    • PURPOSE: A plastic welding torch is provided to perform plastic welding operation without using electric power while installing the plastic welding torch to a gas welding torch. CONSTITUTION: Valve installed at upper portions of a burning gas tank and an oxygen tank are opened for supplying gas and oxygen to a gas welding torch(20) through a gas pipe(14) and an oxygen pipe(13). A third adjusting valve(42) is opened for flowing gas to a mixer(32). In a closed state of the first adjusting valve, a second adjusting valve(44) is opened for mixing the gas and the oxygen in the mixer. Then, the mixed gas is discharged to a front end portion of the gas welding torch through a third pipe(23). Herein, an ignition switch(36) is pushed for generating spark. By slowly opening the second adjusting valve, the oxygen from the oxygen tank is transferred to an oxygen spraying torch(50). The oxygen is heated by welding flame for being discharged through a rear end portion of the oxygen spraying torch. By examining color of a temperature measuring metal(52), temperature of oxygen is decided. In case of a proper temperature for welding plastic, welding operation of plastic is performed.
    • 目的:提供塑料焊枪,在塑料焊枪安装到气焊枪的同时不使用电力进行塑料焊接操作。 构成:安装在燃烧气罐和氧气罐的上部的阀门被打开,用于通过气体管道(14)和氧气管道(13)向气体焊枪(20)供应气体和氧气。 打开第三调节阀(42)以将气体流动到混合器(32)。 在第一调节阀的关闭状态下,打开第二调节阀(44)以混合混合器中的气体和氧气。 然后,混合气体通过第三管道(23)排出到气体焊枪的前端部。 这里,点火开关(36)被推动以产生火花。 通过缓慢打开第二调节阀,将来自氧气罐的氧气转移到氧气喷射炬(50)。 氧气通过焊接火焰加热,以通过氧气喷枪的后端部分排出。 通过检查温度测量金属(52)的颜色,确定氧气的温度。 在塑料焊接温度适当的情况下,执行塑料的焊接操作。
