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.

Grant

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.

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.

That depends on the wheel spacing VS the size of the load. Where is
the center of gravity?

If you have to move it more than a few (2-3) feet, 2 fixed and 2

You got that right. i made ONE cart with four swivels. never again.

In general, you will have an easier time moving the welder if you use only
two swivel casters--with four the thing doesn't always want to go in the
direction you are pushing. However, if you need to rotate it in place. four
swivels are much easier to deal with. Has anyone heard of casters with
swivel locks?

Yes, and they're great, just not cheap. I've used them extensively on
lab rigs. As all posters have pointed out, 4 swivel casters don't
travel well. However, they're great for nudging a cart into position
to make connections. The swivel locks work well.

I'm a 4 swivel man myself... makes it a bitch though, ya gotta find 2
shopping carts to raid, not one...lol..

FWIW all three of my locomotive stands (and a 4th I built for a friend) have
4 swivel, and they are 2 feet wide and 6 feet long, just makes it eayser to
move in the shop.

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...

You can live with both, but four swiveling casters is harder to
control, especially if you have some slope.

I agree with you, except that I haven't had the opportunity to dance thusly.
I think if one does put four swivels, that they should put them farther
apart than a 2-2 setup for tipping stability.

I also suggest that one gets those kind of casters with the brake so that
the cart will stay put when you want it to, or on uneven ground.

For me, I'd use four swivels with brakes, and positioned far apart enough to
make it stable. Even if I had to drop the frame a little (like a dropped
front axle on a hot rod) so as to reduce center of gravity and put the
wheels farther outboard.

Hmm ... and why not make an extension wing on two of the casters
and a matching wing on the leg, so you can drop a pin or a bolt in there
when you want to roll it some distance, and pull them when you need to
maneuver in tight places.

Enjoy,

I bought the stock Harbor Freight MIG cart (rather than re-engineer
"the cart" from scratch) and threw out the rear rigid casters. Put
two 8" pneumatic fixed axle tires mounted OUTBOARD of the cart tray
(not under it) at the rear upright of the welder cart, forward of the
bottle tray extension. (With the shielding gas bottles aft of the
axle.) The two swivel casters are at the front with the handle.

For a Dialarc and a water cooler (two heavy boxes) you might want to
play with the axle balance before fastening it down - Do what I did,
and put the rear axle on a slider of two sections of angle. Once you
get the balance right, drill four holes and bolt the axle slider to
the base of the cart - and if loads change, you can relocate the axle.

The axle crossbar is two rod nuts welded to a chunk of 1" C Channel.
The wheels are held on with large hex bolts sized to bottom the
threads leaving the wheel bearings running on the bolt shank, and a
few flat washers to take up any slack. If you ever get replacement
wheels with wider hubs, you just get longer bolts.

The pneumatic tires take the brunt of the load and are wide enough
to avoid tipping, and the swivel casters are along for the ride. The
fixed tires make steering slightly awkward, but it stays vertical.

If you go all swivel casters and they all swivel to the inside, you
better holler "Timber!!", if it's not perfectly balanced it's coming
down. And small rigid casters mounted under the table aren't a lot
better - you need a wide wheelbase with a heavy and tippy load.

Oh, and two 1/8" x 3/4" strap diagonal braces from the top shelf
down to the rear of the bottle tray, just in case - plus it gives you
a place to tie the bottles into the cart.

If you have to go over grass or dirt, you have the axle balanced so
you can pick up the swivels and run it as a two-wheel hand truck mode
to get through the rough patch.

Two 20-lb steel CO2 cylinders aft of the axle pretty much balances a
Miller Challenger by itself, and the stored 'stuff' on the bottom
shelf that adds caster weight can be removed for rough surfaces.

There's a trick to it. The baggage carts in european airports have
four swivel casters. Those crashing noises are from people who
haven't yet learned how to "drive" them. Once the knack is accquired,
they're actually easier than 2 fixed + 2 swivels.

4 swivels will let you get it into tight areas easier than the
other configuration. Whether that's a problem for you, only you can
answer. (I went with that in order to get a rolling cabinet to make
the turn into the storage space. It is a real pain to get moving.)
On the other hand, four swivels are like a hog on ice, You push
on the end and it sort of goes where you aimed it. Or not. Sideways,
then travel cattywampus. And pivot and spin while it does so. Very
annoying at most times.

This I learned too. The first set were over loaded. The second
set "function". If I were not moving everything out in a month, I'd
bite the bullet and get bigger ones. Might have to trim the top off
the "cabinet" (A shipping crate set on end.) to get it in the door if

The cart I made for my Lincoln 125+ has four swivel casters. The two
in the back are fixed now because of poor design on my part. The gas
bottle support interferes with the casters swivelling. I will be
changing the bottle mount in order to regain 4 swivelling casters.
Only two swivels make for a poorly manuvering weld cart.

Gad, I'd forgotten about that.

The apartment building I lived in had carts available to move
stuff in and out. Really helpful, save that the sidewalk was a little
bit canted, and the parking lot was not level, or flat. I wound up
getting myself my own hand truck to move furniture in (and later,
out).

Wise words about the tipping potential...

Earlier I picked up a heavy cart with all four wheels swivel...and who
ever build the cart place the wheels far inside the perimeter of the
cart. I recently had about 400 pounds of drill presses on the cart
when it decided to tip...excitement and curse words galore as it went
over in slow motion with me serving as the counterweight.

Other than a few bent brackets, crushed condensers and scratched paint
everything and everyone was all right.

The cart is on the top of the to do list to be redesigned for safety
and two RIGID casters.

FWIW...I had been in such a hurry that I forgot to check the placement
of the casters before using the cart....an example of how one's
stupidity can get you hurt.

Somewhere I saw swivel casters with a lock pin so you could convert to fixed. I'd
consider that option.

Its probably as old as I am, and it keeps working just hunky. Ive got
chasers for damned near every rod and pipe thread possible.

I wonder if new chasers are still available. I was able to purchase a new cutting oil
pump a year ago.

It seems to me that 4 swivels work for relatively light machines on a
flat floor, and tight places. Two and two are better for heavier
machines, rough floors or dirt, and longer distances.
