Weld Heads

MacGregor precision weld heads and modules provide a flexible and robust micro welding head with excellent performance throughout the force range specified. All models are based upon a unique module design that can be fitted with force and displacement sensors. The modules are very compact and narrow, making them ideal for demanding automation applications.

The Universal Series of welding heads offers the user a tool-free adjustment of the weld head height and base plate assembly. A very low-moving mass and low-friction bearing system set these apart from conventional designs.

The welding heads are available in three basic configurations:

  • Opposed: In-line welding electrodes with single welding head and fixed lower electrode.
  • Parallel Gap: Parallel welding electrodes mounted in a compliant tip assembly.
  • Twin: Parallel welding electrodes with twin welding modules for individual force control and compliance

Constant Force Weld Heads

The Constant Force Weld Head delivers intelligence, functionality and precision accuracy for small component micro joining.
Our Constant Force Weld Heads use precision 20 mm linear perpendicular electrode travel for sensitive and fine applications such as hybrid circuits, cross wire welding, fine wire terminations and parallel gap welding on force sensitive substrates.


Specifications

  • Precision force control with intelligent, real-time weld pulse limiting.
  • Precision 20mm linear perpendicular electrode travel for sensitive and fine applications such as hybrid circuits.
  • Built-in real-time force monitor.
  • Optional PC link connection for quality control and data collection.
  • Standard parallel gap with option for opposed configuration.
  • Infinitely variable back support and slide.

 

High Force Weld Heads - HFW-700P, 700N

The HFW-700P is a fully adjustable high-force pneumatic welding head that incorporates a low-mass adjustable welding module with a robust pneumatic actuation system and housing.
Welding force is readily adjusted between 100 N and 700 N via an ergonomic lockable adjustor, facilitating precise and repeatable resistance welding.

The HFW-700PM welding module is also offered as an independent component for automation applications.


Specifications

  • Fine force adjustment in the range 100 N – 700 N.
  • Overall actuation stroke extends to 30 mm.
  • Narrow footprint with adjustable height.
  • Positional upper and lower mechanical stops.
  • Optional force sensor & displacement sensor.
  • Light-weight design

 

Weld Head Modules

Our precision ultra-low inertia weld head modules can be used standalone mounted on third-party application product or may be supplied as bench-mounted units either with fixed or variable
height back supports. A large range of custom and standard electrode holders are available to suit almost any application.

The precision modules combine an integral force adjustment control with options to fit force and displacement monitoring transducers for use with process feedback-based power supplies.
MacGregor Welding Systems delivers standard modules (2 - 70 N force range) and high-force modules (10 - 500 N force range)


Specifications

  • Force range: 2 -500 N force range
  • Stroke: 25 mm
  • Compression: 10 mm
