I read that some people have taken their mig welder and turned it into a tig by drilling out a mig tip. Then they drill and tap the side to install a set screw. The tip then will hold a tig electrode to use. Anyone ever done this? Does it work?
One is a constant voltage process, the other is a constant current
process - so although it may "work" it won't work "well"
Stick and tig use constant voltage, while wirefeed (gas shielded or
flux core) use constant current. A normal stick welder would be a
better match fot TIG than a wire-feed welder (and tig welders DO work
well for stick welding - HF start makes striking the arc childs play)

You have it backwards:

TIG = Constant Current
Stick = Constant Current
MIG = Constant Voltage

There are of course many multi process machines available that can run
in both CC and CV modes.
