7 Material Set-up

The Pro-Wedge is designed to weld a wide range of material types and thickness' from
very thin PE, PP and PVC to very thick materials such as 60-120 Mil (1.5-2.5mm) HDPE.
Non-woven geotextiles can also be welded at very high speeds (up to 32 ft/minute with
stock motor). The Pro-Wedge uses a spring-loaded upper contour roller system and
"floating" wedge design that allows the operator to weld several different thicknesses of
material without resetting the adjustments. However, for best results on all materials, the
following set-up procedure can be used.
Note: before you begin, you will need the following items to set-up a Pro-Wedge hot wedge
welder:
1. Adjust material using the material set up template as seen in Figure 7.1 (P/N 100-160T).
Trace the template on a piece of the material you will be welding, cut it out and write the
word "Top" on your adjustment material at the same location that it appears on the
template. Fold adjustment material so that the word "top" is visible.
2. Set of metric Allen wrenches.
3. 13mm open end wrench.
4. Phillips screw driver.
