MAKING THE WELD
STEP TO ONE SIDE TO AVOID WELDING SPARKS.
(1)
Press (using a smooth and steady motion not too fast or slow) and hold down the weld lever to make the weld. The
lever should be held down until the weld has cooled.
(2)
Release the stationary jaw clamping handle before releasing the weld lever. This will prevent scoring the welder
jaw surface.
(3)
Release the weld lever.
When the lever is released.
the welder mechanism and electrical switches are
automatically recocked.
Special note only for IMPERIAL BI-METAL Saw Band or very narrow carbon band: In order to protect the
weld from accidental breakage, it is recommended that the weld be annealed before it is removed for
grinding, as well as after grinding. Follow the annealing instructions given on a following page.
(4)
Remove the welded saw band. Inspect the weld as described on the next page. If weld is poor, see the Trouble
Shooting Chapter for possible causes.
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 band.
(3)
Preventing shorts or poor electrical contact.
