That'll be argoshield thenWould you get away with Ar/Co2
Yeah, I've never known the definitive answer to which is the best mix of gas to use for stainless. Just know that pure argon is kind of usable but still questionable.Stainless and argon via mig is questionable.
Or pub co2 teed into the argon to mix your ownThat'll be argoshield then
Or pub co2 teed into the argon to mix your own
MIG welding gases, argon or argon/helium for aluminium
MAG welding gases, argon/2.5% CO2 for stainless steel and thin mild steel
Argon 20% CO2, Thick section mild steel, most suited to flux cored wire
Argon/2%O2/ varying amounts CO2, argoshield type mixtures for differing thickness' mild steel
Where is the bottle from and what size is it?
If you're paying rental, it might work out more economical to give it back with the gas if you don't see yourself using it in the next year or so...
If it's a deposit bottle you're unlikely to get all the deposit back anyway if you hang on to it for a while.
Got to weigh up the cost.
he has a near full argon and a bottle of pub gas is 15 quidthat would work out more expensive than buying argoshield...argon is more expensive than argoshield anyway, and you have to pay for your own co2 as well, plus all the plumbing
To be honest we tend not to recommend Ar/O2 for stainless any more, but as you say Al, 2% O2 is brilliant for thin mild steel if you are more concerned about the cosmetics than the mechanicalsand Argon + 1 or 2% Oxy for both stainless and mild / low alloy steel.......if its still available that is
