These single-hole copper-alloy tips are attached to a torch handle equipped with a mixer that mixes the fuel with the oxygen, much like a carburetor in a car mixes the gas and air.įigure 1 Welding tips mix oxygen and fuel, and then the mixed gas is pushed through the welding tip and is burned at the tip end. Welding tips usually produce positive pressure (higher than 1 pound per square inch ) and are used at equal pressures of acetylene and oxygen.
The tip of a welding or cutting torch is where the action is (see Figure 1).
