新型金属焊割气是原乙炔气(即电石气)的替代产品。其技术关键攻克了氧气与任何油类及易燃品接触会自燃自爆的禁区,开辟了多种原料生产金属焊割气的新途径。其设备投资是乙炔厂的10%,生产成本比乙炔低50%;焊割效果与乙炔一样,使用工具、操作方法一样。用耐压钢瓶装,无需抽真空和 The new metal welding gas is the original acetylene gas (ie, calcium carbide gas) alternative products. The technical key to overcome the oxygen and any oil and flammable contact will spontaneous self-ignition restricted area, opened up a variety of raw materials to produce a new way of metal cutting gas. Its investment in equipment is 10% acetylene plant, production costs lower than acetylene 50%; Hange effect and acetylene, the use of tools, the same operation. With pressure cylinder loaded, without vacuum and
