WS2003

Constant Current Controls

The WS2003 is an advanced controller designed to control a wide range of resistance welding machines. Because of its highly modular construction, it lends itself to integration into customer control cabinets and retrofits, as well as completely self-contained applications. The variety of "add on" accessories makes this controller one of the most versatile on the market.
