The user-friendly computer and easy to understand prompting style menu approach has been designed to make the training, set-up and operation short and simple. The only necessary information is the resistance range of the part and the temperature at which the bond coat will activate. Everything else is automatically measured and calculated.

There are no meters or scopes for the operator to interpret. All decisions relating to the acceptability, current, bonding time and temperature of the part are made automatically. To begin the bonding process you simply select the temperature cut-off limit at which the part will bond. The operator than loads the part into the tester and closes the safety cover. At the end of a successful bond cycle, the part can be removed from the tooling.

The test results are displayed on-screen. (See Illustration below) The graphical screen displays actual resistance and temperature as the winding is being heated, elapsed bonding time, a graph of temperature/resistance vs. time, the temperature and resistance cutoff points, the voltage and current being applied, and the real-time temperature from sensor, if installed. Test results will be held, on-screen, until the operator opens the safety slide cover. The entire software program has a clear and precise fault messaging system.

The operator may change from one part to another by simply selecting a new part number from the stored parts within the system. The limits that were established for the part are also retained, which eliminates the need for re-entering limits every time the part is run.

Production counts can be viewed on screen at any time through-out the production run.

An uninterruptible power supply (UPS) protects the computer from power failure. If there is a power failure, the UPS will switch to battery mode, sound a audible alarm, shutdown the bonding software, shutdown Windows and finally shutdown the computer. This assures that the computer will be shutdown properly even in the event of a power failure.

The plug in modular layout make circuit troubleshooting easy. Access to the inside components is through the rear door and a lower front panel. The cabinet is interlocked for the operator’s protection.

The built in calibration box is located inside of the cabinet and is easily accessible from the rear door. Calibration of the resistance and constant current test instrumentation is simple and the instructions are easy to follow.

The graph above displays the temperature and resistance of the coil under bond in relation to the elapsed time. The resistance plot is an orange line and the temperature plot is the tan filled area. If a dwell time is set, two black lines will appear to indicate the beginning and the end of the dwell time. After the bond process is completed, the cursor can be dragged along the resistance plot to display the resistance and temperature for any point during the bond process.
