The WeldAware Monitor is able to monitor the following:

• Secondary current profile,
• Secondary voltage profile,
• Secondary resistance profile,
• Secondary power profile,
• KiloAmp-seconds,
• Kilowatt-seconds,
• Weld time,
• Pressure (upgrade), or
• Force (upgrade).

When a weld is made, current flows through the secondary circuit. The monitor’s secondary coil senses the current flow and causes the monitor to collect data from each of its installed sensors: current coil, voltage probes, force or pressure sensor. The data are collected for as long as nearly 2 seconds and are periodically parsed into time slices of duration appropriate for the particular welding process being monitored. When the monitor is taught as a weld is being made, an error band of +/- 10% is placed around the profile of each variable being monitored. For all welds made subsequent to teaching, the monitor compares the weld profile for all monitored parameters with the limits developed during the teaching process. If anything is out of limits the unit’s red light turns on and stays on until the monitor is reset.

None at all. Out of the box the WeldAware Monitor is ready to be configured (by setting a jumper or two) to meet the user’s requirements. It can also be interlocked to the machine, if desired, to prevent welding from continuing when an alarm occurs until the reset button is pressed.

Absolutely! The unit is equipped with an output that turns OFF when an out-of-limits condition occurs and an input that can be used to clear the alarm condition of the output and toggle the output ON and OFF so that the PLC can check the operational integrity of the monitor before each weld is made. In addition, the output toggles OFF for approximately 50msec at the end of each weld so that the PLC can verify that the monitor is still on line and/or recognize that a weld has been made.

Nothing. The monitor stores the limits immediately in non-volatile memory. Simply turn the monitor back on and continue welding.

The monitor has jumpers that allow the user to select error bands of +/- 10%, 15%, 20%, or 25%. For a small customization fee, a new monitor can be delivered with a different error band of the customer’s choosing. For the same customization fee plus a shipping and handling charge, any monitor can be returned to the factory to have the error band modified from standard settings.

WeldComputer’s design engineers have worked industriously to develop a monitor that is low-cost, easy to install, and simple to use. The WeldAware Monitor has met those objectives and the documentation provided with the monitor contains all the information a user needs to learn in a very short time how to install and operate the monitor. Training should not be necessary, but WeldComputer does offer a complete suite of resistance welding training and consulting services.

In addition, WeldAware Monitor customers have the option of returning their system(s) to WeldComputer for a standard weld evaluation that can be used to guide weld improvement.

Simply teach the monitor until you produce a weld that is acceptable. Every time the monitor is taught it discards its old limits information.

Yes. The system includes a key switch that toggles between the Teach Mode and the Operate Mode. Simply turn the switch to the Operate Mode and remove the key to lock out unauthorized changes that could affect the upper and lower limits.
