Good things when you get skilled at using them yes you can used argon shield so long as it's pure argon not co2 mix.
Its like gas welding in respect the torch creates a weld pool which you add a filler rod to fusing the two together but unlike welding steel it's harder to determine when you add the filler rod with ally as if it gets too hot it will just flow away.
You also have different torch electrodes for different materials and have to grind them to a point with a small flat on the end this will then melt into a ball looking like a ball bearing but if you touch the electrode on the material or rod then it will become contaminated and you will have to re-sharpen it.
The rest is just practice but l would find out if their is a corse you can go on localy.
Good luck ;D

Main thing to remember is DC tig welders will weld steel and AC will weld ali.
You can't use your mig gas for tig, you have to use pure argon.
It takes a lot of pratice to get it right but its not as hard as some say
