OVERVIEW

Upgrade Your Mobile Welding Setup

Stop wasting time swapping out gas bottles every time you switch from MIG to TIG. The Miller Dual Cylinder Rack Conversion Kit (301454) is the ultimate upgrade for your Millermatic, Multimatic, or Diversion welder. If you are using the standard #301239 running gear, this kit transforms your single-tank cart into a professional dual-tank station. This is particularly valuable for fabricators who use multi-process machines like the Multimatic 215 or 220 AC/DC, where you need pure Argon for TIG and Aluminum MIG, but a C25 mix for steel MIG. With this rack, both bottles travel with the machine, ready for action at a moment's notice.

Built for Convenience and Stability

Miller designed this kit to be as rugged as the welders it supports. The heavy-duty steel brackets replace your existing rear rack, providing a secure "side-by-side" platform for two gas cylinders (up to 7 inches in diameter each). The kit reuses your existing heavy-duty rubber wheels, widening the stance slightly to maintain excellent stability even with the added weight of a second bottle. Security is paramount when moving high-pressure gas; that's why the kit includes robust safety chains for both cylinders, ensuring they stay upright and secure while you move around the shop or garage.

More Than Just a Rack

This conversion kit doesn't just hold tanks; it organizes your entire workflow. The newly designed top bracket features built-in tool holders that put your most-used accessories right at your fingertips. You can store your MIG pliers (welpers), chipping hammer, wire brush, and even tubes of TIG filler rod directly on the back of the cart. No more hunting for tools or balancing them precariously on top of the power source. Whether you are a DIY hobbyist, a motorsports fabricator, or a professional in a manufacturing environment, this conversion kit maximizes the efficiency of your Miller equipment.
