s Les chalumeaux utilisent deux gaz, l'un denomme carburant et l'autre appele comburant. Certains chalumeaux utilisent l'air comme comburant, mais ils presentent ['inconvenient de ne pas avoir une temperature de flamme tres elevee. D'autres chalumeaux utilisent un comburant pur tel que l'oxygene par exemple, ce qui leur assure une temperature de flamme o beaucoup plus elevee et un prix de revient tres important, du fait des bouteilles qu'il est necessaire d'acheter et de recharger. La nature des gaz utilises determine communement la temperature de flamme. I1 existe aussi a l'etat de prototype complexe de laboratoire une technologie de prechauffage des gaz dans un chalumeau permettant d'augmenter la temperature de flamme, ce prechauffage etant assure par un autre bruleur a  s Torches use two gases, one called fuel and the other called oxidizer. Some torches use air as an oxidizer, but they have the disadvantage of not having a very high flame temperature. Other torches use a pure oxidizer such as oxygen for example, which gives them a much higher flame temperature and a very high cost price, because of the bottles which it is necessary to buy and recharge. The nature of the gases used commonly determines the flame temperature. There is also in the state of a complex laboratory prototype a technology for preheating gases in a torch making it possible to increase the flame temperature, this preheating being provided by another burner at

Le dispositif selon ['invention permet de realiser un chalumeau a air prechauffe sur la base d'un decapeur thermique ce qui permet d'augmenter o sensiblement la temperature de flamme sans pour autant utiliser des gaz  The device according to the invention makes it possible to produce a preheated air torch on the basis of a heat gun which allows the flame temperature to be increased or substantially without using gases.

Ce dispositif hybride garde alors une fonction de decapeur thermique electrique et il est aussi un chalumeau a air prechauffe lorsque l'on decide  Observations can then be made, it emerged that the flame temperature is then increased by several hundred degrees.

Un decapeur thermique est generalement compose de deux principaux organes, une petite turbine propulsant l' air au travers une resistance de chauffage. La resistance de chauffage est de puissance fixe, la turbine delivrant toujours le meme debit alors, la temperature de sortie de cet air reste constante. L'adjonction de buse permettant d' obtenir des flammes tres concentrees pause un inconvenient majour. En effet les pertes de o charges sur ce genre de buse vent tel que le debit d'air est considerablement diminue, la temperature depasse alors les limites maximales admissible par les composants entranant des deteriorations fatales. Cet difficulte  A heat gun is generally composed of two main parts, a small turbine propelling the air through a heating resistor. The heating resistance is of fixed power, the turbine always delivering the same flow rate then, the temperature of exit of this air remains constant. The addition of a nozzle to obtain very concentrated flames breaks a drawback. Indeed the losses of o loads on this kind of wind nozzle such that the air flow is considerably reduced, the temperature then exceeds the maximum limits admissible by the components causing fatal deterioration. This difficulty
