Advice please , a MIG welder cart

Readership,
I am about to fab a cart for my(new) Hobart 140 MIG w/CO2 bottle ,
and need some advice as to 'wheel' choice .
I'm not really happy with the 4_wheel, castered carts that
the mfgr offers ... druther have something that moves easier
over soil/dirt.
I'm planning on putting the tank behind the MIG ( in line ) ,
and am trying to keep about 60% of the weight ahead of the axle
when the cart is "flat"( at rest ) on the ground.
And, some kinda 'tool' shelf atop the MIG case that doesnt interfer
with opening the MIG lift_up, wire feed access, door.
The cart will operate over hard_packed soil/dirt , some driveway asphalt
...
and will be a two(2) wheel tip_up cart similar to a hand dolly.
My question is ...
for this kind of "soil/dirt" mobility , which wheel type is better ...
. an inexpensive, lo_speed 10"(wide) dia pneumatic
. an inexpensive, lo_speed 20"(narrow) dia pneumatic ( similar to a bike
tire ).
I've heard that larger, 20" wheels operate better over dirt than 10"
wheels ,
but no experience 'here'.
Added,
it plugs direct into a GFI outlet. :-)
=Any= comment welcome .
Thanks for all replys,
Ed

I agree those hard wheels shake up the MIG,
I have (rather my dad and i have) one of these:

I replaced the hard plastic wheels with some bigger/wider soft ones (about 10" dia X 4" wide foam tyred off an old hover mover add on frame) and now it rolls nice and smooth.
For stability I would suggest having more than 60% of the weight ahead of the axle.

Whoosh, my tank is only 28" tall
'Point' taken ... will try for a frame 'adjust', fwd & bk. Maybe adjust the axle fwd & bk. Easier of the two.
Thanks, Ed

It didn't come with that tank! ours is about the same size as yours :-) Actually we are using a CO2 tank from the social club bar next door to my dads. We did buy a tank with the welder but I forgot to turn it off one day and it leaked enough to empty over a couple of days :-( Doh!

Had the same problem. Everything rattled around and lost tools, bolts came loose. Went to HF spent $17.00 and replaced front with 4" rubber casters and rear with 10" pneumatic tires. Ace hardware for 1/2" rod for axles and 1/2 to 5/8 shims. Used tool chest liner under tank and on lower shelf. They can't hear me coming now. Going to put pneumatic swivels on front and have a true all terrain welding cart. This now goes pretty good over short grass, packed sand and dirt. A lot of difference. See pix @

I have a friend who also uses about 10" pneumatic tires on an O/A cart with some fairly large bottles. I believe his may have come off a lawn mower. They're pretty wide - ? 5". Anyway, he pushes that all around on packed dirt and some that is not so well packed.

The larger the diameter the better it'll roll over bumps. But to narrow and it'll sink into the ground. Best is large diameter and wide.
If the dirt is for sure really hard packed then the narrow tires will work. But any softness will bog it down.

Wide tires, and spaced the farthest apart you can get them is the best idea, I think. I don't think big diameter is as important as having them spread out, especially if you use a tall bottle. It gives a bigger more stable base. I use one of those garden cart things that have the inflatable fat tires, and it works pretty good. It was quick to adapt, and cost about as much as I would have spent on materials. YMMV, and probably will.

Without going and looking at a wheelbarrow, 10" and wide sounds like a wheelbarrow type tire, which does pretty well on dirt. However, it is true that larger diameter is less put off by bumps and holes than small diameter. I'd start by seeing if you can find 20-27 inch "free" somewhat fat (mountain bike) wheels and tries by checking at the local landfill/ transfer station/recycling center. Or buy a yard sale bike or two if you can't find any for free.
If you're looking at soft dirt, wide matters more. If the dirt is reasonably hard, large diameter matters more. You say it's hard-packed dirt, so go with large diameter.

Chaz. That is what I am going to do also, but I am going to have a shelf right under the welder for supplies ( hammer, pliers. ect.) Don D.
