CNC Miller 255 Welder Cart
Our main shop needed a new welder, I decided on the Miller 255 for its portability and the fact that it had MIG steel and MIG aluminum, with Pulse option. The Big seller on this welder was its small foot print, making it portable. Often we have to fork lift an entire welder 12-15 into the air to reach a position on a semi trailer that needs repair. Fork lifting an entire welder with tanks on it is not ideal, and the operator of the welder is very limited to what they can do.
With hose extensions this welder would allow us to fork lift the welder into position, leaving the tanks on the ground and full access to the welder where the operator is at.

Description
This is a downloadable package for all the files to build the shown welder cart for a Miller 255 Welder.
The download link expires after 24hrs from purchase.
About the Cart Design:
This cart is specifically designed for the Miller 255 welder. Its main design function is to allow you to position the welder at the height that works best for you.
The base design positions the welder 36inches from the ground. This is a great height for adjustments and viewing that doesn’t require bending over.
The cart design utilizes 5in caster wheels and 10inch dolly wheels so that it rolls very easily with 2 shielding gas tanks.
How the Welder Fits:
The miller 255 welder feet fit into holes cut into the top plate that naturally secure it into position. The cart does not need a handle for pushing or pulling, this can be done from the Miller 255 machine itself.
Materials Recommended:
The base design uses A36 3/16 Steel Plate. Aluminum can be substituted. Thinner or thicker materials will require redesign of the parts that require bending.

3d Files included in the package
The 3d files in this package can be opened in Fusion 360 and all the individual components can be changed as desired. They can also be opened in Blender/Other 3d Program for modeling as they are to real world scale.
What tooling/machines are needed to build this?
This cart can be built with common fabrication tools/machinery. Such as (given) your miller 255 welder. The pieces that require bending can be bent via brake press or vice and hammer. You can provide the dxf files to a CNC plasma/waterjet/fiber laser shop or cut them yourself if you have access. The tubing and solid rods can be cut by bandsaw, cold saw, grinder, hack saw, etc.
Below are finished build photos of the cart with a Miller 255 with Steel MIG welding attachment and Aluminum Spool Gun attachment with 2 shielding gas tanks.

Finished Build Photos
The cart is made to fit together like a puzzle, eliminating measuring and need for a straight edge.
I designed this cart so that the welder would self place its self and be contained on the car without attachment straps. The welder places into holes that match the feet on the welder, keeping it placed on the cart.
The welder can be lifted straight off without removing anything.
