The durable WildCat Burner has an extraordinarily powerful flame that can be used with borosilicate and soft glass. It works equally well with propane and natural gas with oxygen. The WildCat features sturdy brass casing and 19 stainless steel fuel ports. It uses a ball joint for articulation of the burner head and remotely placed metering valves that allow for a wide range of control. It has incredibly efficient combustion and uses the highly effective "vortex" cooling system which uses oxygen from the burner to pull air through the casing.
