SX-6015 Subsonic flame wire spraying system is the wire air spray gun, which uses oxygen and acetylene flame as the heat source of spraying,compressed air as the power source of the wire feeding to spray.Because the compressed air is the power of wire feeding, it needs higher requirement for the stability of the compressed air pressure and flow .SX-6015 subsonic flame spraying wire system is combined with the characteristics of high speed and medium speed of conventional flame spray gun.It Optimizes gas flow control system, which can be chosen the high-speed spray gun to spray low melting point materials ( 3mm zinc wire and aluminum wire), also can be chosen with medium speed spray gun to spray high melting point materials(2mm steel carbon wire,stainless steel wire,copper wire,etc.).SX-6015 subsonic flame wire coating system is suitable for spraying repair and surface treatment in small workpieces and small area,it is the effective complement of thermal spraying equipment.
