MacGregor reveals pulsed-arc micro joining systems

The MacGregor PA range will be offered in a choice of three variants, comprising the 20A PA20, 40A PA40 and 60A PA60, all available with optional gas control.

All models are suitable for a wide range of small wire coil terminal applications, including relays and solenoids, ignition coils, voice coils, microphones, motor terminals, transformers, sensors, inductors and motor terminators, along with numerous other 'wire-to-pin' and 'wire- to-wire' joining.

Enamelled, stranded or plain wires can be joined to a variety of connection pins, with no need for prestripping or cleaning prior to the weld process.

Offered in an extensive choice of different current settings, the range is fully programmable and incorporates linear-based technology to produce precision pulsed-arc welds to an accuracy of around 1 per cent.

Key features include a colour screen, two and four output options for automatic single- or dual-pulse weld profiles, an inbuilt memory for storing up to 99 different weld profiles, graphical information to show the weld profile and the last weld, and a high and low limiter to control the amount of power used.

The on-screen touch keypad eliminates the need for moving keys and switches, making the equipment even more versatile in hostile environments, where there are risks from chemicals, dust and debris.

A standard design feature ensures that the PA range has low RF radiation, which is especially important where computer equipment and other RF-sensitive items are being used.

The PA series is sold by MacGregor Welding Systems as a stand-alone machine, and can also be integrated by the company into a full turnkey automated pulsed-arc line where required.
