Note: To ensure a good blade weld, it is criti- cal that the blade ends evenly butt up against each other.

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.

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.

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.
