using a 140 Hobart, 75/25, .024 wire- what would be a good starting setting for 1/8"-3/16" thick hrs?
I have it set to 5, and wire speed is at 70ish, gasflow is at 25. pretty sure I'm on a 30 amp circuit, and I bevel and pre heat everything that thick with a torch, then multi pass it. looks ok, passes hammer test but I've been reading around on here and i'll cut some stuff apart and etch it today or tomorrow.

just curious if the settings sound like they're in the ballpark. yes I did search first

YUP. Even so it's still a 1/8" machine....a very decent one.
Quit trying to make a 110 MIG something it aint....... and can never be.No that chittee flucked corp wont help either.
Use it for what it's awesome at. 1/8 and less and preferably on pure co2/030.
C25/023 is for a body man. It fits very well there

Under real world conditions the machine really is an 1/8" max machine. Sure you can go to all sorts of extended lengths to try and get that extra 1/16" of an inch, but you'd still get better consistent results simply using a larger machine at higher output. I simply wouldn't trust that you'd get consistent good welds with the limited duty cycle you'd have maxed out on output along with all the other variables that would have to be taken into consideration.

I don't wana get into the whole 110 vs 220 thing, I mostly got it for bodywork, art, hobby fun type stuff 1/8" or smaller. Not building bridges over here haha-but I did have just a few joints to do that were 3/16". I got some Lincoln(211 I think) 030 wire last night and after fiddling with the wire speed it's working better than the 023, much hotter. Thanks!

Don't expect a ton of penetration but it should work for some stuff. I wouldn't use it on anything structural. But if you want the most penetration out of a small 110v welder you need some .035 flux
