ABSTRACT:
An economically improved self-igniting torch tip which provides for variable flame sizes through the selection and attachment of interchangeable burn tips and venturis. The torch tip also includes a conveniently located and durable built-in self-ignition system which is mounted in a heat resistant housing on the outside of the torch tip. The electrode and electrical connection for the electrode are disposed substantially outside of the burner tube so as to not interfere with the flow of combustible gases down through the tube.
