Howdy all. I'm new to welding and looking at purchasing a MM180. I am trying to figure out what size cylinder in need to purchase for my shielding gas. I keep hearing about k, t, p(?) size cylinders and have no idea how large or small they are. Is there a chart or reference sheet out there that tells me how many cubic feet these cylinders will hold? Also, what size would be best suited for this machine? I will be welding mostly old farm equipment and small fabrication projects. Thank you for the help.
