a. While adjusting the Wedge engagement position refer to Diagram 2 and Figure 6. Pull
out the Wedge Engagement Handle Lock-In Plunger (1) (see Figure 6) and rotate the
Handle to a central position between the two Hold-Down Screws (2) (see Figure 6).
Loosen the Hold-Down Screws and rotate the Wedge Engagement Handle counter-
clockwise until the Lock-In Plunger drops into the Lock-In Hole (3) (see Figure 6).
The Lock-In Disc (4) (see Figure 6) should now rotate with the Engagement Handle.
b. Slowly turn the Engagement Handle to position the Wedge so the distance between the
upper tip surface of the Wedge and the Upper Nip Roller is the same distance as
between the two Nip Rollers. This distance will be equal to twice the thickness of the
material to be welded. This same clearance should be maintained between the lower
tip surface of the Wedge and the Lower Nip Roller.
