For hardfacing on dies, punches, shears, debarker knives, mill cutters and planing tools.
Use AC or DC Reverse [+] Polarity. Use the grinding method or remove fatigued metal using the EAGLE 188.
Use lowest effective amperage while maintaining a medium arc length making either stringer beads to reduce heat input. On low carbon steels it may be necessary to use a minimum of three layers to overcome dilution. When welding on tool steel, pre-heat the part to 1000°F.
The EAGLE 646 is a high quality alloy for use on high speed and hot working steel.
