Remember you will also need argon gas, and that using CK "gas saver" front end torch parts, will mean you use quite a lot less gas.
I plan to save and get the good stuff, right now I do my welding where I work ( I'm a machinist). Just hoping to set up a small, very small side business, I want to add a LeBlonde lathe and Sharp/Brigdeport mill
