K1387-11 - Lincoln Idealarc DC-1000 Industrial Subarc Welder

The Standard for Submerged Arc and Gouging

For professional welders and fabricators dealing with heavy plate, the Lincoln Idealarc DC-1000 is the machine you trust when the job demands serious amperage. It is widely considered the industry standard for submerged arc welding and heavy-duty air carbon arc gouging. With a rated output of 1000 amps at 100% duty cycle, this machine allows you to run large diameter wires and gouging carbons all day long without the machine breaking a sweat. The arc characteristics are legendary—smooth, stable, and consistent, thanks to Lincoln's time-tested solid-state circuitry.

Versatile Control
The DC-1000 puts you in complete control of the welding arc. A mode switch on the front panel allows you to instantly toggle between Constant Voltage (CV) for MIG and flux-cored wire welding, and Constant Current (CC) for submerged arc, stick, and gouging applications. The single-range output control potentiometer makes dialing in your parameters precise and easy. Additionally, the machine features a secondary 500-amp output terminal. This is a critical feature for applications requiring lower currents, as it provides superior arc stability and control that the high-output terminals might not offer at the low end of the range.

Built for the Shop Floor
Lincoln designed the DC-1000 to integrate seamlessly with automatic equipment. It pairs perfectly with the NA-3, NA-5, and LT-7 automatic wire feeders, as well as the LN-series semiautomatic feeders. The front panel includes a terminal strip for easy remote control connections and wire feeder integration. Whether you are welding thick-wall pipe, structural beams, or gouging out welds for repair, the DC-1000 provides the raw DC power and arc quality necessary to produce code-quality work efficiently.
