This welder is a resistance type butt welder capable of welding
1/16 x 0.025" up to 1" x 0.035" Carbon, Dart and Imeprial 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 readjustment 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 0.004" per 4", meas-
ured 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 0.035" 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.
