GRINDING THE WELDED BLADE
▲
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 blade 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 show in the drawing. Handle the blade carefully – the weld is brittle because it has not been
annealed.
Grind Carefully: do not hit the teeth; or grind deeper than the thickness of the blade; or burn or
overheat the weld area. Be sure to remove flash from the back edge of the blade. Any flash or “stub”
teeth that project beyond the normal set or height of the other teeth must be ground off.
CLEAN-UP WELDER JAWS AFTER WELDING
It is important that the welder jaws be kept clean at all times. The jaws and inserts must be wiped or
scraped clean after every weld. Doing this will insure better welds by:
(1) Holding proper alignment.
(2) Preventing flash from becoming embedded in the blade.
(3) Preventing shorts or poor electrical contact.
