OK AristoRod 55
OK AristoRod 55 is a 0.5Cr-0.5Ni-0.2Mo-alloyed, bare, solid wire for the GMAW of high strength steels. OK AristoRod 55 is treated with ESAB’s unique Advanced Surface Characteristics (ASC) technology, taking MAG welding operations to new levels of performance and all-round efficiency, especially in robotic and mechanised welding. Characteristic features include excellent start properties; trouble-free feeding at high wire speeds and lengthy feed distances; a very stable arc at high welding currents; extremely low levels of spatter; low fume emission; reduced contact tip wear and improved protection against corrosion of the wire.
