8.Place the other blade end in the opposite welding clamp and position it so that it evenly butts up against the opposing blade end, then lock it in place by rotating the lock lever all the way up, as shown in Figure 29.
Note: For a good blade weld, it is critical that the blade ends evenly butt up against each other without overlap, gaps, or misalignment.

Light generated during the welding process could cause serious eye damage. To reduce your risk, always use eye protection approved for welding when using the blade welder.
Burning sparks may be thrown in all directions while welding. Protect yourself from injury by not welding near flammables and wearing spark-resistant clothing/gloves. Keep fire extinguishing equipment readily available.
9.Press and release the welding button. The blade ends will be welded together.
10.Rotate the lock levers down to release the welding clamps, then rotate the clamping pressure dial to "0".
11.Inspect the weld. The welded joint should be even across the width of the blade with no gaps (see Figure 30).

—If the weld is satisfactory, continue to Step 12.
—If the weld is NOT satisfactory, begin again at Step 2.

Note: The welding operation leaves the blade joint brittle. Annealing allows the material to cool in gradual manner, giving the weld strength and flexibility. When annealing, the blade is heated until it turns a specific color that is determined by the blade material. The annealing process is unsuccessful (blade breaks easily) if the weld is not heated enough or if it is heated too much. For best results, contact the blade manufacturer for the proper annealing color.
