Wedge Timing Definition

Wedge timing is the position of the Wedge in its Engaged/Welding position in relation to the
Engagement Handle Lock-In Plunger to Lock-In Hole position. If the Wedge timing is off
the ability to adjust the welder through its full range of adjustment is compromised. Full
range travel is between the two positions of the Wedge in the Engaged/Welding position and
the Wedge in the Retracted/Loading position.

Wedge Re-Timing

Loosen the two Lock-In Disc Hold-Down Screws (2) (see Figure 6). Position the Lock-In
Disc so the two Hold-Down Screws are centered in the arced grooves of the Disc (see Figure
6). Tighten the Hold-Down Screws. Pull out the Engagement Handle as far as possible,
approximately 5/8" (see Figure 7) which disengages the Pinion Gear from the Wedge Rack
and rotate the Engagement Handle approximately 15 degrees clockwise. Release the Handle
back in and rotate handle counter-clockwise moving the wedge towards the Nip Rollers.
This resets the engagement of the Pinion Gear to the Wedge Rack by approximately one gear
tooth. Repeat this process as many times as necessary until the Lock-In Plunger drops into
the Lock-In Hole on the Lock-In Disc and the tip of the Wedge has approximately 1/8"
clearance between it and the lower nip roller. The Wedge has now been re-timed.
