Oxy-fuel torch cutting on stainless steel and non-ferrous materials is difficult, if not impossible. These metals tend to resist burning action. The oxides that form on top of some metals such as stainless steel are tough and won’t melt, so the oxygen jet cannot get through it. Other metals such as cast iron and non-ferrous metals burn with less heat or they tend to cool the cutting zone. The solution is to make the flame hotter. To do this, QCC’s powder cutting tips inject iron powder into the oxygen stream. The extreme heat created by the burning powder makes it possible to start cutting (flying starts) without pre-heating. The fluxing action of the burning powder enables the oxygen stream to oxidize the base metals continuously, just as in cutting carbon steels.
