The main differnce I see is that most carbide tipping is still done by hand, but Stellite is almost universally put on by an automatic machine. When brazing by hand, you do the annealing right there and you get a "feel" for how long to hold the torch on the tip. Annealing with a machine, or even a separate gas annealer is a little more finicky because the performance depends so much on how it is set up. Also, people assume that the settings never need changing, but power cables degrade, torch tips get clogged..... Automatic annealers work, but they need to be watched.
