5. Turn pressure knob to “0” position (pointed
downward). NOTE: There will be some
resistance when turning the knob.
6. Insert one end of the blade in the left clamp
(Figure 19). Position the back edge of the
blade against the back edge of the left
clamp. Then position the end of the blade
midway between the left and right clamps.
Tighten the left clamp.
7. Insert the other end of the blade in the right
clamp. Position the back edge of the blade
against the back of the right clamp. Then
butt the end of the blade against the other
end of the blade (the blade ends need to be
in contact with each other). Tighten the right
clamp.
8. Set the pressure selector switch
(counterclockwise rotation) to the
approximate setting required for the width of
the blade being welded.
Keep hands clear of the weld
area and the clamp jaws during welding.
9. Press and hold the weld button (Figure 19).
When the weld button is pushed, the clamps
move together to apply pressure to the
blade ends. At the same time, sparks will
come from the blade ends as they are being
welded. Do not release weld button until the
blade joint is “red hot.”
10. Release the weld button, and wait 3 or 4
seconds until blade returns to original color.
Unclamp the blade.
11. Rotate the pressure selector switch to “0”.
The welder is designed for
intermittent use. Repeated welding within a
short period of time may cause the welder to
overheat.
12. Remove the blade from the clamps, and
carefully inspect it. The spacing of the teeth
should be uniform and the weld should be
located in the center of the gullet.
Misalignment is easily noted at this time
from the weld appearance. See Figure 20
for examples of incorrect welds.
13. If the weld is imperfect, refer to the trouble-
shooting section on page 28 for possible
remedies to any problems. Make corrections
before annealing.
Annealing
The blade must now be annealed, or cooled at a
controlled rate to prevent it becoming too brittle.
