| 摘要 |
The invention relates to a welding, cutting and soldering installation allowing the use of cylinder fuel gases, such as butane, acetylene or other gases which, together with the cylinder oxygen, generate, by means of a usual welding or cutting torch, a flame which can develope the temperature required for welding, cutting or soldering various metals or metal alloys, respectively. The fuel gas and the oxygen may also be packaged in cylinders (8 and 9) of relatively reduced capacity, also adequate to portable installations.
