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
