Blast Tips are suited for heating applications where an intense focusless flame is desirable. Blast tips are used for heating work on continuous soft silver soldering machines as well as batch type soldering set-ups. Blast tips are built to burn without the use of any refractory tunnel and are either self-piloting or built to prevent the flame from blowing away under normal conditions of operation. They are used in groups to heat a wide area such as the bottom of a kettle or mounted down a length of pipe as in a core oven.
