| mig gas - CO2 vs CO2/Argon mix Anyone used both and have feedback from using both? When I was working in a shop we only ran straight CO2, and for home use I had a couple soda cylinders with plain CO2 as well.
I've read the Argon mix lays flatter beads with a better appearance and less splatter, though CO2 has better penetration.
Being a cheapskate, my inclination is to keep using straight CO2, but if I fab stuff to sell, might look more blingy with the mix.
Feedback from experience welders that have used both? |

| I have used both and will definetely only use mix only now for the most part. CO2 does spatter more and I an not convinced there is any better penetration. What is the welder you are used? |

| x3 for me on mix gas. We'd been using mix in my weld lab and the school switched to straight CO2 for a "cost savings". Had to spend more time cleaning welds after that. You can even hear a difference, Co2 pops like bacon cooking, the mix sounds more even. |

| Mix here too. Used co2, burns the crap out of ya when welding in upsidedown positions. Got the scars to prove it.(that statement makes me sound like kind of a 'tard)........

75/25 for hard wire.

| ? The point of the flux core is for the flux to shield the puddle from the atmosphere so you don't have to use gas. Unless I'm misunderstanding what you mean by dual shield wire?? |

| you're thinking of inner shield wire, also called flux core. it requires no gas....like stick welding from a roll, instead of a rod.
we use outer/dual shield in both black and stainless varieties, but with straight co2. it's known as flux core too.

| We got talked into trying Blueshield 23 ( CO2, AR, O2) a couple of years ago and got hooked on it. Any advantage is good for amateurs like me.
BLUESHIELD 23
Allowable Impurities or Components:
BLUESHIELD 23 is a blend of argon with controlled additions of carbon dioxide and oxygen.
Applications:
-GMAW (MIG) welding of carbon steels in all transfer modes, short circuit, globular, spray and pulsed spray transfer.
-Excellent for robotic applications
-MCAW (metal core) welding of carbon steels.
Benefits:
-Reduced burn-through on very thin gauge material when welding in the short circuit mode.
-Smooth stable spray arc with low spatter and excellent bead appearance. http://www6.us.airliquide.com/cgi-bi...rodCategory=CG |
