Abstract (en)

[origin: US4433358A] A torch provided with an automatic igniting device by which the combustible gas mixture needed for cutting, welding or heating metals can be ignited easily, reliably and with proper timing by manipulating a valve which must invariably be opened for feeding the pressure fluid to be used and effectively utilizing the pressure energy of the fluid for ignition. The automatically ignitable torch has outstanding advantages in respect of construction, fabrication, cost and durability.
