K3198-1 - Lincoln Classic 300 HE Diesel Engine Welder K3198-1

Reliable Power for the Pipeline

The Lincoln Electric Classic 300 HE (High Efficiency) is a testament to enduring quality and modern innovation, specifically designed for the rigorous demands of cross-country pipelines, construction, and field erection. For decades, professional welders have relied on the "Classic" series for its pure DC generator output, which provides a distinctively smooth and stable arc that is difficult to replicate with other technologies. The K3198-1 model continues this legacy while integrating a state-of-the-art Kubota diesel engine to address modern requirements for fuel economy and reliability.

At the heart of this machine is a 3-cylinder, water-cooled Kubota industrial diesel engine running at a low 1800 RPM. This lower operating speed not only reduces noise and wear but also contributes to significant fuel savings. Operators can expect approximately 15% fuel savings at 300 amps and up to 30% savings at low idle compared to the previous Classic 300 D model. This efficiency translates directly to lower operating costs over the life of the machine, making it a smart investment for long-term projects.

The welding performance is driven by all-copper windings, which enhance arc stability and ensure consistent heat input. This is critical for code applications where precision is non-negotiable. The machine features five current ranges with overlap, allowing welders to fine-tune the amperage for specific stick welding tasks. Whether you are running Fleetweld 5P+ cellulosic electrodes for root passes or Excalibur low hydrogen electrodes for fill and cap passes, the Classic 300 HE delivers the control you need.

Built for the field, the unit includes a fuel gauge conveniently located on the control panel, ensuring you are never caught off guard by a low tank. Its robust construction is designed to withstand the harsh environments of oil and gas sites, offshore platforms, and heavy industrial zones. When your job demands the traditional feel of a DC generator with the benefits of modern diesel efficiency, the Lincoln Classic 300 HE is the industry standard.
