Mig welder suggestions

Hobart 140, love mine
also love my tig!!!!

im not a professional welder but i have done my fair share... most welders even the cheap ones will do atleast 3/16" steel if not 1/4" but the question is how much do u want to spend...
i would recommend that you invest in a welding unit that uses gas.. its much easier to see the weld pool than with a iinexpensive "gasless" welder which uses a flux cored wire. it also benefits from being able to switch the gas as to what your welding... diff metals take a diff gas...."gasless" welders generally only do mild steel...due to the wire... also gasless welders leave a lot of slag on the project and u will always have to clean the welds up after your done. I would recommend a gas welder with a good adjustment of power settings and feed settings... the lincon "power Mig 140C" model looks to be a winner in my book... little on the pricey side of things its capable of gas or gasless welding... my $.02
