7.7 Wedge Removal

a. Disconnect the Cartridge Heater / Thermocouple Plug (4) (see Figure 2) from the
bottom of the controller cabinet.
b. Using 1/4" or 6mm hex wrench remove the front and rear Frame Shoulder Bolts (5)
(see Figure 6).
c. Hinge Side Frame up and install one of the Frame Shoulder Bolts into the front bolt
hole to hold the Side Frame in the open position. When the Side Frame is in the correct
open position there is a threaded hole into which the Bolt can be installed (1) (see Figure
8).
d. Rotate the Wedge Engagement Handle counter-clockwise until the Lock-In Plunger
drops into the Lock-In Hole on the Lock-In Disc.
e. Pull the Wedge Engagement Handle out far enough to insert the remaining Frame
Shoulder Bolt between the Handle and the Lock-In Disc (2) (see Figure 8). This holds
the Pinion Gear disengaged from the Wedge Rack so the Heater Assembly Can be
removed.
f. Release the Cartridge Heater and Thermocouple cables from behind the Heater Cable
Retention Disk (5) (see Figure 2).
g. Push down on the front of the Wedge Carriage Assembly while lifting up the tip of the
Wedge and slowly pull the Wedge Assembly out of the welder.
Note: To prevent the Wedge Timing from being changed do not disturb the Wedge
Engagement Handle position while the Wedge Assembly is removed from the welder.
