Agree, 10 amps should be ok. I too looked it up, but also noticed the Lincoln doesn't have user adjustable post flow. It's programmed for 10 seconds at 10 amps then ramps up to 17 seconds at 200 amps. Welding steel with a peak of 175 amps and 3/32 tungsten I typically have my post flow set around six seconds, though you'd need a little more with a 1/8" tungsten and associated current, or when doing stainless or titanium.
It's not uncommon when doing tig to frequently start and stop when tacking or reorienting yourself. Beware the argon will be flowing a good amount more than needed.
