    CHAPTER 2: GETTING STARTED 2 Set the POWER switch on the Weld Head Control rear panel to the ON (up) position. The Weld Head Control will automatically run a self-test cycle, during which it:  Determines the downstop position (DNST) of the opposing electrode. It then resets the DNST so that it is calibrated as 0.000.
  • Page 26 CHAPTER 2: GETTING STARTED Figure 2-5 shows an example of setting new UPST and SRCH positions that are suitable for a typical combined workpiece thickness of 0.020 inch (0.51 mm). A space of 0.25 inch (6 mm) between the upper electrode tip and the workpieces will set the UPST position at 0.270 inch (6.8 mm). A nominal space of 0.25 inch (6 mm) reduces the travel time for the upper electrodes to reach the workpieces.
