    The Print parameter determines the output from the USB port at the end of each weld. If printing is off, there is no output; if printing is set to all, the WA2 outputs the results of every ½ cycle (AC) or 10 ms (DC) reading; if printing is set to summary, the WA2 outputs the average current and duration for the weld.
  • Page 14 The Stop parameter (not shown) can be used to capture a specific section of a long weld. The WA2 will capture 300 cycles (AC) or 3 seconds (DC) of welding prior to the Stop parameter. If DC mode is selected, the Blanking and Stop parameters are programmed in ms.
