gas cutting nozzle is best for cutting workpieces with a thickness of 225-300 mm. It can be used with oxygen at a pressure of 6.0 bar and propane at a pressure of 0.5 bar. The nozzle is made of durable materials and features a reliable design, making it ideal for heavy-duty use. The 3/64 Inch Gas Cutting Nozzle from MAPP is best for welding and soldering. PNM Nozzle The PNM nozzle is highly appreciated for the extra safety measure it employs. It limits the mixing of gases to the 3 seat nozzle only thereby eliminating any possible chance of a backfire or a flashback hence ensuring work safety. It is produced for use with liquefied petroleum gas and acetylene gas fuels. It comes in two pieces for LPG use and a single piece for acetylene use. Similar to its two counterparts discussed above, it is available in various sizes. Table 1.1 above, clearly illustrates the sizes available in the market.
