Seller 300SR Inverter Welding Machine

The 300SR Welding Machine is a high-performance inverter-based welding unit designed for industrial and heavy-duty applications. Operating on a standard AC 220V power supply, it delivers a no-load output voltage of 60V, ensuring reliable arc initiation and stability. With a maximum input power of 11.6 kVA and a maximum input current of 53A, it offers robust performance even under demanding conditions.

The machine is capable of delivering up to 300A welding current at a 32V output voltage during minimum duty cycle operation, making it ideal for welding thick materials and continuous operation. Its rated input current is 41A, and the unit achieves a high efficiency of 83%, helping to reduce power consumption and operational costs.

Designed with durability and safety in mind, the 300SR features an IP21S protection class, providing limited protection against dust and vertical water drops. It also incorporates a fan cooling system to maintain optimal operating temperatures and ensure consistent performance during extended use.

With a power factor of 0.7, the 300SR minimizes reactive power loss, contributing to a more efficient energy usage profile. Whether used in workshops, construction sites, or fabrication units, this welding machine is built to deliver high output, reliability, and long service life
