I wouldn’t be afraid of a 12 wheel. 14 and 16 look like they’d be ok if used prudently. I wouldn’t touch the 18-20 wheel WRX.

Sounds like if I can get one of these at a really good price I could rebuilt it and make some $$$ on it.

That pic set showed what I was taught to call cold fusion.
That's a weld that is hot enough to roll out but not hot enough to fuse into the metal of either the pad nor the tube.
Easy fix at the factory - - - up the volts on the wire feed welding rig by at least 2 or maybe even more.
Likely automatic welds or the welder really doesn't know what they're doing - - - - quality first pretty second!

If you have a machine like this you need a carbon arc gouging setup (means you will need an air compressor that will give 90 psi and likely at least 20 cfm if not more!)
Welder needs to be able to hold at least 300 amps for a decent sized gouging rod (I'd guess a 3/8" rod would work and you could get other options to work but might be a bit more interesting).
Burn out every last weld (one at a time please!!!) hit them lightly with a grinder to clean them up nice and then weld 'em back up.
Cold fusion is not hard to achieve with hard wire.
I really like running a tri-gas and then sitting at 27 or even 28 volts on the feeder (tri-gas gets me spray transfer quality a volt or two lower than with a single or dual gas system) for hard wire.
Another option that can enable you to pile the pounds of weld in a day is to use powder cored wire (0.052 or 0.062 if your weldments are at least 1/4" think and you can and will move fast of 3/8" thick for most guys (you can easily get burn through!!!)).
Powder core doesn't like either vertical up or overhead but it is a serious winner on higher performance materials in flat or horizontal work.
