Like many of you Im sure, I am always looking for new tips and techniques on how to do my job better. So I have a question for you all. In my opinion the number one enemy of a txv,(not including possible debris getting by a filter/drier) is my torch. I have always been curious why they make us braze a part in that is sensitive to heat and has short stubs to braze too. I prefer flare but as you know this is not always practical.
So my question: How do you go about brazing in a txv and protecting it from damage?
Myself I use a liberal amount of a thermal absorbing paste and wrap it with a wet rag.
