This is a dedicated part for resistance welding applications where the contactor must handle high inrush currents and repeated weld cycles without contact welding — the series name itself flags the anti-weld design.
Three-pole switching with a 1 N/O + 1 N/C auxiliary block means it controls the weld transformer primary while the aux contacts feed back weld-ready status or interlock the downstream PLC. The AF460W series is panel-mounted; plan for the physical footprint and power wiring clearance typical of a 460 A class weld contactor.
