Entron Controls for Resistance Welding EN1380

Adobe_PDF_file_icon_32x32 EN1380 Spec Sheet 

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.
