PIW 200HD – DC Arc Inverter Welding Machine (200A):
The PIW 200HD is a compact and lightweight DC inverter welding machine designed for general-purpose welding applications such as maintenance work, light fabrication, and home or workshop use. It uses inverter technology to deliver a stable arc while remaining energy-efficient and portable.
It operates on a single-phase 220V power supply and provides an output current range of 20A to 200A, making it suitable for welding mild steel and similar materials. With a 100% duty cycle at 200A, it can run continuously under rated load without overheating.
This model supports electrodes up to 4.0 mm diameter and is built with IP21 protection and Class F insulation, ensuring safe operation in typical working environments. Its relatively light weight (around 10 kg) and compact size make it easy to transport between job sites.
Best suited for:
• Light to medium welding jobs
• Repair and maintenance work
• Portable or on-site welding
PIW 315HD – DC Arc Inverter Welding Machine (300A):
The PIW 315HD is a heavy-duty DC inverter welding machine designed for industrial and high-demand applications. It delivers a higher output range of 20A to 300A, making it capable of handling thicker materials and more intensive welding tasks.
Like the 200HD, it runs on 220V single-phase power, but with a significantly higher rated input current (73A) and 10.2 kVA capacity, enabling stronger and more consistent welding performance. It also maintains a 100% duty cycle at 300A, ensuring continuous operation under full load.
This model supports larger electrodes up to 5.0 mm diameter, making it suitable for heavy structural work. Due to its robust design, it is heavier (around 30 kg) and larger in size, reflecting its industrial-grade capability.
Best suited for:
• Heavy-duty fabrication and construction
• Thick metal welding
• Continuous industrial operations
