GRINDING THE WELDED BAND
WARNING
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 weld will be brittle because it has not been annealed.
Grind Carefully: do not hit the teeth; or grind deeper than the thickness 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 off. Check the weld thickness by passing it through the correct gage for the
thickness of the band.
Grinding the weld.
SPECIAL NOTE FOR EARLY MODELS OF THE DBW-15
Early models of this welder had a different wiring arrangement for the grinder
motor. These 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.
