I'm taking the step up from flux core to solid core wire.
I just dropped off my tank at Air Liquide to be sent away to have a valve put in.
What is the best or favorite gas to run?
Straight CO2 as its cheap or a mixed gas (blueshield for Air Liquide)?

Yeah dude reccomended it as its more popular being cheaper and all..
the mixed gas allows you a better weld on metal that isin't as clean supposedly...

The mix works good is all I can say. a lot of the stuff I weld isn't perfect. I don't clean the mill scale or nitriding off my plamsa cut parts, and it works great. i only clean up if it has a high load, or is really dirty. |

There's 2 different mixes too isn't there? Something like 90/10 or 75/25.

I've used CO2 a few times, it splatters a lot (shower of sparks). I use Praxair, think it's called autoweld, works great.

I use Praxair, think it's called autoweld, works great. I use the same stuff. Pricey for a little personal bottle. |
