I'm designing a cart for a Miller DialArc HF plus Miller TIG cooler unit.
I just wanted to hear if you guys would use 4 swivel casters or 2 swivel
and 2 fixed, and why.

For any cart that just moves a few feet in the shop (ie table saw base)
I use 4 swivels so I can move it to exactly where I want it. Any cart
that has to go a fair distance gets swivel casters under the handle and
fixed casters on the other end. Much easier to steer it.
For shop use and moderately heavy equipment I use 3" steel casters. If
it has to travel long halls or outside over sidewalks I use 5" hard
rubber casters. If the surfaces are really rough, you need the small
pneumatic ones.

Ditto, with the proviso that the heavier it is, the shorter the 'fair'
distance becomes. A wire rack that I can fully control with my two index
fingers can have four swivel casters and go a mile without undue
fatigue. Some 500 lb monster that needs to go across the shop may demand
two fixed casters.
Clearly you should have two swivel casters and two casters that can
swivel or get locked in place. You'll have to custom build them, but
you'll be doing the work, so it's OK with me...

My buzz-box that I bought used came with a cart, two fixed
and two swivel. Better than no wheels, but someday when I'm
at Harbor Freight and they have 5 inch swivel castors on
sale (and in stock) the two fixed will be replaced.
Another thing to consider is whether or not the rubber
wheels will be exposed to hot metal/slag. Steel wheels
wouldn't care and nor do they develop flat spots from
sitting awhile in one position. I have to prop up my oxy/acy
cart or the wheels get flat spots...

It depends. 4 swivels are less stable to tipping moments, but make the
cart much more easily positioned.. 2 fixed; much more stable, but
often means you need to maneuver the cart due to the restriction of
movement 2 fixed wheels cause. Take your pick.
