MODEL DBW-15
WELD LEVER must be calibrated in the following manner:
1. The weld lever drag spring must be properly shimmed as described above.
2. Loosen but do not remove the two screws that secure the spring, shims and escutcheon.
3. Place a .150" gage between the jaws and bring the weld lever down, so the jaws just touch the
gage.
4. Move the escutcheon (note elongated holes Fig. 5) so the weld lever pointer indicates the
narrowest position (the bottom line on the escutcheon that also corresponds with 1/16" band - note
Fig. 5) and then tighten the two screws.
BLADE ALIGNMENT GUIDES
The blade alignment guides are used to maintain tooth edge alignment of the ends of the band
being welded. Before installing the band guides, check their mounting surfaces on the welder jaws.
These surfaces must be in line within .004", when checked with a straight edge. A file may be used to
bring the surfaces in line. The guides are aligned to protrude below the band clamping surface of the
welder jaws by .025" (Fig. 6). Adjust in the following manner:
1. Loosen the screws holding the "Band Guides" to the jaws.
2. Insert a section of 1" x .035 ga. band into the welder jaws. The band must be out of the jaws (teeth
extend in front of alignment guides by at least 3/16") as shown in Fig. 6.
3. Place a .025" shim on top of the band, but within the jaw clamping area.
4. Clamp the jaws.
5. Adjust the "Band Guides" so they touch the side of the 1" x .035 band and lock in place.
