2. Informasi Keselamatan

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.

• Asap dan Gas: 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.
• Sengatan listrik: Can kill. Do not touch live electrical parts. Wear dry insulating gloves and clothing. Insulate yourself from work and ground.
• Sinar Busur: 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.
• Kebakaran dan Ledakan: Welding sparks and hot materials can cause fire or explosion. Keep flammables away from the welding area. Have a fire extinguisher readily available.
• Bagian Panas: Can cause severe burns. Allow welded materials to cool before handling.

3. Penyimpanan dan penanganan

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. Pengaturan dan Persiapan

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

1. Persiapan Ruang Kerja: Clear the welding area of any flammable materials. Ensure adequate ventilation.
2. Alat Pelindung Diri (APD): 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. Pemilihan Elektroda: 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. Petunjuk Pengoperasian

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

• Pengaturan Saat Ini: Merujuklah pada rekomendasi produsen elektroda untuk amperage settings. Start with the lower end of the range and adjust as needed.
• Panjang Busur: Maintain a short arc length, typically equal to the electrode's core wire diameter, for optimal penetration and bead shape.
• Kecepatan Perjalanan: 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.
• Striking an 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.
• Penghapusan Terak: 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.
