Programmable Pulsed Arc and Linear DC Resistance Spot Welding Power Supplies

Amada Miyachi, Inc. (Monrovia, CA) offers complete local product and sales support for the PAxxP range of programmable pulsed arc power supplies manufactured by their sister company MacGregor™ Welding Systems Ltd. (Bury St Edmunds, UK). These linear DC precision arc-welding units are ideal for a range of contactless, high-speed, solder-free coil and wire termination applications, including connector pin termination, micro wire pin connections, tungsten inert gas (TIG) ball and wire combination, and coil termination. Available for both single output laboratory use and multi-output high speed automation applications, the PAxxP units use state-of-the-art closed-loop electronic arc control circuitry to deliver constant current arc control to within one percent accuracy with currents up to 100 amps. Welding currents and profiles are fully programmable for upslope, peak, and downslope. Real-time graphical oscilloscope feedback provides process monitoring and quality assurance pass/fail criteria. The units provide 99 memory locations for either single or double pulse weld profiles.

The PAxxP range features an easy-to-use intuitive color touch screen with graphical weld tracing. They offer single phase, 115V AC or 230V AC operations, and an isolated RS232 port for PC or PLC programming. Weld limits for voltage and current provide instant feedback on the weld process.

Amada Miyachi also offers complete local product and sales support for MacGregor DC1013-T and DC613-T Series of linear DC resistance spot welding power supplies that are typically used in aerospace, medical, and electronic assembly applications, DC1013-T and DC613-T units are ideal for butt welding fuses, welding components to lead frames, gold ribbon bonding, and welding fine wire to pads. High speed automation and communication ports offer users full remote control capability. The DC1013-T and DC613-T Series incorporate statistical process control (SPC) data collection and reporting capability via Ethernet. The high performance 1,000 ampere (A) precision linear DC spot welding power supplies combine touch panel integrated database process control and monitoring with a high accuracy, zero ripple linear transistor output stage that delivers ultra-fast 10 micron per second (µs) dynamic process response rates, with absolute closed loop 1 A incremental accuracy and repeatability.

Offering high speed, ultra-low ripple closed-loop output control, the DC1013-T and DC613-T Series provide consistent welding process definition and control. Operators can select constant current, voltage, and power modes with programmable multi-pulse combinations in 1 A steps up to 1,000 A. Programmable part and weld checking is coupled with optional displacement and force limit checking. The DC1013-T offers three-phase operational variants, while the DC613-T supports single-phase operations. Operators have access to full TCP/IP Ethernet interfacing to internal and external SPC database systems. They can easily view both pdf and text format work instructions and process manuals with weld schedules and can view image files with weld schedules for quality control and process checking. Other useful features include three USB ports for use with a memory stick, mouse, keyboard, or servo head drives; and SMART weld head force control within weld schedules.
