Adobe_PDF_file_icon_32x32 EN1000 Spec Sheet 

Multiple Schedule/Multiple Sequence Resistance Welding Controls

  • Simple to Program
    Push buttons and a short three-step procedure make easy work of programming any possible welding schedule.
  • Quality Tested to Performance Extremes
    Each unit is tested to insure maximum performance at customary operating levels. This Entron resistance welding control has consistently offered an excellent performance history.
  • Application Flexibility
    Designed for use with single phase welding machines, rocker arm and press type welders, brazing and robotic equipment, and special machines.
  • Normally Stocked at TJ SNOW
    This control is normally stocked at TJ SNOW and our service department is fully trained to do board level repairs on the ENTRON 1000 Weld Control.
