I just found out that nitrogen won't MIG worth a darn.
I went the other day and traded out a bottle of mixed gas. Didn't look at the new bottle, as both me and the guy doing the exchange spoke fluent English. I DID take off the cap and make sure the valve was tight, a problem I had encountered before.
Fast forward today. I get all ready to weld, and the first weld looks crappy. I check the connections and make sure the gas is on. I do another bead. Still funky. I look, and I am welding with Nitrogen.
I turned it up and glopped and bubblegummed some more on there, just a lockbox. My friend said just to put it on, and he'd do some touchup with Bondo and paint.
Sad world. I don't care if it's the Wendy's drive thru window, or the welding store. Ya gotta check your stuff before you leave. What happened to people who know how to make change and fill an order?
Rant off.
