Number 5.5,
Go here and look at the very last cart on this page.....the "Universal Cart & Cylinder Rack, Miller part number 042-934.

If you are interested in that cart, then go here to download the Owner's Manual and tech specs. The manual will be close to the bottom of the model list. It's under "UNIVERSAL LARGE CYLINDER CART 042934 ".

At the bottom of the owners manual is a list of 3 different power sources that fit the top shelf of that cart. If your welder fits "inside" those dimensions, then that cart will work for you. We have a Synchrowave 180 SD on ours. There are several hole patterns pre-drilled in the top shelf. If your welder is a Miller, and it should be, your machine may fit as well without drilling new holes.
If you give me dimensions of your plasma, I can see if it will sit on the bottom shelf by measuring ours at work.
The $99 weld carts are borderline sucky. This is a nice cart. The price is a little steep, I think we paid $330 for ours, but my only complaint was that the black powdercoat finish was a little thin. Other than that, we're happy with it.
Well, the front handle is aggrivating sometimes, but that's about it.
