| MAKING A WELD |
|
|
|
|
|
|
| The serviceability of a product or structure utilizing the |
|
|
|
| |
|
| ity of the builder/user. Many variables beyond the con- |
|
|
| trol of The Lincoln Electric Company affect the results |
|
|
| obtained in using the |
|
|
| ables include, but are not limited to, welding proce- |
|
|
| dure, plate chemistry and temperature, weldment |
|
|
| design, fabrication methods and service requirements. |
|
|
| The available range of the |
|
|
| be suitable for all applications, and the builder/user is |
|
|
| and must be solely responsible for welding settings. |
|
|
|
|
|
|
| • Close the door on the |
|
|
| • Connect the work cable to the metal to be welded. |
|
|
| The work cable must make good electrical contact to |
|
|
| the work. The work must also be grounded as stated |
|
|
| in "Arc Welding Safety Precautions". |
|
|
| • Connect the |
|
|
| source for the polarity and process to be used. |
|
|
| Check that the appropriate power source settings |
|
|
| are made for the procedure to be used. (Refer to the |
|
|
| power source operating and connection instructions.) |
|
|
| • Place the |
|
|
| a safe location to minimize exposure to weld spatter |
|
|
| and to avoid sharp bends in the gun cable. |
|
|
| • Connect the |
|
|
| • Be sure the proper contact tip for the wire size being |
|
|
| used is in the gun. |
|
|
| • Turn on the welding power source, as well as the |
|
|
| shielding gas supply (if used.) |
|
|
| • Cut the electrode within approximately 3/8" (10mm) |
|
|
| of the end of the contact tip for solid wire and within |
|
|
| 3/4" (19mm) of the extension guide for cored wire. |
|
|
| • Position the electrode over the joint. The end of the |
|
|
| electrode should be slightly off the work. |
|
|
| • Lower welding helmet, close the gun trigger and |
|
|
| begin welding. Hold the gun so the contact tip to |
|
|
| work distance gives the correct electrical stickout as |
|
|
| required for the procedure being used. |
|
|
| • To stop welding, release the gun trigger and the pull |
|
|
| the gun away from the work. |
