@DKTractors Here's a video to help users start the bernzomatic map oxygen torch quickly and easily. Basically get the map flame as large as you can while the end of it still touches the torch top. Put a mark on the oxygen dial and count the turns to open basically you are shooting for around 1.75 turns open. See my other video for more tips https://youtu.be/8LKY9CYOLwI @DKTractors
