Products

High Force Servo Weld Head - 73 Series

MIYACHI UNITEK’s 73 Series Weld Head is designed for use in either automation or bench-top welding. It offers fast and repeatable electrode motion control for a wide range of resistance welding applications. The weld head features an easy-to-program servo-motor controller that allows the electrode position and speed to be precisely programmed and for up to 32 different weld schedules. The head can also be configured in either an inline or parallel-gap configuration or specifically configured for automation applications.


Specifications

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

 

High Precision Weld Head - MFP25

MFP25 is the newest member of MIYACHI PECO’s modular weld head series. It is designed to provide customers with the widest possible range of options and variations while emphasizing quality, efficiency and serviceability.

The low force, servo-motor driven MFP25 weld head with linear drive is specifically designed for use in the MIYACHI PECO AWS3 Active Welding System.


Specifications

  • Low force range: 1 N to 25 N
  • Compact, robust design for automation integration
  • Servo-motor driven
  • Closed-loop force control
  • Programmable electrode speed, force and position deliver flexibility and ease of use
Low Force Weld Head - MFP60

The new servo-motor driven MFP60 motorized high-speed, low-force weld head is specifically designed for precision, automated, high-speed applications found in the lighting, automotive, tooling, and electronics industries.

Its compact design makes it easy to integrate into existing production lines, but it was specifically designed for use with the MIYACHI PECO AWS3 Active Welding System.


Specifications

  • Force range: 20 N to 60 N
  • Compact design for automation integration
  • Servo-motor driven
  • Closed-loop force control
  • Programmable electrode speed, force and position

 

MFP1 and MFP2 - Motorized spot welding heads for automation

Designed for a wide range of automated or benchtop applications, the servo-motor driven MFP1 and MFP2 motorized weld heads deliver outstanding weld process stability and repeatability.  Force ranges are up to 220 N and 600 N, respectively.

Maximum reliability and ease of maintenance ensure low cost of ownership and a very long operating life.


Specifications

  • Force range 50 N to 600 N
  • Max electrode stroke 25 mm
  • Servo-motor driven
  • Integrated displacement
  • Quick-change electrode holders
  • Water-cooled electrode holders
  • Optional stand for benchtop use

 

Servo Motor Driven Weld Head - 70 Series

Designed for use in automation or benchtop welding, MIYACHI UNITEK’s 70 Series Weld heads offer stable, repeatable electrode force for a wide range of resistance welding applications. Two different models are available, each equipped with an easy-to-program, state-of-the-art servo motor controller which allows the electrode positions to be precisely programmed and a speed of up to 32 different weld schedules.


Specifications

  • Controlled, fast, repeatable servo motor actuation
  • Extremely low-end force control (0.25lbs)
  • Remote control I/O and PC communication
  • Displacement and force options
  • "Soft Touch" part clamping
  • Unitip and blade thermode option
