WELDING & CUTTING TIPS

Welding Tips

Tips that are used for welding have a single hole in the end that directs the burning gas to the point that is being welded. A mixture of acetylene and oxygen is forced through this hole and ignited, causing a point of heat that is intense enough to cut through metal. Welding tips are manufactured in varying sizes, each one identified by a number. The higher the number, the larger the hole in the tip, and the thicker the metal it is able to cut. Welders need different sized tips. If they attempt to weld thin metal with an over-sized tip they will burn it, and if they attempt to weld thick metal with an undersized tip it will take too long to be efficient.

Cutting Tips

Cutting tips differ from welding tips in that the central hole in the end of the tip is surrounded by a series of smaller holes. The smaller holes serve as preheaters for the central oxygen flame that comes out of the central hole. As with welding tips, cutting tips are manufactured in different sizes to accommodate the gauge of metal that is being cut. To use a cutting torch, the operator applies the preheaters to the surface of the metal until it is got enough to glow red. He then activates the gas from the central cutting hole which removes the metal that has been weakened by extreme heat.
