Entron Controls for Resistance Welding EN1380

Butt or Flash Weld Controls with Anneal Sequence

The EN1380 Series Control is a microprocessor based resistance welding control. This control has been designed specifically for Flash Welding or Butt Welding with Upset and Annealing sequences. One outstanding feature (optional) of the EN1380 control is its ability to allow the operator concurrent adjustment during an initiated sequence (during Anneal time). Pilot initiation connections are dedicated for independent sequencing of Weld and Anneal sequences.

  • Store up to 50 UNIQUE SCHEDULES
  • Every parameter of each schedule individually accessible
    Each schedule can store 11 distinct and totally different parameters
    All schedules retained in memory with power off
    It is NOT NECESSARY to program functions not required

  • Additional Standard Features:
  • Priority Heat Select
    Contactor Failed Detection (Circuit breaker with shunt trip–optional)

  • Control can be INTERFACED with external Programmable Logic Control (PLC); Advanced interfaces available
  • Dedicated Clamp and Squeeze Output Valves
  • Meets or exceeds RWMA/NEMA standards

 

  • Specific Applications
  • Designed specifically as a dedicated microprocessor Butt or Flash Welding Control with associated Anneal Sequences.

  • Dedicated Initiations for Welding and Annealing
  • Optional Manual Adjust of Current during Anneal Sequences
  • Simple to Program
  • Push buttons and a three-step procedure make easy work of programming any welding schedule.

  • Two Year Warranty
  • A two year warranty is offered on all ENTRON parts and assemblies.
    Expert phone support and application service are available at no cost.
