Digital Phase Shift Current Control, 10 to 99% in 1% current steps, all weld current functionsIt is NOT necessary to program functions NOT required, program only functions required

Standard RWMA/NEMA Programmable FunctionsIncluding the following as examples:

Up Slope and Down SlopeSeam Weld (Continuous or Intermittent)Multi-Weld Count/Multi-Current SelectPre-Heat/Post-HeatPriority heat select individual or switch on the flySwitch weld schedule on the fly upon limit switch input

The EN1500 Series Control is a microprocessor based resistance welding control. It has been designed specifically forSeam Welding applications. One outstanding feature of the EN1500 control is its ability to allow the operator concurrentadjustment of weld heat intensity during an initiated sequence (this feature is optional).

• Store up to 50 UNIQUE SCHEDULESEvery parameter of each schedule individually accessibleEach schedule can store 11 distinct and totally different parametersAll schedules retained in memory with power offIt is NOT NECESSARY to program functions not required

• Single contactor circuitry; Process control outputs• Additional Standard Features:

Priority Heat SelectContactor Failed Detection (Circuit breaker with shunt trip, optional)

• Control can be INTERFACED with external Programmable Logic Control (PLC);Advanced interfaces available

• Meets or exceeds RWMA/NEMA standards
