等压式焊割炬在国外已被广泛采用,在国内由于多数使用单位均采用低压乙炔发生器,瓶装乙炔又未被采用,因而影响了等压式焊割炬的研制推广。现在由于中压乙炔发生器已被广泛采用,瓶装乙炔也已逐步推广,使用等压式焊割炬的条件已具备。 HG02—12/100型等压式焊割两用炬是由上海焊割工具厂研制,最 Isocentric torch has been widely used in foreign countries, in the country due to the majority of units are using low-pressure acetylene generator, bottled acetylene has not been adopted, thus affecting the development and application of isobaric welding torch. Now because of medium voltage acetylene generator has been widely used, bottled acetylene has also been gradually promoted, the use of isobaric welding torch conditions have been available. HG02-12 / 100 type isotherm welding and cutting dual-purpose torch is developed by Shanghai Hange Tool Factory, the most
