cutting
nozzles a cutting nozzle has two main functions: ? to guide the heating flame ? to guide the cutting oxygen jet the heating flame's task is to: ? heat a point on the workpiece to its ignition temperature ? retain the ignition temperature at the surface during the cutting process ? clean the surface of impurities in order to facilitate the cutting oxygen jet's contact ? protect and support the cutting oxygen jet the cutting oxygen jet's task is to: ? strike the cut surface with high levels of gas purity and precision ? burn iron to produce iron oxide ? blow the iron oxide and other slag products out of the cut important! maintenance and choice of cutting nozzles in order to achieve the best cutting results, it is extremely important for the cutting nozzle to be cleaned and maintained regularly. the choice of cutting nozzle is primarily dependent on: ? type of fuel gas, normally acetylene or propane ? type of cutting torch, normally for flat-sealed or 3-cone sealed nozzles ? type of cutting; scrap cutting or quality cut with the highest possible cutting speed after that, select nozzle size according to the material thickness to be cut. there are various cutting nozzles for special tasks such as gouging and rivet cutting. function and maintenance. injector
