Why does my torch go out when tipped upside down?
Some of our torches (MT525C, MT245C, and MT200C) are designed for plumbing or soldering – uses that work best with the torch head upright. For this reason, they do not have a pressure regulator to control the flow of fuel through the torch. When these torches are inverted, the liquid propane works its way through the torch and extinguishes the flame.
For work that requires inversion, we recommend a pressure-regulated torch, such as the MT535C, MT551C, MT555, MT560C, MT565C, or MT579C.
