It's a shielding gas to keep oxydising elements away from the weld.
I've gone for an Albee exchangeable 11 litre cylinder/regulator from Air Liquide, Philip has just gone down to Bedford to collect it.
£156.45 + VAT for the initial purchase and gas, refill £52.57 plus VAT.
There is a 13 litre cylinder too, but we'll try this one first and see how we get on.

Its how the arc behaves therefore stability and temperature hence you use pure argon when mig welding aluminium and tig welding anything exept for odd stuff that likes mixtures of helium.
When mig welding heavy steel mixtures with more argon are used for heat.
No actual chemical reaction doesnt mean its not active, it does more than a simple barrier gas by improving arc conditions

Our 'new' TIG welder arrived this morning, we've got it running OK, just playing with bits od 16g sheet steek to get the hang of it.
Interesting technique needed and it isn't as easy to pick up as you'd think, but I find it easier than Philip who hasn't done gas welding.

straight or reverse polarity
you tig on reverse polarity
oerlikon are good things, i had a oerlikon mig and it punched well above its weight and their welding rods are beautiful to use
i run a miller syncrowave ac dc tig which im trying not to sell at present!

I couldn't be bothered with all the messing, I've had an account with Air Products for years and just rent a half size bottle, it even come's with a built in regulator so no need to worry about that either. From memory it's about 85% Argon, 15% CO2, no issues, just plug in and use, lasts ages and is what it was designed for. Bottle rental is about £80 a year but they have many rental options besides this.
