Thanks to everyone who contribulted. I have learned a lot. For the curious,
my problem was that the fuel valve on the Little Torch had become so loose it
had no seal. I tightened it and it’s working perfectly.
I took the advice on pressure settings…tip size and pressure size being
the same. Also went to a larger tip (from a 4 to a 5). Soldering today was
a joy!!! I feel like I have jumped over a hugh hurdle.
I am one happy camper…er, jeweler!
