I use the “Little Torch” which does have a variety of tip sizes.
Several years ago, I dropped my torch and one of the tips that I use
a lot, got damaged. I needed to use it that same day, so I drilled
out the crushed tip and hard soldered in a half inch length of white
gold tubing with the same inside diameter hole. It’s been fine ever
since. The hardness of the white gold is a plus, this one hasn’t
gotten mashed up like the original tip. I’ve also cut back old tips
and soldered in larger tubes for a bigger flame. Hope this helps.
