If you want to understand how blow torches actually work, this video is a technical deep-dive into the combustion chemistry and physics of torch design — including the differences between butane, propane, Trade MAP / MAP-Pro, and the role of air vs oxygen as the oxidiser.
This is not just a product comparison.
It’s an explanation of what is actually going on in the flame:
how different fuel gases burn, why flame temperature changes, what oxygen really does, how torch design affects performance, and why some setups are dramatically better for heating, brazing, soldering or cutting.
In this video I cover:
- blow torch combustion chemistry
- how propane burns
- how butane burns
- how MAP-Pro / Trade MAP burns
- air-fuel vs oxy-fuel torch design
- flame temperature and heat transfer
- how oxidiser choice affects torch performance
- why oxygen changes everything
- how torch design affects efficiency and usable heat
- why hotter is not the whole story
If you’ve ever searched for:
- propane vs butane torch
- MAP-Pro vs propane
- oxy propane vs air propane
- how blow torches work
- torch flame temperature
- combustion chemistry of propane
- how oxygen affects flame temperature
- best gas for a blow torch
- torch design explained
- brazing torch science
…this report should help.
The aim here is to explain the underlying science clearly enough that you can make better decisions about torch selection, performance, safety and real-world use in the workshop.
