MAKING THE WELD
WARNING
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
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.
CAUTION
Special note only for IMPERIAL BI-METAL Saw Band or very narrow carbon bond:
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
page 11.
(4) Remove the welded saw band. Inspect the weld as described on
the next page. If weld is poor, see the Troubleshooting 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.
CAUTION
This welder is designed for intermittent use. Repeated welding within a short
period of time may cause the welder to overheat.
