Inverter Based ARC Welding Machine — ARC-200A MOSFET

An inverter ARC welding machine is a modern, lightweight, and energy-efficient welder that uses advanced inverter technology to convert AC power to high-frequency DC power for a stable and smooth welding arc. This makes it easier to create strong, high-quality welds compared to traditional transformer-based welders.

PENTAGON inverter welders offer high efficiency, stable arc performance with minimal spatter, and are lightweight and portable. They are designed for industrial use, support a wide range of electrode diameters, and come with features like forced air cooling for continuous operation.

Both are types of inverter technology. MOSFET is a reliable, cost-effective technology used in models like the ARC-200A. IGBT is a newer technology that offers higher power efficiency and is used in models like the ARC-200A RAFEL and the higher amperage machines (325A, 350A, 400A), allowing for more power in a compact size.

Most models, including the 200A, 250A, and 325A, run on standard single-phase AC 220-230V. The ARC-350 DV and ARC-400G models offer dual or three-phase input voltage compatibility (220V/380V), making them suitable for various industrial power grids.

A 60% duty cycle means the machine can weld continuously for 6 minutes out of a 10-minute period at its rated output current without overheating. The remaining 4 minutes are for cooling. This is a standard rating for industrial-grade machines.

The suitable plate thickness varies by model. The ARC-200A models are ideal for 2-6mm, the ARC-250A for 4-8mm, and the higher-end models like the ARC-400G can handle thicknesses up to 20mm, making the range suitable for everything from light fabrication to heavy structural work.

The price for the Pentagon ARC-200A MOSFET model is approximately ₹7,800, and the ARC-200A RAFEL (IGBT) model is around ₹7,200. Prices are subject to change and may vary based on current promotions.

The ARC-200A MOSFET is an excellent choice for small workshops, maintenance and repair professionals, and hobbyists looking for a reliable, cost-effective, and portable machine for welding mild steel and other common metals up to 6mm thick.

The ARC-200A RAFEL is ideal for professionals who need the efficiency and portability of the 200A platform but with the added performance and stability of IGBT technology. It's a great all-rounder for fabrication and on-site repair work.

Choose the ARC-250A GOLD if you need more power for thicker materials (up to 8mm). It's suited for medium-duty fabrication, construction sites, and workshops that require a step up in amperage from the 200A models.

The ARC-325 is designed for heavy-duty industrial applications. With its ability to run on single or double phase power and weld materials up to 12mm, it's perfect for structural steel fabrication, manufacturing, and demanding repair jobs.

The ARC-350 DV is a versatile powerhouse for professionals working in varied environments. Its ability to run on single, double, or three-phase power makes it adaptable, while its 350A output is sufficient for heavy fabrication and welding materials up to 18mm.

The ARC-400G is the top-of-the-line model for the most demanding industrial welding tasks. It requires a three-phase power supply and is built for continuous, heavy-duty work on thick materials up to 20mm, such as in shipbuilding, heavy construction, and manufacturing plants.

The primary difference is the inverter technology. The MOSFET model is a highly reliable, budget-friendly option. The RAFEL model uses more modern IGBT technology, which is slightly more energy-efficient and offers a very stable arc, making it a great value for its price.

Both are excellent industrial machines. The ARC-325 is a solid choice for workshops with consistent power. The ARC-350 DV offers more flexibility with its multi-phase input (1, 2, or 3-phase), making it ideal for job sites where power sources might vary. It also provides a slightly higher amperage for thicker materials.

Upgrade to the ARC-400G when your work regularly involves welding materials thicker than 8-10mm, or if you need to run the machine for long, continuous periods in a heavy industrial setting. The ARC-400G is a dedicated three-phase machine built for maximum power and productivity.
