The Weldmark® by Victor® Propane/Natural Gas Harris style 6290NX series Oxy-Fuel Size 5 Cutting Tip has a 6-8 inch cutting capacity. This general purpose Harris 6290NX series tip is two pieces with a spline insert. It is ideal for hand and machine torch cutting. It's designed for use with Natural Gas and Propane. The max Propane pressure is 15 and the max oxygen cutting pressure is 80. Oxy-Fuel cutting is a thermal cutting process utilizing oxygen and 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 molten metal. A stream of gas blows the molten metal away from the work area, resulting in a clean cut.
