a great many oxy-acetylene welding out-fits manufactured in various types. A typical portablewelding outfit is shown in Figure 245. The type of blow-pipe shown with this apparatus is of sufficient capacity tohandle the widest field of oxy-acetylene welding opera-tions practicable. The welding apparatus proper consists of the weldingblowpipe (Figure 246) and two lengths of rubber hose,one for acetylene and one for oxygen, which are con-nected to acetylene and oxygen regulators. The Blowpipe.-—Designed for use in connection withcompressed gases, this style of blowpipe works on theequal pressure system; that is to say, both gases are de-livered to the blowpipe inlet at equal pressures and noinjector device is necessary. The gases are mixed nearthe handle and flow together along the full length of thestem, insuring a perfect mixture by the time the tip isreached. The stem is fitted to the mixing chamber bymeans of a union nut, which permits the operator to 314 SHEET METAL WORKERS MANUAL

Line adjustmentsof the oxygen and acetylene supplies are made by controlvalves in the blowpipe. For continuous light welding work the smaller blow-pipe, shown in Figure 247, is more suitable, permitting
