Buying a Tig Welder & Taking a Class**

Not trying to be critical, considering the amount of time you've been TIG welding you're doing great!

Just trying to help out. TIG welding is definitely NOT fast like MIG welding can be, the biggest limitation is really how fast you can advance your fill rod. With MIG welding you can just turn up the wire feed, but with TIG your going to run into how fast you can really advance the rod by hand. Once you've hit that limit, you just have to slow down the puddle movement to match your fill speed. Usually you can reduce the heat a little, since you'll get more heat into the metal as you slow down. And as you've discovered, the bigger the gap you have to bridge the slower you're going to have to go, because you'll need to add a ton of fill rod. TIG welding is pretty precise, you need to have tighter gaps and a much cleaner surface to get things to look right.
