The Weldmark® by Victor® Acetylene Airco® style 144 series Oxy-Fuel Size 1 Cutting Tip has a cutting capacity of 0.50 inches. This general purpose Airco® series tip is one piece. It is ideal for hand and machine torch cutting on 4700 series machine torches. It is compatible with 3790, 4800, 5700 and 5800 cutting attachments, and is capable of cutting 18-21 inches per minute. It's designed for use with Acetylene, with a max Acetylene pressure of 3 and a max cutting oxygen pressure of 30. 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.
