Adjustment #3: Upper and Lower Contour Rollers
Before beginning Adjustment #3 make sure the Wedge is locked into the Engaged/Welding
position and the two folded 1/2" X 6" material pieces are still locked between the Nip
Rollers. This Adjustment may seem time consuming at first but with practice and
experience the entire set-up process takes only a few minutes.
a. Insert one of the 4" X 18" material pieces between the Lower Contour Roller Assembly
and the Wedge (see Diagram 3). This piece should extend out of the front of the welder
(opposite end from the Nip Rollers).
upwards by turning the Adjustment Screw (3) (see Figure 1) clockwise until the Wedge
begins to move up slightly.
b. Insert the remaining 4" X 18" material piece between the Upper Contour Roller
Assembly and the Wedge (see Diagram 4). This piece should extend out of the front of
the welder (opposite end from the Nip Rollers). Adjust the Upper Contour Roller
Assembly downwards by turning the Upper Contour Roller Adjustment Knob (2) (see
Figure 2) clockwise until the desired tension is achieved.
c. Check for proper adjustment by grabbing hold of the upper material piece protruding
from the front of the welder and move it forward and backward. The fit should be snug
causing a drag on the material. Check the lower material piece in the same way. Further
adjust the Upper and/or Lower Contour Roller Assemblies as necessary to achieve the
desired snug fit. When finished the drag (friction) on the upper and lower material pieces
should feel the same. During all adjustments make sure the Wedge remains centered
between the Nip Rollers.
d. Once the desired tension is achieved tighten both Upper and Lower Contour Roller
Assembly Locknuts being careful not to over-tighten, replace the Lower Contour Roller
Adjustment Cover remove all material pieces from welder.
