NOTE: The serviceability of a product or structure utilizing this type of information is and must be the sole responsibility of the builder/user. Many variables beyond the control of The Lincoln Electric Company affect the results obtained in applying this type of informa- tion. These variables include, but are not limited to, welding procedure, plate chem- istry and temperature, weldment design, fabrication methods and service require- ments.

STICK WELDING

Stick welding is probably the most familiar welding process known. A coated ELECTRODE, the welding rod, is clamped into an ELECTRODE HOLDER, an insulated clamping device, which is connected to the ELECTRODE CABLE, a heavy wire. The WORK, the piece of metal to be welded, is connected to the WORK CABLE, a heavy wire with a WORK CLAMP on one end. The two cables connect to OUTPUT TERMINALS on the welder, which is a high current power source. See Figure B.3.
