The ISA-4000CR large-scale inverter for resistance welding, from Miyachi Unitek Corp., can produce 4,000 amps primary. It has five feedback modes, NEMA-style enclosure, built-in weld monitoring, a communications package, and a force control option. It also has fast rise times and high output stability, the company reports.
