I find talking the rhythm (dab, dab, dab) or using pulsing is a good way to learn rhythm as it basically shows you when to add the filler.
The dimes just come from the stop start of filler rod. you can also whip back over like you would with mig and will give you the basic dimes look. Just be careful not to over heat the stainless. You should just tack it together and then back purge it otherwise you will drag a lot of oxidation into the weld as it penetrates to the unshielded side. It will look like crusty gray frosting (sugaring) on the inside which will then effect the colour on the outside.
I started the same way as you 2 years ago. Wanted to do a stainless exhaust for my mustang. went out a bought a tig on "tick" and learnt how to do it. i'm not pro or good. But i know a lot of the reasons why you get bad welds. welded and couldn't get better, spend hours online to find im doing one thing wrong. weld again, get better but still have problems. Few more hours on the internet. so i try an pass on what info i have to save people the pain!
With how good your fabrication skills are you will master it in no time!
