GRINDING THE WELDED BAND
Keep hands away from rotating grinding wheel. Because it may be difficult
to see if the wheel is rotating, a pilot light is provided. This light is on
when the grinder motor is running.
After welding, the band must be dressed to remove excess metal or
flash from the weld. Grind the welded area down to the same thickness
as the rest of the band. With the teeth facing out, grind the weld as
shown in the drawing. Handle the band carefully - the weId will be
brittle because it has not been annealed.
G r i n d C a r e f u l l y : do not hit the teeth; or grind deeper than the thick-
ness of the band; or burn or overheat the weld area. Be sure to remove
flash from the back edge of the band. Any flash or "stub" teeth which
project beyond the normal set or height of the other teeth must be ground
o f f . Check the weld thickness by passing it through the correct gage for
the thickness of the band.
Grinding the weld.
SPEClAL NOTE FOR EARLY MODELS Of THE DBW-15
EarIy models of this welder had a different wiring arrangement for the
grinder motor. Thes welders can be recognized easily because they
were equipped with a grinder motor pushbutton and did not have a pilot
light. On these early models only: the grinder motor will not operate
if the weld lever is in its lowest position. Move the lever up before
running the grinder.
