Practice.
Maybe Greg will chime in on the heat and thickness. Also your choice of tungsten. Type and size for metal thickness?

+1 on 100' of practice, it took me at least that and 150 cf of gas to get close to comfortable.
From my experience TIG has next to zero tolerance for contamination and if you touch the tungsten or it gets splattered don't even try to continue, stop and regrind the tungsten.
Use Miller's phone app weld settings for a handy baseline amperage reference.
