its furthest IN position (toward the Head) to its furthest OUT position. How this
can be done will vary from Weld Head Model to Weld Head Model.
5. Press Sequence Start and after prepurge measure the full Oscillator movement. It
should be 0.500 inch +/- 0.005. If out of tolerance adjust TR4 on the center plate.
