D. ADDING THE WEIGHT KIT, AND CHECKING THE NOZZLE.
If recommended by the membrane manufacturer, add the 20 pound weight kit. Most membrane
manufacturers require the weights for welding. The amount of weight is a function of the type of
membrane, the type of insulation material and its thickness.
Weight Kit:
To add the weight kit, simply slide the two weights over the preinstalled pins on the platform
over the pressure wheel. A third 10 pound weight (Part# 8622) may be added if required.

B- Welding Nozzle In-line Alignment:
Check the
alignment of the welding nozzle to the compression
wheel as shown in Fig. #2A. The inside edge of the
compression wheel should be in line with the inside
edge of the throat of the welding nozzle as shown
in Figure #2B. Proper alignment of the welding
nozzle to the compression wheel is accomplished
by adjusting the thumb wheel (Illustration #23 on
the part sheet) on the frame of the unit.
