For messing around and hobby stuff, look at a dual voltage stick welder. You can checkout the a Hobart MVP 160 or a ESAB Rogue 180i at Northern Tool and I they have a Lincoln inverter unit there too. Both of these will run a 1/8” rod and can be run off of a 120 or 240V circuit. For ranch stuff you can run 3/32 rods with a small generator pretty easily for most remote repairs and you have 240v capability to run larger rods with higher duty cycles in the shop. Get a few pounds each of 3/32 & 1/8 6011, 6013, 7014 and 7018. Go by a steel yard (Steel Supply is who we use in Houston) and get some 1/8, 1/4 and 3/8 drop of flat bar or sheet steel. Get your welder guy to show you some stuff and then practice running some beads like above and then move on to butt and fillet welds. Then find some shit that needs welded up and weld it. If you fuck up the weld, you can always grind it out and try again. Shits not hard, they teach it to 9th and 10 grade ag students. Or just buy an inverter Mig setup with an auto-set feature, some gas tanks and be running great beads in a couple of hours.
