Royce Tig MMA-450 Welding Inverter

The Royce TIG MMA-450 is a portable inverter welding machine designed for both MMA (stick) welding and TIG welding tasks — making it versatile for general metal joining, fabrication, and workshop use. It uses inverter technology to provide efficient arc performance with smoother, more stable output than older transformer welders.

⚙️ Key Features

• Dual Welding Processes:
  • MMA (Manual Metal Arc) — for traditional stick welding
  • TIG (Lift-Arc TIG) — for clean, precise welds (especially on thinner metal)

• Stepless Current Control:
  Smooth, continuous adjustment of welding current to suit different plate thicknesses and electrodes.

• Inverter Technology:
  Efficient IGBT-based inverter design means lower power consumption, a more stable arc, and lighter weight compared with old-style transformer welders.

• Low Power Requirement:
  Runs on standard single-phase 220–230 V AC mains, 50–60 Hz — ideal for most workshops and sites.

• Wide Current Range:
  Variable welding current from 20 A up to ~450 A (max output rating); suitable for light and heavier welding jobs.

• Electrode Compatibility:
  Accepts MMA electrodes roughly 1.6 mm to 5.0 mm in diameter.

• Protection & Durability:
  Designed with overload protection and a protection class around IP21S, meaning basic resistance to dust/splashes.

• Lightweight & Portable:
  Compact size and manageable weight (often ~10 kg) make it easy to move around a shop or job site.
