ARC 630 Welding Machine – Powerful Dual-Operator Heavy-Duty Welder with Modular IGBT Full-Bridge Technology
ARC 630 DOUBLE OPERATOR
The ARC 630 Welding Machine is engineered for professionals who demand power, flexibility, and durability in industrial welding applications. Built with advanced modular IGBT and full-bridge technology, this heavy-duty welder ensures consistent arc stability, maximum efficiency, and long service life, even under the toughest working conditions.
🔹 Dual-Operator Advantage
One of the most powerful features of the ARC 630 is its dual-operator functionality. The machine can be used by two welders at the same time, each with an independent current setting. In this mode, the power source works as a 400A unit for each welder, allowing different electrodes to be used simultaneously — a true productivity booster for fabrication shops and construction sites.
🔹 Single Heavy-Duty Mode
When operated individually, the ARC 630 delivers its full 630 amps output, making it ideal for:
Heavy rod welding (5mm & 6mm electrodes)
Air arc gouging applications
Continuous industrial-duty cycles
This ensures maximum penetration and strength, making it the go-to machine for heavy fabrication, shipbuilding, and repair work.
🔹 Cutting-Edge Technology
Modular IGBT design → Reliable performance, low power loss
Full-bridge technology → Higher efficiency, smooth welding arc
Industrial-grade cooling system → Longer durability in demanding environments
Versatility → MMA stick welding, heavy electrodes, and gouging tasks
