K842 - Lincoln Electric K842 Idealarc DC600 Dual Cylinder Undercarriage

Technical Overview of the Lincoln Electric K842 Undercarriage

The Lincoln Electric K842 Undercarriage is a specialized mobility solution engineered exclusively for the Idealarc DC600 series of industrial welding power sources. Designed to address the logistical challenges of moving heavy-duty welding equipment within a fabrication environment, this undercarriage integrates a robust structural platform with a high-capacity dual cylinder rack. The unit measures 24.75 inches in width, 51.5 inches in depth, and 5 inches in height, providing a low center of gravity that enhances stability when the power source is mounted.

Constructed from heavy-gauge steel, the K842 is built to support the substantial weight of the DC600 rectifier alongside two fully loaded industrial gas cylinders. The rear platform is specifically configured to accept two bottles, securing them with a dedicated upper support bracket and heavy-duty chains. This integration allows for the transport of shielding gas directly with the power source, eliminating the need for separate cylinder carts and reducing the risk of cylinder handling accidents during equipment relocation.

The mobility system utilizes a four-wheel configuration featuring polyolefin casters. The wheel set includes two smaller 5-inch front casters for steering precision and two larger 8-inch rear wheels to handle load distribution and overcome minor floor irregularities. Polyolefin material is selected for its resistance to chemicals, oils, and metal chips common in welding shops, as well as its ability to maintain shape under static loads without developing flat spots. The undercarriage includes a sturdy, attachable handle that provides the operator with ergonomic leverage for maneuvering the assembly. Installation is achieved via a comprehensive mounting kit that bolts the undercarriage directly to the chassis of the Idealarc DC600, ensuring a rigid and secure connection.
