Inverter Racks Four, Six or Eight Pack-Configurations Conveniently grouped in an industrial, portable package, these new inverter racks are designed for use on jobsites that require a number of welding power sources for multiple operators. The inverter racks come in four or six packs with the multiprocess Invertec V350-PRO factory rack model, or in four or eight packs with weather-protected Invertec V275-S for stick and TIG welding. They are constructed of heavy-gauge square tubular steel and are the only racks on the market to offer a standard main disconnect switch and IP23S-rated power sources, says the maker.
