setting up a welding workstation

[akdsmer]

That looks like they took the frame off of a BBQ. Make what you like, but when it comes to welding there is also bending, beating and pounding going on. That usually requires a sturdy bench. If space is an issue, how about making folding sides, that are held up with some good bracing.

The plasma cutting section is a good idea though, as is the tool holders in the second link I provided.
