Miller 042934 Running Gear & Cylinder Rack

The Miller 042934 running gear and cylinder rack is a transport and storage accessory built for Miller welding power sources. It fits the Millermatic 130, Maxstar 91, Maxstar 152 and Econotig models. The rack holds gas cylinders with diameters between 6 and 9 inches. It keeps the power source and gas supply together on a mobile frame for workshop repositioning.

Suits owners of listed Miller welders needing

This rack suits owners of the Millermatic 130, Maxstar 91, Maxstar 152 or Econotig who need to move the machine and cylinder as one unit. It does not fit welders outside that model list. Buyers with cylinders smaller than 6 inches or larger than 9 inches in diameter should look at something else. It is not a standalone cylinder cart for other brands or cylinder sizes.

Cylinder diameter range 6 to 9 inches

The single specification that decides fit is the cylinder diameter range of 6 to 9 inches. Only cylinders within this range are held securely by the rack clamps. Verify your cylinder diameter before purchase to ensure compatibility with the running gear.

Questions about this item

How often should the cylinder restraints on the 042934 rack be inspected for wear?

Inspect the chains or straps that secure the 6–9 inch cylinders before each welding job; replace any that show stretched links, fraying or damaged latches.

What component on the running gear is most likely to fail first when the cart is moved daily across a shop floor?

The swivel casters and their wheel bearings take the brunt of daily rolling; watch for flat spots on the wheels or play in the caster stems.

How much heat does the rack itself absorb when a Millermatic 130 or Maxstar 152 runs all day?

The steel frame stays near ambient temperature because it only carries the gas cylinder and the power source — it has no electrical or cooling components of its own.
