I have one of those cheap Mapp gas + nozzle torches I'm using for sweat sodering and the tip clogged up today. How do I go about cleaning it?
I have doubt it's even the tip clogging - could be a valve failure and have the described symptoms. I have never needed to clean the orifices on a propane torch, and I've been using them (the same ones, for the most part, other than having them walk off sometimes) for decades. Oxy-acetylene, yes - those can and do get sooted up. Propane/propylene-air - never.
Sometimes "cheap" is expensive, and "costly" is inexpensive.
