Here is my custom welder cart,

Step 1: What I Was Thinking Of...

What I was thinking of, was a cart, small enough to travel on the local mass transit buses, large enough to carry all the goodies needed to do a job, and low cost. Surprisingly enough, most of the materials were saved / salvaged / scavanged / scrounged from the side of the road. Anyway, after some head-scratching, I was able to come up with a sketch, with some workable measurements.

Step 2: The " Infamous Materials List "..........

What I used, gathered in no special order,

Steel angle stock ( salvaged bed frames )
Sheet metal panels ( salvaged from air conditioner units )
Handle ( salvaged from defunkt cart )

Hinges, hasps, wheels, axle, etc. ( purchased )

Ain't it amazing what you might find, tossed to the side of the road ?

Step 3: Some Construction Details

I started with building the frame, making sure the welds were solid.

The side, back, & bottom panels were tack welded on the inside of
the frame.

And the doors, the center bay doors cut overly wide for some overlap
to give room for the "latch" , mounted on bolted hinges.

When this project got started, I'll freely admit to not taking any photos,
simply because the thought never occured to me.........

Step 4: Finishing Touches & Parting Shots

I've added an outlet with a stout extension cord, just for the fun of it.

Swivel casters on the front, for easy moves during a project.

Mask & Paint : Any which way you want, this was painted using the
ever present rattle can, with the colors of my "buzzbox" welder, which
will call this project "home".

The welder, by the way, is next on the list for refurbish & upgrading.
