K1278-14 - Lincoln SAE-400 Perkins Diesel Engine Driven Welder

Industrial Grade Power and Reliability

The Lincoln Electric SAE-400 (K1278-14) represents the pinnacle of heavy-duty industrial welding solutions. Designed for the most demanding environments, this engine-driven welder is powered by a robust Perkins 404D-22 liquid-cooled diesel engine. With 64.4 horsepower, the engine provides ample torque and stability to maintain consistent welding output even under heavy load. The unit is encased in a rugged, heavy-gauge steel housing designed to withstand the physical abuse typical of offshore platforms, pipeline construction sites, and large-scale structural fabrication yards.

One of the defining characteristics of the SAE-400 is its impressive duty cycle. Rated at 400 amps at 100% duty cycle, this machine allows operators to weld continuously without fear of overheating or thermal shutdown. For peak demands, it can deliver up to 500 amps at a 60% duty cycle, providing the headroom necessary for large diameter electrodes and air carbon arc gouging applications. The integrated 29-gallon fuel tank ensures long operational run times, reducing downtime associated with refueling and increasing overall job site efficiency.

Beyond its primary welding capabilities, the SAE-400 serves as a mobile power station. It provides 3,000 watts of AC auxiliary power via Euro and NEMA receptacles, delivering both 120V and 240V output. This feature allows crews to operate grinders, lights, and other essential power tools directly from the welding unit, eliminating the need for separate generators. Maintenance is streamlined thanks to the industrial-grade Perkins engine, known globally for its longevity and serviceability. For fleet managers and industrial buyers, the SAE-400 offers a compelling return on investment through its durability, fuel efficiency, and versatile performance profile.
