Set-Up Procedure
Initial Set-up –Various mil thickness tolerances:
The initial set-up of the Wedge-It is by far the most critical aspect of not only quality welding results, but also wear
and tear on the unit itself.
Adjusting the Wedge-It too tightly can result in excessive wear on drive-train parts, such as gears, chains and
sprockets, etc.
The recommended Set-Up Procedure before heating up the unit is as follows:
From the same mil thickness material as that to be welded, cut 2 pieces app. 4x18” (ca. 100 x 450mm) and 2 small-
er pieces app. ½ x 2” (ca. 13 x 50mm). These 4 pieces of material will be used as „gauges“, for setting the 3 ad-
justments.
Adjustment 1: Wedge Centering
Place the two smaller pieces of material, each folded in half, between the two nip rollers (figure 2). This is to simu-
late 2 layers of material between the rollers. Be sure these pieces do not extend past the Nip Rollers into the ma-
chine. Rotate the Nip Pressure Cam to do first positioning by rotating the Nip Pressure Cam Lever clockwise, until
reaching the mark showing the thickness of your welding sheet.
Move the wedge (figure 4) to the engaged position by rotating the wedge movement handle (figure 2) counterclock-
wise. Adjust the wedge with a 5mm hex wrench by turning the centering adjustment, so that the wedge gets into the
centered between upper and lower nip roller.
Adjustment 2: Wedge forward travel
This adjustment determines how close the wedge is to the nip rollers when it is in the engaged or welding position.
To set clearance, pull out the wedge retract plunger on the wedge movement handle (figure 2), rotate the handle to
a central position between the hold down screws (figure 2), loosen the screws and rotate the handle counter-
clockwise until the retract plunger drops into the lock-in hole.
NOTE: The distance from the upper tip of the wedge to the upper nip roller should be the same distance as between
the two nip rollers. This same clearance should also be maintained between the lower tip of the wedge and the low-
er nip roller.
To lock down the setting, hold down the wedge lock-in plate, pull the retract plunger out, and rotate the handle to
central location between hold-down screws (figure 2). Tighten hold-down screws and move lock-in plunger back to
lock-in hole.
Adjustment 3: Upper and lower contour rollers
Remove the lower contour roller adjustment cover, to expose the adjustment. With a 10mm box end wrench, loosen
the lock-nut. With ad 3mm hex wrench, back off the adjustment until it bottoms out.
With a 10mm wrench, loosen the lock-nut on the upper contour roller adjustment (figure 4). Turn the adjustment
counter-clockwise, raising the upper contour roller assembly out of the way.
With the wedge locked into the engaged position, and the ½ x 2” pieces of material still between the nip rollers, you
are ready to make adjustments.
Insert one of the 4” x 18” pieces of material between the lower contour roller assembly and the wedge. This piece
should extend out of the front of the machine (opposite end from the nip rollers).
Adjust the lower contour rollers up, clockwise, until the wedge begins to move up slightly. Now insert the other 4” x
18” piece of material between upper contour assembly and wedge (figure 4). Adjust the upper contour rollers down,
clockwise, to obtain the desired tolerance.

MUNSCH Kunststoff-Schweißtechnik GmbH Ausgabe 01.2017/Rev.00 8/20
NOTE: This hold be a “snug fit”. To check, hold onto the upper piece of material at the front end of the machine and
move it forward and backward. Check the lower adjustment the same way. Now, make sure the tip of the wedge is
still centered between the nip rollers.
Once the desired tolerance is set, tighten both the upper and lower lock-nuts, being careful not to tighten them too
much.
Replace lower contour roller adjustment cover.
Remove all pieces of material.
NOTE: Although this procedure may appear time consuming at first, with a little practice, the entire set-up should
only take a few minutes.
Suggested set-up for HDPE material
NOTE: Distances #1, 2 & 3 should be the same for the HDPE set-up. For PVC set-up, distance #2 & 3 should be
approximately ½ the distance of #1 and contour roller adjustments should be backed off completely or removed.

9/20 Ausgabe 01.2017/Rev.00 MUNSCH Kunststoff-Schweißtechnik GmbH
Basic welding operation
Heating up the wedge:
Please plug the power cord to the Power supply (110V or 220V, depending on the configuration of Wedge It).
Turn on the switch for temperature (5). Temperature will now show actual temperature (4) and alarm will sound, if
the motor is switched on.
Set the desired temperature and wait until the machine reaches the set point.
Turn on the motor.
If you want, you can now reset the passed distance.
NOTE: Temperature display is in degrees FAHRENHEIT, unless otherwise specified. Recommended temperature
settings can be found on page 13 of this manual.
Whether you are welding small sample pieces, or large sheets, the loading of the material will be the same with the
nip rollers and wedge in the disengaged position and motor switch off.
Position the Wedge-It in the seam, inserting first the bottom sheet of material under the wedge and between the nip
rollers, and then the top sheet of material over the wedge and between the nip rollers. Sheet overlap should be
approximately 5 to 6 inches.
NOTE: Once the bottom sheet of material has been loaded, you may need to manually roll the welder forward and
backward as you are loading the top sheet to prevent a “burn out” at the beginning of the weld.

MUNSCH Kunststoff-Schweißtechnik GmbH Ausgabe 01.2017/Rev.00 10/20
Executing a weld
Please engage the welding pressure by rotating the nip pressure cam lever (9) clockwise to the desired pressure
setting for the thickness of the material that is going to be welded.
The following nip pressure cam positions (15) will help you in achieving the desired pressure:
First position (click)
=
100 mil setting
Second position (click)
=
80 mil setting
Third position (click)
=
60 mil setting
Fourth position (click)
=
40 mil setting
Fifth position (click)
=
20 & 30 mil setting
Now turn on the switch of the motor (2) and rotate the motor speed control (1) to achieve the desired travel speed
(table on page 11). Speed readout (3) should be displaying the current travel speed.
NOTE: The speed at which the Wedge-It must travel to produce a quality weld will vary according to the mil thick-
ness of the material being welded, the temperature of the wedge, the ambient temperature, the temperature of the
welding material, etc. All of these variables must be taken into consideration when choosing a speed setting.
As soon as the Wedge-It begins to travel, rotate the wedge movement handle (12) counter clockwise until the
wedge retract plunger drops into the lock-in plate hole. This should take little or no effort on the part of the operator.
If it does, the wedge has been set too close to the nip rollers and has to be re-adjusted (see page 6).
Removing the Wedge-It at the end of the seam
As soon as the nip rollers have reached the end of the seam, extract the Wedge-It in the following order:
1. Disengage nip rollers pressure
2. Turn the motor switch off
3. Disengage the wedge by pulling out the ring on the wedge retract plunger (10) and by rotating the wedge
movement handle (12) clockwise.
Welding procedure summary
Starting the weld
1. Turn the motor switch on
2. Engage the welding pressure

Preventive maintenance tips
Keeping your Wedge-It clean is the most important factor in prolonging the life of the unit. Simple cleaning practices,
such as brushing off the hot wedge and removing small rocks and dirt or mud from lower contour roller area, should
be performed after each seam is completed.
More involved maintenance practices should be performed on a daily or weekly basis, depending on how much
welding you are doing. Part 1 of this section will explain how to accomplish these tasks.

PART 1
Lubricating gears, sprockets and chains
WARNING: To prevent electronic shock and other bodily harm, make sure unit is unplugged.
a. Remove the drive-side cover to expose main drive mechanism and main wiring terminal (left figure). The
wedge movement handle and adjustment plate will need to be removed for this. Also remove the lower
drive chain cover on opposite side to expose lower drive chain (right figure).
b. Clean all gears, sprockets and chains with brake cleaner or cleaning solvent of your choice and a parts
brush. Wipe with a clean rag, or preferably, blow dry with compressed air. Make sure all components are
clear of dirt and sand, etc. Lightly lubricate all gears, sprockets and chains.
NOTE: MUNSCH Kunststoff-Schweißtechnik GmbH recommends using spray on white lithium grease which is
available at any hardware store or auto parts store.
c. Check chains for proper adjustment and all shoulder bolts, set screws and retaining rings for tightness, in-
cluding wiring terminal screws.

Removing and reinstalling hot wedge assembly
(to replace burnt heating cartridges, thermocouple, etc.)
a. Remove the wedge movement handle, the lock-in plate, and the side cover, to expose the main drive
mechanism and the main wiring terminal (see page 12).
b. Disconnect the thermocouple and the heating cartridge wires from the terminal block.
NOTE: The main terminal block is numbered 1-9, starting from the left side. The thermocouple is
connected to terminal 1 & 2, the heating cartridge wires are connected to terminals 3 to 6.
c. Remove the upper nip sprocket snap ring (30) and slide the sprocket off the shaft.
d. Proceed to the other side of the welder. Please disconnect the nip arm spring (34) from the nip arm and re-
move the nip pivot shaft snap ring (36).
e. Now remove the nip arm (33) from the welder by sliding it off the nip pivot shaft. You can now inxpect and
clean the upper contour roller assembly.
f. Please remove the upper material guide (35) to further expose the hot wedge assembly.
g. Remove the wedge mount set screws (37 & 39) and tap the linear shafts (38 & 40) back through the wedge
mount.
h. After gently guiding the heater and the thermocouple wires through the side frame hole, extract the wedge
assembly by carefully lifting up and out over lower nip roller.
(Now the wedge assembly is ready for cleaning, servicing, replacement, etc.)
i. To replace the wedge assembly, follow steps a-h in reverse order. Make sure the heating cartridge and the
thermocouple wires are tucked neatly between the upper material guide and the side frame. Also, make
sure that there is enough slack in these wires to allow free fore and aft movement of the wedge.
j. Split copper wedge makes changing the heaters simple.

MUNSCH Kunststoff-Schweißtechnik GmbH Ausgabe 01.2017/Rev.00 16/20
Re-Setting timing of rack & pinion wedge movement
Often when removing and reinstalling hot wedge assembly, the relationship of the lock-in plate / wedge
movement handle to the for / aft position of the wedge itself will be off slightly. This can be corrected by pro-
ceeding with the following steps.
A. With lock- in plate hold down screws loose, rotate wedge movement handle counter-clockwise moving
wedge back as close to nip rollers as possible.
B. Insert screwdriver through access slot at the front of the welder between the upper material guide and
the front travel roller. Gently press downwards on the end of the rack gear. This will release mesh be-
tween rack gear and pinion gear.
C. With roller gear still depressed, rotate the wedge movement handle until it is as close to horizontal as
possible and so that the lock-in plunger is in the lock-in hole.
D. Remove the screwdriver and check the wedge movement to make sure the rand and the pinion gears
are meshing properly.
E. Re-set the welding tolerances (see set-up section of this manual).
Temperature alignment
Please follow the mentioned steps carefully!
Not following the instructions may harm the machine!
1. Set the desired temperature
2. Unlock the controller:
a. Keep and pushed until oATP appears.
b. Set it to „0“
