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

Get Your Idealarc Moving

Let's face it: the Idealarc DC400 and DC500 are beasts of machines, but moving them around the shop shouldn't be a back-breaking ordeal. The Lincoln Electric K841 Undercarriage is the definitive answer to mobilizing your heavy industrial welder. Whether you are reorganizing your shop floor or need to bring the power source closer to a large fabrication project, this undercarriage gives you the freedom to roll your equipment exactly where you need it. No more dragging cables across the shop or struggling with makeshift carts that can't handle the weight.

Dual Cylinder Convenience
One of the biggest hassles in a busy shop is managing gas bottles. The K841 solves this by integrating a heavy-duty platform right onto the back of your welder that holds not one, but two gas cylinders. This is a game-changer for welders who run dual shield setups or need different gases for different processes (like switching between MIG and Flux-Cored). Everything you need—power source and gas—moves together as one unit. The included chains and heavy-duty supports mean your tanks stay upright and secure, even when you're on the move.

Built for the Grind
Industrial floors can be rough, but the K841 is ready for it. It rides on a set of tough polyolefin wheels—larger 8-inch wheels in the back and nimble 5-inch casters in the front. This setup makes pushing and steering your heavy welder surprisingly smooth. The kit also comes with a sturdy handle that attaches directly to the unit, giving you plenty of leverage to navigate tight corners or cluttered bays. Installation is straightforward with the included mounting kit, so you can get your machine mounted and rolling in no time. Upgrade your setup with the K841 and stop fighting with your equipment.
