The Weldmark® by Victor® Acetylene Harris 6290 series Oxy-Fuel Size 4 Cutting Tip has a 3-6 inch cutting capacity. This general purpose Harris 6290 series tip is 0.8" long and 3.3" wide, and comes in one piece. It is ideal for hand and machine torch cutting. It is capable of cutting 9-12 inches per minute. It's designed for use with Acetylene. The max Acetylene pressure is 15 and the max oxygen cutting pressure is 75. Oxy-Fuel cutting is a thermal cutting process utilizing oxygen or fuel gases to cut through metals such as mild steel. In this process, the torch heats the steel to its ignition temperature, after which oxygen is directed to the cutting point, burning it into a metal oxide. A stream of gas blows the metal oxide away from the work area, resulting in a clean cut.
