Abstract

A portable gas torch has a metal burner tube defining a gas flow passage through which gas is adapted to flow. An igniter in the gas flow passage generates a spark to ignite gas flowing through the passage. The torch has a wire holder for positioning the igniter wire in the gas flow passage and a flame holder downstream from the wire holder. The wire holder comprises a central hub having an axial bore and at least one spacer on the hub for contacting an inside wall of the burner tube to position the hub at a predetermined radial location in the gas flow passage. The axial bore is sized to enable the wire to be held at a selected location downstream from the hub. The wire holder comprises a dielectric material to allow a spark to jump to the inside wall of the burner tube.
