It should be added that apparatus employing acetylene in solu-tion and hydrogen in tanks is best suited for use in work requiringa portable installation and in establishments where continuous useof the process is not required; while it is more economical to use aninstallation with generators for acetylene and hydrogen where thework is to be continuous, or where the applications are many enoughto allow continuous operation of the generating apparatus and areperformed upon parts so light

The Cutting of Metals. We come now to the cutting of metals, or more exactly of ironand steel, by oxygen. It is well-known that iron burns easily and rapidly in an atmos-phere of oxygen gas. The experiment is familiar in every coursein physics and chemistry. The same phenomenon occurs when a jetof oxygen is directed upon iron heated to a bright red—that is to.
