2. Consignes de sécurité

Welding operations present various hazards. It is imperative to follow all safety precautions to prevent injury or property damage. Always refer to ANSI Z49.1 "Safety in Welding, Cutting, and Allied Processes" and your employer's safety practices.

• Fumées et gaz : Keep your head out of the fumes. Use enough ventilation, exhaust at the arc, or both, to keep fumes and gases from your breathing zone and the general area.
• Choc électrique: Can kill. Do not touch live electrical parts. Wear dry insulating gloves and clothing. Insulate yourself from work and ground.
• Rayons d'arc : Can burn eyes and skin. Wear a welding helmet with a proper shade of filter lens to protect your eyes and face. Wear appropriate protective clothing to protect your skin.
• Incendie et explosion : Welding sparks and hot materials can cause fire or explosion. Keep flammables away from the welding area. Have a fire extinguisher readily available.
• Pièces chaudes : Can cause severe burns. Allow welded materials to cool before handling.

3. Stockage et manutention

Proper storage is crucial to maintain the quality and performance of welding electrodes. These electrodes are supplied in a sealed can to protect them from moisture absorption.

• Store electrodes in their original sealed container in a dry environment.
• Once opened, store electrodes in a heated cabinet or oven at recommended temperatures (typically 250-300°F / 120-150°C) to prevent moisture pickup, especially in humid conditions.
• Avoid exposing electrodes to extreme temperature fluctuations or direct sunlight.
• Handle cans carefully to prevent damage that could compromise the seal.

4. Installation et préparation

Before beginning any welding operation, ensure proper setup of your equipment and workspace.

1. Préparation de l'espace de travail : Clear the welding area of any flammable materials. Ensure adequate ventilation.
2. Équipement de protection individuelle (EPI) : Don appropriate PPE, including a welding helmet, flame-resistant clothing, welding gloves, and safety shoes.
3. Welding Machine: Connect the welding machine according to the manufacturer's instructions. Ensure proper grounding.
4. Sélection des électrodes : Select the appropriate electrode holder and ensure a secure connection.
5. Base Material Preparation: Clean the base metal thoroughly, removing rust, paint, oil, and other contaminants that could affect weld quality.

5. Mode d'emploi

Follow these general guidelines for effective welding with SHIELDARC 70 Plus EO electrodes:

• Paramètre actuel: Refer to the electrode manufacturer's recommendations for amperage settings. Start with the lower end of the range and adjust as needed.
• Longueur de l'arc : Maintain a short arc length, typically equal to the electrode's core wire diameter, for optimal penetration and bead shape.
• Vitesse de voyage: Maintain a consistent travel speed to ensure proper bead width and penetration. Too fast can lead to narrow, convex beads; too slow can cause excessive buildup and overheating.
• Electrode Angle: Hold the electrode at a slight angle (10-15 degrees) in the direction of travel for most applications.
• Tracer un arc : Use a scratching or tapping motion to strike the arc. Once the arc is established, lift the electrode slightly to maintain the desired arc length.
• Élimination des scories : After each pass, allow the weld to cool slightly, then chip away the slag. Ensure all slag is removed before making subsequent passes.

6. Electrode Maintenance

The primary maintenance for these electrodes involves preventing moisture absorption. Once the can is opened, electrodes should be stored in a heated electrode oven to maintain their low hydrogen properties. Electrodes exposed to atmospheric moisture for extended periods may require re-baking according to manufacturer specifications to restore their performance characteristics.
