Pulsed arc welding power suppliesClick image to enlarge

Amada Weld Tech has announced the availability of pulsed arc welding power supplies for precision joining applications, ensuring control and repeatability.

These supplies range from lab models with customizable options, to production machines offering streamlined features. The items are designed and built in-house, from equipment for small-scale manual production to fully automated systems. 

Each system solution is available with easy-to-program PLC or industrial PC software. Also, each system benefits from SPC integration, automatic alignment, advanced user interfaces, remote diagnostics, CNC motion, robotics, and product transport systems, as required.

The systems are available in 1, 2, 3, and 4 output models to allow for a single power supply in high-speed production automation. Single output standard models include the PA-60P and PA-200P. Multiple output models are available from 20-60 amps.

Each unit produces a pulse of accurately controlled current. A specially developed arc start system incorporates a high voltage DC impulse, operating with a stabilizing power supply. This ensures consistent arc ignition with minimal radiated interference. All models offer gas flow control and voltage monitoring, to detect arc failure.

Closed loop techniques ensure stable outputs independent of temperature, cable lengths, and mains supply variations. Amada accomplishes this through transistorized output control and an analogue feedback and drive circuit. This control system responds rapidly to process changes and stabilizes output, ensuring consistency.
