SR-073A High Force Motorized Servo Weld Head – Opposed Electrodes

Designed for use in either automation or bench-top welding, the Model 73 weld head offers stable, repeatable electrode force for a wide range of resistance welding applications. The weld head features an easy-to-program servo motor controller that allows precise programming of electrode position and speed for up to 32 different weld schedules. The head can be configured in either an inline or parallel gap configuration, or specifically for automation applications.

  • Programmable speed and positions
  • Controlled servo motor actuation eliminates over-force
  • Force range 15 to 110 lb
  • Durable and robust head design
  • Displacement and force options
  • Comprehensive I/O
