This welder is a "resistance type" buttwelder capable of welding 1/16" x. 025" up to 1" x
.035" Carbon, Dart and Imperial band.
WARNING:
All adjustments must be made with the power-off, except where specifically
instructed otherwise.
WELDER JAW ALIGNMENT:
There are three basic adjustments for the alignment of the welder jaws. They are
"Elevation', "Inclination" and "Twist". They are all dependent on one another. Any
adjustment of one may require a re-adjustment of one or both of the others. The welder
jaws shall be aligned to result in a finish weld which is within 4% of the band gage. The
blade alignment guides shall insure that the tooth edge of the band be straight within
.004" per 4", measured 2" on either side of the weld.
The initial line up of the welder jaws is accomplished with a straight edge. The final
adjustment is made so that the weld produced in a 1" x .085" Imperial band will meet the
above specifications.
In order to make the initial adjustment with the straight edge, it is necessary to
remove the lower jaw inserts, the insert bearings, and the blade alignment guides. It is
advisable to remove the transformer straps from the jaws, the jaw upset spring, the weld
lever return spring, and space the jaws approximately 1/8" apart.
