A cutting torch arrangement comprising
- a plurality of longitudinally extending thermal bars each comprising a burner pipe having combustible rod-like elements extending along a length thereof, with longitudinal gas passageways formed therebetween for feeding of oxygen gas along the interior of said pipe and enabling igniting and burning of one end of said thermal pipe,
- and composite support means compositely supporting said thermal bars at one end thereof remote from the opposite end thereof and having gas flow passageway means formed therein connecting with the interior of each of said thermal bars,
- said composite support means comprising a common securing, supporting and gas feed manifold having a common gas feed opening therein and multiple thermal bar-supporting and gas feeding openings for secured supporting engagement with corresponding respective ones of a plurality of thermal bars,
- and a common gas manifold chamber formed within said securing, supporting and gas feed manifold and connecting in gas flow connecting relation between said common gas feed opening and said multiple thermal bar-supporting and gas feeding openings is said manifold.
