在高空中气割,采用老式割枪,双臂操作,极不安全。为此我们对旧式割枪进行了改制,做成单臂操作式割枪。这样在高空作业时,一手握紧割枪进行操作,另一只手握住扶手、栏杆等物,既方便又安全。改造办法:取旧式小号割枪一支,手柄打开,倒煨45°。枪头部分氧气管打开,整个枪头煨直,然后跑银焊焊死。改制后的形状见图1。嘴头部分也可以按图2改进,这样可以减 Cutting at high altitude, the use of the old torch, arms, extremely insecure. To this end, we reorganized the old torch and made it a one-armed torch. This work at high altitude, the one hand clenched the gun to operate the other hand holding the handrails, railings and other objects, both convenient and safe.
