Igniting a MAPP Torch to Sweat Copper Pipes

Video Transcript

"Hey again Don Golden for Expert Village and we are working on copper piping. One of he essential ingredients is fire. Fire baby, got it right here in the can. This is the mat gas that we all know and love. It is like propane only a little bit hotter. Here's what you have got to do. You have a valve on top that opens and closes and obviously it is closed now obviously you would hear this, a hissing noise. That is what you want to hear the gas is coming out. The other thing you want to look at is your nozzle adjustment. This controls your flow rate of oxygen or just simple air that goes through it and depending on the kind of flame you want it will get hotter or a little cooler. I pretty much have it set at the bottom because I want it as hot as it can be. Now let me show you how to light it safely. You want to open it just until you hear a little bit of gas coming out. Now there you go. Now you are going to adjust this to the length of the flame slightly but right there you want a nice blue flame, you don't want to see a lot of yellow. Blue is very hot and we can turn this up if you need to. Now when you operate this thing, remember, it's going to be very hot so don't touch this after you have turned it off, be careful, I've burned myself more than once. Okay, there you go."
