Yaskawa Motoman's new Universal Weldcom Interface Click image to enlarge

Yaskawa Motoman has introduced Universal Weldcom Interface (UWI), a pendant application that enables full utilization of the capabilities of select Miller and Lincoln Electric digital welding power supplies.

UWI enhances control of all weld processes and parameters including voltage, amperage and wire feed speed through a common user interface for either brand.

UWI can filter weld modes based on process type, wire size, wire type and gas type. Up to 16 unique processes from the power source library can be defined for access within the interface, and up to 1,000 custom arc files with specific processes and parameters are available for use in motion programming.

Up to six weld process parameters in a weld sequence – such as Pre-Flow, Start, Main, Crater and Finish Condition – can be set. Standard functions such as Arc-Retry, Arc Monitor Data Enable, Re-Start and Weld Line Shift are utilized. A new Dual Pulse function allows alternating between MIG weld parameters and settings for positive TIG-like cosmetics.

Weld settings on the UWI use terminology that matches the user’s preferred power source. Standard ARCON commands are used, eliminating the need for complicated macro jobs. Programming with arc file interface or inline instructions is supported. Graphical help screens explain terminology and functions.

The Universal Weldcom Interface is compatible with arc welding performance tracking features native to the power source. Live weld status is presented on the IF Panel display or Graphic Arc Monitor. Weld data can be exported for use in PLCs and part quality serialization. Arc Monitor results from Miller Insight Centerpoint or Lincoln CheckPoint Production Monitoring can be used for alarms or reported to PLCs. Hardware communication for diagnostics is also monitored and logged.

UWI can be used on up to four AR-series arc welding robots with YRC1000 controller (YAS2.81.00-00 firmware or higher). It is compatible with the Miller Auto-Continuum 350 or 500, or the Lincoln Power Wave with ArcLink XT. A simplified networking utility enables setup between the robots and the welders.

Additional features and global power source compatibility are planned in the future.

Unique machining concept: Multi-task turning

Mazak's Orbitec 20 is a unique machine originally developed as a customized solution for a customer application.

Fast setup with new punch holders

Wilson Tool launched an innovative, yet simple approach to punch holding at the recent FABECH 2011 show in Chicago, IL.

Improved tool-spindle connection rigidity

When machining tough materials like titanium, there is a need for a spindle connection that makes the best use of available power.

Better welding performance for sub arc apps

ESAB Welding and Cutting Products’s new Aristo 1000 AC/DC power source for sub arc welding is an inverter power source that can be connected to three-phase input voltage supply (from 380 to 575V at 50 or 60 Hz).
