Abstract
Abstract A welding tip for a cutting torch is made by forming a cylindrical head with a central stem at one end and an axial socket in the other end, and a ring of drilled passages extending from inlets around the base of the stem to the inner end of the socket. A solid rod with an inner end portion that will fit snugly in the head socket is drilled to provide it with a single passage lengthwise through it to form a nozzle. This passage is reamed to taper it from the inner end of the rod substantially to its outer end and to provide the large end of the passage with a diameter great enough to register with the inner ends of all of the head passages when the nozzle is inserted in the socket and sealed therein.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
208 words
A welding tip for insertion in a cutting torch socket that has a reduced inner end portion provided with an oxygen inlet port and has an internally threaded outer end portion for a tipencircling ring nut, the side wall of the socket being provided with a fuel gas inlet port between the oxygen port and said outer end portion, the welding tip comprising a cylindrical head provided with an axial socket extending inwardly from one end, a solid stem of smaller diameter than the head projecting axially from the center of the opposite end of the head and forming an annular shoulder between the stem and the periphery of the head, said shoulder being provided with a plurality of fuel gas inlets arranged in a circle around the stem, the stem being of a size to plug the reduced inner end portion of the torch socket and position said fuel gas inlets outwardly from the fuel gas inlet port, and a nozzle having an inner end portion fitting in said head socket and sealed therein, the nozzle having a single longitudinal passage therethrough tapered toward its outer end, and said head being provided with passages connecting said circle of inlets to the inner end of said nozzle passage.
