What kind of places sell shielding gas for welding? I am sure that welding supply places do but I live in the middle of nowhere and I don't think there is one within 40 miles of my house. I did get my first bottle at Tractor Supply but they have made me mad. I paid $220 for a number #2 size bottle plus money for the gas too. When empty I was supposed to be able to bring it back for exchange. Before buying it I asked if it is often a problem that they don't have a bottle ready to exchange and the person assured me that they can fill a bottle there so no big deal. So I go there today and of course they don't have my size bottle ready and they can't fill them there and if I am lucky maybe the truck will deliver some in a couple of days. I am not happy about this!!!!! Maybe I am wrong but $220 for the bottle alone seems crazy expensive to me. I went for it because I thought it would be convenient but it is not. Home Depot and Ace Hardware don't sell shielding gas. Do propane places sometimes sell it? And I am also grumpy about crazy delays in the arrival of my painting supplies. My DC is naked and waiting. Ugh!!!!!
