Show OXYACETYLENE'S USE IS SCIENTIFIC E. E. Darling, manager of the Monarch Mon-arch Motor company, 123-25 East Second Sec-ond South street, distributor of Prest-O-Lite, said yesterday that the process was ono scientifically developed for the -welding and cutting of metals. It involves the use of dissolved aeet.vlene and compressed oxygen, both gases in portable cylinders. Those gases, wll0n burned in -a suitable blowpipe, produce pro-duce a flame temperature of about b.l'ir degrees, ahr., which is callable , ol bringing metal to a molten state wiMi rapidny. . u The welding process is used when it j is desired to unite two pieces of metal i either in manufacturing metal prod-jucts, prod-jucts, in repairing broken parts or in adding new metal to the buiidin: of 'worn parts. In weldinpr the pieces of metal to bo joined arc h; at the point of welding to a ! state by tho oxy-acetyieue flam'. ' ing them to run together or fuse one homogeneous piece. Cutting wrought iron and settle se-ttle Prest-O-Lite process is operation that is easily neemij' The cutting process is hasoO M . fact that a jet of oxygen against a previously heat oil s!10' metal causes it to iimite null M away in the form of oxide- T ting is accomplished .by usinil 11 pipe, which provides an uxy-ai' flame for heating and a jet oi !' for producing the combustion or o tion. Anv intelligent workman, ''j Darling, having a fair 1;iio-1 the properties of metals can lMrt process in a short time. . |
