Can I mig weld with pure argon?

Pure argon gives very poor penetration on Steel MIG.

Just hook up the argon bottle, set flow to about 15- 20cfh..reverse the polarity of the leads and you are up and running.

I use pure CO2 for most mig welding on the old rough stuff I have kicking around..25/75 for fancy stuff and keep the argon for the tig, but Ive done argon mig. The welds tend to be shallower and more rounded..shrug

"Pax Americana is a philosophy. Hardly an empire. Making sure other people play nice and dont kill each other (and us) off in job lots is hardly empire building, particularly when you give them self determination under "play nice" rules.

Think of it as having your older brother knock the s*it out of you for torturing the cat." Gunner

Rod: Straight Argon will give you less penetration and under cutting. CO2 would be better for use with solid wire than Argon. However, I'd stay with the self shielding fluxcore if money is _the_ issue.
