17 Insert the force gauge between the two electrodes. Press right arrow key [ ► ]. Adjust potentiometer
R118 for a reading of 10lb, ± 0.1lb (4.54 kg, ± 0.04 kg) on the force gauge.
Note:
Make certain that the force gauge is absolutely perpendicular to the electrodes. A holding
fixture installed in the lower electrode holder is recommended.
18 Press right arrow key [ ► ]. Adjust potentiometer R113 to zero the indicator bar to center scale, and
the 4-digit reading to 0000, ± 3.
19 Press right arrow key [ ► ]. Verify that the reading on the force gauge is 2lb, ± 0.3lb (0.91 kg, ± 0.14
kg). If the force gauge reading is out of tolerance, press [RUN] to exit and restart calibration from
step 5 of this procedure. If the reading is within tolerance, press right arrow key [
► ] and continue.
20 Use the up and down arrow keys to adjust the force gauge reading to 2lb, ± 0.2lb (0.91 kg, ± 0.09 kg).
21 Press right arrow key [ ► ]. No more adjustments are necessary. Remove the force gauge from
between the electrodes. Press [RUN] to exit the calibration screens and save the calibration settings
in memory. The head will go through its start-up routine.
22 After the Weld Head Control screen has reached the MAIN MENU, set the POWER switch to the
OFF position and disconnect the AC input power.
23 Apply Glyptol to all of the adjustment potentiometers, and replace the Weld Head Control cover. The
calibration procedure is now complete.
