Can I use a TIG welder to melt metal in small crucibles?
It sounds like it could work. One possible problem I can foresee is this:
The arc will generate heat at the top of the metal, and melting down into
the crucible will be sort of equivalent to "penetration." There is a
likelihood that before you get all the metal heated up and melted, you will
overheat the electrode and damage it.
