TIG welding

[CamaroAJ]

this is just stuff laying around i'm welding on, i know i'm real bad with a TIG but i bought it to learn and thats what i'm doing, i was using the mixed gas because i had it for use with my MIG. everything i was told about from a welding supply was wrong then, i am taking notes on what your saying and so far i'm already progressing. is the cup size ok or would you recomend another size? as far as welding on the car i'm MIG welding everything, learned to do it about 5-6 years ago so i'm more that conifdent in that. Thanks for all your help Matt.
