<p>The device is intended for the thermal spraying of deposit-welding materials and consists of a jet focusing nozzle with, arranged therein at the feed side, an axially adjustable burner nozzle (5) or nozzle holder (6) with nozzle (5) and with devices for the regulatable feed of operating components. In a device of this kind, in order to be able to dispense with a relatively complicated electrical ignition operation and effect the ignition without risk of explosion in a conventional and simple manner, the device is designed such that the focusing nozzle (7) is split, in the region of its feed-side end (1'), transversely to the nozzle longitudinal axis (8) and such that the nozzle front part (9) with its jet focusing channel (3) is arranged so as to be adjustable with respect to the other part (10) arranged on the nozzle (4) or on the nozzle holder (6), with release of the nozzle (5). <IMAGE></p> |
