Universal 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:

• Very low inertia delivers fast process response and rapid settling.

• Suits all drive systems : motor, pneumatic, manual.

• Proven, rugged design ideal for automation.

• Narrow footprint permits high density mounting in confined areas.

• Options for built in force and displacement sensing transducers.

• Automotive components

• Hot staking and crimping

• Solar cell assembly

• Lamp manufacture

• Conductive material welding

• Contact welding

• Sensor and component welding

• Thermode staking applications

• Battery tab & pack assembly

• Gold ribbon welding

• Pneumatic Automation

SMART Series - High speed electronic servo spot weld heads

SMART Series electronic servo weld heads seamlessly integrate with SMART series DC spot welding power supplies to provide total process definition and control with one simple solution.  Process parameters can be defined at the machine or via Ethernet and are fully closed loop controlled to ensure ultimate repeatability and accuracy.  

Real time measured parameters are recorded and can be analysed at the touch of a button via the integral SMART SPC graphical functionality.

Typical application include high end medical, automotive and aerospace manufacturing.
