Les chalumeaux utilisent deux gaz, l'un denomme carburant et l'autre s appele comburant. Certains chalumeaux utilisent l'air comme comburant, mais ils presentent l' 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 beaucoup plus elevee et un prix de revient tres important, du fait des o bouteilles qu'il est necessaire d'acheter et de recharger. La nature des gaz  The 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, owing to the bottles which it is necessary to purchase and recharge. The nature of the gases
