9.Rotate the lock levers down to release the welding clamps, then rotate the clamping pressure dial to "0".
10.Inspect the weld. The welded joint should be even across the width of the blade with no gaps (see Figure 38).

—If the weld is satisfactory, continue to Step 11.
—If the weld is NOT satisfactory, begin again at Step 2.
11.Set the clamping pressure dial to 4 or greater to bring the welding clamps close together.
12.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 material to cool in gradual manner, giving the weld strength and flexibility.
13.Rapidly press and release—DO NOT hold— the annealing button two or three times until the weld zone turns dull red.
14.Repeat Step 13 three to four more times, allowing the weld to cool for about 30 sec- onds between each repetition.

15.Allow the blade to cool, then re-inspect the weld.
16.Grind away the weld flash flat on the top and bottom of the joint so that the blade will run smoothly on the wheels.
Note: Make sure not to grind the teeth or blade body, or overheat the blade during
17.Re-clamp the blade in the welding clamps with the joint centered, then repeat Step 13 twice more.
18.Test the strength and flexibility of the weld by bending the blade in an arc similar to that of the bandsaw wheels. The blade should bend smoothly without any angles (see Figure 39).
