2 About The Lincoln Electric Company Lincoln s Wire Lincoln Electric is the world s leading manufacturer of welding equipment and consumables. Our focus is on helping companies make their welding operations more effective, more efficient, more profitable. We are dedicated to two equally important goals: exceptional quality and exceptional service. Our field support team with hundreds of field sales engineers and thousands of knowledgeable and responsive Lincoln distributors in countries all over the world is the largest in the industry. Innovative thinking. A quality, service-first attitude. Fresh approaches to design, manufacturing, and packaging. Worldwide strength. Choose Lincoln., our metal-cored wire product portfolio, is the choice of welders all over the world who demand: quality, consistency, reliability, and performance. You will find that it s well-suited to a wide range of fabrication applications: Automotive Structural Offshore Process Piping Shipbuilding Pressure Vessel Heavy Fabrication General Fabrication We started by asking the world s most demanding welders what they expected in a quality metal-cored wire. Then, we exceeded those expectations... Industry-Leading Consistency Consistency matters to you, and it matters to us. We go to incredible lengths to make sure that our wires are the most consistent metal-cored wires on the market. We check and re-check every pound of incoming raw steel and chemical. Our manufacturing processes are the most meticulously designed, diligently monitored, and technically advanced in the industry. ISO 9001 and ISO certified - manufactured to standards for quality and environmental management systems. 2

3 Exceptional Chemistry In test after test, chemical composition has been shown to be significantly superior to that of other wires on the market. Incredibly tight tolerances. Less adjusting, consistent welds, robust mechanical properties, and increased efficiency. Outstanding Arc Stability More efficient welding translates into a better bottom line. Arc stability makes the difference. Reduce pre-weld surface preparation. Decrease weld time with fast-follow or high deposition and high travel speeds. Improved arc wetting action. Minimize post-weld cleaning with minimal spatter and enhanced silicon island management.

16 Storing Metalshield Wires In general, wires will produce weld deposits which achieve hydrogen levels below 16 milliliters per 100 grams of deposited weld metal. These wires must be properly protected from the atmosphere in order to maintain hydrogen levels as low as possible, to prevent wire rusting, and to prevent porosity during welding. The following storage conditions are recommended for wires in their original, unopened package or container: Maintain a condition of 90 grains of moisture per pound of dry air. Examples of storage conditions that will meet this requirement are the following: Ambient Maximum Temperature Relative Fahrenheit Celsius Humidity % % % % When properly stored, wires may be used up to three years from the date of manufacture in their original, unopened package or container. For best results, wires should be consumed as soon as practicable. Consult your local Lincoln District Sales Office if there is a question as to when a wire was manufactured. Once the wire packaging is opened, wires can be subject to contamination from atmospheric moisture. Care has been taken to select core ingredients that are resistant to moisture pick-up. Condensation of moisture from the atmosphere onto the surface of the wire can occur and can be significant enough to degrade the performance of the wire. The following minimum precautions should be taken to safeguard the wire after opening the original package or container: Use within approximately 1 week; Do not expose to damp or moist conditions; Do not expose to extremes in temperature and/or humidity where surface condensation can occur; Place in sealed poly bags (4 millimeters minimum thickness) or equivalent when not in use. wires will evidence high moisture levels in the form of increased spatter and/or porosity as well as rusty wire and in severe cases, hydrogen induced cracking. Discard any rusty wire. Wires Used for Applications Requiring More Restrictive Hydrogen Controls The AWS specifications for Gas Metal Arc Welding Composite (GMAW-C) wires, AWS 5.18 and AWS 5.28, make available optional supplemental designators for maximum diffusible hydrogen levels of 4, 8, and 16 milliliters of hydrogen per 100 grams of deposited weld metal. These supplemental designators are found with the AWS classification for each wire. For critical applications in which the deposited weld metal hydrogen must be controlled (usually H8 or lower) and/or where shipping and storage conditions are not controlled or known, only hermetically sealed packaging is recommended. wires are available in Pro-Tech, hermetically sealed, vacuum packaging as either a standard product or as a special product. For a special product, consult your local Lincoln District Sales Office. Once the original package or container has been opened, the wire should not be exposed to: Conditions exceeding 80% relative humidity for greater than 16 hours Conditions with less than 80% relative humidity for greater than 24 hours Conditions exceeding 80% relative humidity will decrease the maximum 16 hour exposure period. After exposure, hydrogen levels can be reduced by conditioning the wire. The wire may be conditioned at a temperature of 230ºF ± 25ºF (110ºC ± 4ºC) for a period of 6 to 12 hours, cooled and then stored in sealed poly bags (4 millimeters minimum thickness) or equivalent. Wire on plastic spools should not be heated in excess of 150ºF (66ºC). Discard any rusty wire. 16

Actual results will vary depending on many factors, including, but not limited to, weld procedure, plate chemistry and temperature, weldment design and fabrication methods. Users are cautioned to confirm by qualification testing, or other appropriate means, the suitability of any welding consumable and procedure before use in the intended application.
