Re: Tig Welding for Gunsmithing
I love to talk about welding!
As eric mentioned, anything approaching "precision" is tig work. Farm equipment and bridges are mig/stick work. Tigs will all run a stick, so your only loss is the mig. Not a big loss unless your job requires lots and lots of filler metal, where the never-ending spool is convenient.
For a crowded shop, the Dynasty is perfect, as its compact and light. Syncrowaves are trusty old Trojans, but big and heavy.
Also, the dynasty makes so-so welders look like pros, particularly on Aluminum. The AC high frequency control is frickin awesome. Makes cleanliness much, much less important, and allows a much tighter weld puddle.
Having learned on a sync 250, the dynasty almost drives itself.
However, as I mentioned above, I'm a Miller man but I logged at least 1000 hours on a Lincoln precision tig 275 (I think), which would pump out 333 amps. That was more comparable to a syncrowave and not a dynasty, but really a very very good machine. Other than changing torches once or twice because other users were careless, it was exceptionally reliable and ran beautiful. In fact, Lincolns "micro start" high freq start is superior to Millers. It will ALWAYS zap a nice arc out. First time, every time.
