suitable for welding steels with stick electrodes. Typical specs include: Input voltage: ~220‐230 V AC, 50‐60 Hz Current range: ~20 – 400 A Electrode sizes: ~1.6 – 5.0 mm Duty cycle: High duty cycle for continuous work in normal conditions
