ARC RAYS can burn.
• When using an open arc process, it is necessary to use correct eye, head and body protection.

Stick Welding
Stick welding is probably the most familiar welding process known. A coated ELECTRODE, the weld rod, is clamped into an ELECTRODE HOLDER, an insulated clamping device, which in turn connects to the ELECTRODE CABLE, a heavy wire. The WORK, the metal piece to be welded, is connected to the WORK CABLE, a heavy wire which contains the WORK CLAMP. Quality Lincoln cables use many fine copper wires with a very flexible insulating covering for the electrode and work cables. When properly connected to the OUTPUT STUDS of a high current power source, the electrode melts and bonds the metal being repaired. See “Cable Installation” section for proper cable connection to a

Follow the settings listed in Table B.2 “Welding Application Chart” and the “Electrode Selection Guide” found on the nameplate of the machine.
Learning To Stick Weld
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 information. These variables include, but are not limit- ed to, welding procedure, plate chemistry and tem- perature, weldment design, fabrication methods and service requirements.
No one can learn to weld simply by reading about it. Skill comes only with practice. The following pages will help the inexperienced welder understand weld- ing and develop his skill. For more detailed informa- tion, order a copy of the book “New Lessons in Arc Welding.” (See Book Division section at rear of manual).
The operator’s knowledge of arc welding must go beyond the arc itself. He must know how to control the arc, and this requires a knowledge of the welding circuit and the equipment that provides the electric current used in the arc. The circuit begins where the electrode cable is attached to the welding machine and ends where the work cable cable is attached to the machine. Current flows through the electrode cable to the electrode holder, through the electrode holder to the electrode and across the arc. On the work side of the arc, the current flows through base metal to the work cable and back to the welding machine. The circuit must be complete for the current to flow. To weld, the work clamp must be tightly con- nected to clean base metal. Remove paint, rust,etc. as necessary to get a good connection. Connect the work clamp as close as possible to the area you wish to weld. Avoid allowing the welding circuit to pass through hinges, bearings, electronic components or similar devices that can be damaged.
