MARINE REvieEw—August, 1934 WHY the Oxweld C-24 is a Better Cutting Blowpipe .. . Cutting Valve The C-24 cutting valve has no packing or stuff- ing box nuts. Instead a double flange rubber bushing is mounted on the valve stem. This feature is found in no other blowpipe. Oxweld Patented Seat Protector - Thechromium plated C-24 nozzles have patented conical seats which are so designed that they are not easily marred. Nozzle Drilling C-24 nozzles are drilled at a slight angle so that the heating flames meet the cutting oxygen jet at the point that is to be preheated. This makes a concentrated point of heat that insures a fast start and a clean kerf. Ball Needle Valves In the Oxweld ball seat needle valve the hard- ened, highly polished stainless steel ball frees itself of all particles that might prevent a gas tight seat. Rear Body All gas controlling parts of the C-24 are con- tained in the pressure forged rear body and not inside the handle. There are no adjustments to make.
