6. Place the other blade end in the opposite
welding clamp and position it so that the end
evenly butts up against the opposing blade
end, then lock it in place by rotating that lock
lever all the way up, as shown in
Figure 46.
Note: To ensure a good blade weld, it is criti-
cal that the blade ends evenly butt up against
each other.

8. Lower the welding guard down over the blade
ends.
9. Turn the welding station ON.
10. Press and release—DO NOT hold—the weld
button.
Note: A limit switch senses the electrical
resistance between the blade ends. If there
is an adequate amount of welded material,
the limit switch will not allow the weld button
to activate the operation again.
Burning sparks from the blade welding
operation could be thrown in all directions
and cause burns or fire.
When using the blade welder, always keep
the welding guard down and protect your-
self from the flying sparks. Have fire extin-
guishing equipment readily available.
DO NOT weld near flammables.
11. Turn the clamping pressure dial to "0", then
rotate the lock levers down to release the
blade from the welding clamps.
12. Inspect the weld. The welded joint should be
even across the width of the blade with no
gaps (see
Figure 47).

— If the weld is satisfactory, continue to
Step
13.
— If the weld is NOT satisfactory, begin again
at
Step 2.
13. Place the blade in the welding clamps with
the weld centered between the clamps and
re-tighten the lock levers.
Note: The welding operation has left the
blade joint brittle. Annealing will allow the
welded area to cool in a gradual manner, giv-
ing it strength and flexibility.
14. Rapidly press and release—DO NOT hold—
the annealing button two or three times until
the weld zone turns a dull red color.
15. Repeat Step 14 three to four more times,
allowing the weld to cool for about 30 sec-
onds between each repetition.
