Safety Information

Welding can be hazardous. Always follow safety precautions to prevent injury or death. This section outlines general safety guidelines. Refer to your welding machine's manual and local safety regulations for comprehensive information.

• Fumes and Gases: Keep your head out of the fumes. Use ventilation or exhaust to remove fumes and gases from the breathing zone and general area.
• Electric Shock: Electric shock can kill. Do not touch live electrical parts. Wear dry insulating gloves and clothing. Insulate yourself from work and ground.
• Arc Rays: Arc rays 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.
• Fire and Explosion: Welding can cause fire or explosion. Keep flammables away from the welding area. Have a fire extinguisher readily available.
• Hot Parts: Hot metal can cause severe burns. Allow welded parts to cool before handling. Use tongs or gloves.
• Noise: Excessive noise can damage hearing. Wear ear protection.

Setup

Proper setup is crucial for effective and safe welding. Ensure all equipment is in good working order before beginning.

1. Prepare the Work Area: Clear the area of any flammable materials. Ensure adequate ventilation.
2. Inspect Equipment: Check your welding machine, cables, electrode holder, and ground clamp for any damage. Replace worn or damaged parts immediately.
3. Select Electrode: Choose the appropriate diameter electrode for your material thickness and welding current. The E318-16 is 1/8 inch in diameter.
4. Connect Cables: Connect the electrode holder cable to the positive (+) terminal and the work clamp cable to the negative (-) terminal for DC Reverse Polarity (DCRP), which is typically recommended for stainless steel electrodes like E318-16.
5. Ground the Workpiece: Securely attach the work clamp to the workpiece or work table to ensure a good electrical connection.
6. Set Welding Current: Refer to the electrode manufacturer's recommendations for amperage settings. For 1/8 inch E318-16, typical current ranges are between 70-110 Amps, depending on position and joint type.
7. Wear Personal Protective Equipment (PPE): Always wear a welding helmet, flame-resistant clothing, welding gloves, and safety shoes.

Operating Instructions

Follow these steps for effective welding with the Westward E318-16 electrode.

1. Prepare the Joint: Ensure the joint is clean, free of oil, grease, paint, and rust. Beveling may be necessary for thicker materials.
2. Strike the Arc: Gently scratch the electrode tip against the workpiece to initiate the arc. Once the arc is established, lift the electrode slightly to maintain the correct arc length (typically equal to the electrode diameter).
3. Maintain Arc Length: Keep a consistent arc length throughout the weld. Too long an arc can lead to porosity and instability; too short can cause sticking.
4. Electrode Angle: Hold the electrode at an angle of approximately 10-20 degrees from vertical in the direction of travel.
5. Travel Speed: Maintain a steady travel speed. Too fast can result in a narrow, convex bead with poor penetration. Too slow can lead to excessive heat input, undercut, or a wide, flat bead.
6. Weave Pattern: For stainless steel, a slight weave or stringer bead technique can be used. Avoid excessive weaving to minimize heat input and prevent carbide precipitation, which can reduce corrosion resistance.
7. Slag Removal: After completing a weld pass, allow the weld to cool slightly, then chip off the slag using a chipping hammer and wire brush. Ensure all slag is removed before depositing subsequent passes.

Storage and Maintenance

Proper storage of electrodes is essential to maintain their quality and performance.

• Storage: Store electrodes in a dry, cool place, ideally in their original sealed packaging. Exposure to moisture can degrade the flux coating, leading to porosity and poor weld quality.
• Re-drying: If electrodes have been exposed to moisture, they may require re-drying. Consult the electrode manufacturer's specifications for re-drying temperatures and times. For E318-16, typical re-drying might be at 250-300°C (482-572°F) for 1-2 hours.
• Handling: Handle electrodes carefully to avoid damaging the flux coating.
• Equipment Maintenance: Regularly inspect and maintain your welding machine, cables, and accessories as per their respective manuals.
