Hot Wedge Heat System Adjustments
A note before beginning; the wedge should be a bit loose (3/16 inch of play). Begin by
setting the Master Speed to zero and closing the weld rollers.
First Alignment Step
When the wedge arm swings in and drives forward, it is imperative that the point of the Alignment
Pin fits into the Recess of the wedge arm. Check this by engaging the Drive Foot Pedal. If this is
OK, move on to the second alignment step. If not, loosen the nut on the pin and adjust the pin left
to right. Set the proper depth and retighten the nut.
Second Alignment Step
The tip of the wedge must be the same height as the pinch point of the weld rollers. Check this by en-
gaging the Drive Foot Pedal and watching the tip of the wedge. It should drive straight to the pinch point
of the weld rollers without touching the top or bottom weld roller first. At the same time, the tilt of the
wedge needs checked. Ensure that the left tip is not placed higher or lower than the right tip. You must
inspect this by getting eye level with the weld rollers. If these are OK, move on to the third alignment
step. If not, locate the Height Lockdown knob and loosen by two turns. This will allow adjustment of the
Height Micrometer Knob. Rotating the Height Micrometer Knob so the numeric value is increasing, will
raise the wedge. Rotating the Height Micrometer Knob so the numeric value is decreasing will lower the
wedge. Adjusting the tilt requires a combination of loosening and tightening the Left Tilt Knob and the
Right Tilt Knob. After the wedge tip height and tilt is aligned, tighten down the Height Lockdown Knob.
Third Alignment Step
The tip of the wedge must be aligned left to right, and centered on the rollers. Check this by engaging the
Drive Foot Pedal and watching to see if the tip is centered on the rollers after it drives forward. If this is
alright, move on to the Fourth Alignment Step. If not, locate the Left/Right Lockdown Knob and loosen
by two turns. This will allow the adjustment of the Left/Right Micrometer Knob. Rotate to decrease the
numeric value on the Left/Right Micrometer Knob will move the wedge to the right. Rotate to increase the
numeric value on the Left/Right Micrometer Knob will move the wedge to the left. After the wedge tip is
aligned left to right with the weld rollers, tighten down the Left/Right Lockdown Knob.
Fourth Alignment Step
The tip of the wedge must be squared to the weld rollers. Check this by engaging Drive Foot Pedal and
looking over the top face of the wedge. See that the wedge squares evenly with the weld rollers. If this is
aligned properly, move on to the Fifth Alignment Step. If not, slightly loosen the Wedge Mounting Bolts,
very slightly rotate the entire heat system in the desired direction and retighten the Wedge Mounting
Bolts. Check the wedge squareness again. Keep repeating until the Wedge is mounted square.
