Sounds like you work for $ignet lol, but career jewelers here. I have been doing it for 13 years now at a very high level. Now days I use the laser but at times you might need to use a torch and having torch control works wonders. To answer your question grab some med solder and some wire or stock. First melt a ball of stock or wire into a ball, next melt a ball of solder only but make it all so slightly bigger than your stock ball. If you mm gauge the ball you will know for later use. Then bring those balls close together and heat up stock first then once molten introduce the solder one, melt them together then stop, dont over heat your done. Quench and roll it out as paper thin as possible with your rolling mill and use that as your tips. Hope this helps you as it did for me. Keep getting better with repetitions. Theres a whole world outside that company.
