K841 - Lincoln Electric Undercarriage for Idealarc DC400/DC500 Series - Dual Cylinder Platform

Heavy-Duty Mobility for Industrial Power Sources

The Lincoln Electric K841 Undercarriage is a specialized transport solution engineered exclusively for the Idealarc DC400 and DC500 series welding power sources. Designed to meet the rigorous demands of industrial environments, this undercarriage transforms stationary heavy-duty welders into mobile workstations. The unit features a robust four-wheel base construction that significantly enhances the maneuverability of the equipment, allowing operators to reposition the power source as required by the workflow without the need for forklifts or cranes for minor adjustments.

A key technical feature of the K841 is its integrated dual cylinder platform. Located at the rear of the undercarriage, this platform is sized to accommodate two industrial gas cylinders simultaneously. This capability is critical for multi-process applications or high-volume welding environments where minimizing downtime for cylinder changeouts is a priority. The system includes an upper dual cylinder support structure complete with chains and S-hooks, ensuring that high-pressure vessels remain securely fastened during transport and operation, adhering to safety standards.

The rolling assembly consists of high-quality polyolefin casters, split between 5-inch and 8-inch diameters. This wheel configuration is selected to balance load distribution and ease of rolling over typical concrete shop floors. The larger rear wheels assist in overcoming minor floor irregularities, while the front casters provide steering capability. The undercarriage has a footprint of 25 inches in width, 45 inches in depth, and a height of 5.25 inches, adding minimal elevation to the machine while providing maximum stability. With a net weight of 67 lbs, the K841 is a substantial accessory built to match the durability of the Idealarc series it supports.
