The Ralli Wolf RA30D is a high-capacity 315 Amps digital ARC welding machine built for heavy-duty industrial and structural welding applications requiring power, precision, and reliability. Backed by Ralli Wolf's 60+ years of manufacturing expertise, this ARC series welder is engineered to deliver consistent, high-quality welds across single-phase and two-phase power configurations.

The RA30D comes packed with professional-grade features, including Voltage Reduction Device (VRD) technology for enhanced operator safety, Arc Force and Hot Start functions for easier arc initiation and improved welding on difficult materials, and precise ARC control for stable, consistent performance. Its high penetration capability makes it well-suited to thicker sections and demanding structural welds, while built-in ARC stability ensures smooth, uninterrupted operation throughout the welding process.

Designed for flexibility, the RA30D operates on a 1Ph-230V or 2Ph-415V input supply at 50/60Hz, adapting easily to varying power conditions found on industrial sites. With an output current range of 20-315A and a digital display for real-time monitoring, operators get precise control over welding parameters for a wide range of jobs. Despite its high power output, the machine remains relatively light and portable at 8.5 Kg, supporting welding rod sizes from 1.6mm to 3.15mm.

Built to an IP21 housing protection grade with Class F insulation, the RA30D is designed for durability in demanding work environments. Manufactured to ISO 9001:2015 quality standards, the Ralli Wolf RA30D is an excellent choice for professionals who need a powerful, feature-rich digital ARC welding machine for serious industrial welding work.
