A torch assembly comprises a rigid elongated burner tube having a distal end with a bend terminating in a fuel discharge nozzle tip directed backwardly toward the elongated burner tube in a J-shape configuration forming an acute angle relative to the longitudinal axis of the elongated burner tube. The nozzle tip is configured to be positioned in hard to reach places for treatment of a part by the ignited fuel. The elongated burner tube rotates 360 degrees about its longitudinal axis. An ignition device may be mounted on the elongated burner tube for igniting the fuel. Alternately, the elongated burner tube may be comprised of a flexible stay put metallic tubing which can be formed into various configurations and which remains in this configuration until it is formed into a different configuration.
