Lincoln Idealarc DC-1500 Submerged Arc Welder

Product Overview
The Lincoln Idealarc DC-1500 is a high-performance, industrial-grade DC arc welding power source built for demanding automated welding applications where consistency and reliability are critical. Offering both constant voltage and constant current configurations, this versatile unit delivers exceptional arc characteristics across submerged arc and flux-cored welding processes, ensuring superior weld quality and productivity on a wide range of materials and joint types.

Engineered for seamless integration with Lincoln automation systems, the DC-1500 works perfectly with NA-3 and NA-5 automatic wire feeders or the LT-7 tractor. Its single-range output control potentiometer enables precise adjustment across the entire output range, while the process mode selection switch allows quick configuration for different welding procedures. This combination of versatility and user-friendly controls makes the DC-1500 ideal for manufacturing environments requiring multiple welding processes with minimal operator intervention.

Built to endure harsh industrial environments, the DC-1500 features solid-state circuitry, fan cooling, electronic monitoring, and line voltage compensation (±10%) to maintain consistent weld performance. Enhanced protection for windings and rectifiers ensures reliable operation even in moisture-prone or corrosive conditions. The system also includes eight-amp fuse-protected 115V auxiliary power for wire feeders. Backed by Lincoln’s robust warranty—three years on parts and labor plus a seven-year warranty on the power rectifier—the DC-1500 exemplifies Lincoln’s commitment to quality, reliability, and long-term performance.
