Identifying the right cutting and welding tips
The tip of a welding or cutting torch is where the action is (see Figure 1 ). Welding tips usually produce positive pressure (higher than 1 pound per square inch ) and are used at equal pressures of acetylene and oxygen. These single-hole copper-alloy tips are attached to a torch handle... Read more...
