(#11, Figure 7.2) counter clockwise ¼ turn at a time until the desired pressure is
reached. Remember to tighten the lock nut (#14, Figure 7.2) after you have
completed adjustment of the nip pressure to prevent the pressure from backing off
while welding.
Note: When the nip pressure adjustment is set correctly, engaging the nip pressure lever
should take some effort but it should feel like a smooth motion. Again, it is important that
you are getting enough traction to avoid burning out and at the same time providing
enough nip pressure to create a good weld. Keep in mind that the thicker the material
being welded and especially textured material, the greater the pressure should be.

For specific applications of the material you will be welding refer to the Upper
