New PP256 testing

[zoama]

most AR/CO2 mixes are used with the mig process, let that be solid wire or flux wire.

The only AR/C02 mix I've seen in one bottle is 75/25 and no gas is used with flux core wire... We don't want to confuse anyone new to welding.

There are many Ar/CO2 mixes. I never touch the 75/25 myself. C18 is my poison.

Do you have a link to more info on C18 ? I'm not having much luck searching.

Its 82/18 Ar/ CO2.
Its an AirGas proprietary blend.

Most flux core wire doesn't require gas. I have read about a type of flux core wire that is a dual-shielded wire. It has a flux core but still requires the use of gas.

Dual shield offers the best of both worlds.

You can use AR/CO2 with flux core. Many shops around here flux MIG with gas. When I go to the local ironworks for my steel, that is all they use.

I know this is a TIG thread and all, but.

On the MIG MIX, I use C25 for MIG, might try C18 one trip (Mark really likes it).

I've lately been using Stargon (PraxAir thing I think, yes I am finally doing business with them again). I will use it more, as for some reason that tank never seems to drop much compared to the AR/C25. I seem to need less of it to get the job done. It is a AR/C02/O mix (says something like N.O.S on the tanks).

On the DOT, I swap 250s all the time, flat in the back of the truck. No issues there, BUT if you do not have a cap on the top, I was told it was a $5000 fine.

Thanks for the lessons guys. Non professionals don't get much exposure to these things.

To paraphrase what the 40 year veteran welding instructor told me in college about something similar "Once you try it, you'll throw rocks at the 75/25"

Tired of dull welds, BB's and spatter? yep, I would be too, if I used 75/25.
