The neutral flame is the ideal flame for brazing and welding with the Oxygen Acetylene Torch. But, if the bronze rod is not flowing quite right, you may want to try a carbonizing flame.

Most of what i do is very small work. I would lose dexterity if I wore gloves. Best advice is "if it is hot, don't pick it up". In over forty years of working with the torch I have only had one bad burn. Your question: "What do you recommend to new O/A users?" Can you be more specific?
George, your videos great. Minimal talking, excellent demonstration. Some of your small points, you don’t explain the reasoning,ex: “sometimes a carburizing flame helps bronze flow better.” WHY??? Wider footprint of heat, more ‘wind” pressure? I like to know the “why”. Thanks
Ron, I have no idea how that works. A welder suggested it 40 years ago and I've used it ever since. I am self taught with a lot of help along the way. There is much of the technical explanations I don't know. Best place to get an answer is from a welding engineer. They may be able to help. There are differences with high humidity and low humidity. A cold welding table and a warm welding table. The point is to intuitively become aware that something has changed and make adjustments.
im trying to braze a small gas tank /it had some cracks in it.it cracks a bit in places after ive brazed it.it can be quiey annoying and i was wondering if im doing something wrong.the cracks always seem to appear after its been brazed..any advice?
Martin, I've never brazed or welded a gas tank. The best I can suggest is to take a look at this video on brazing thin material: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-h0vIvipWVuY.html
