Storage and Handling

• Store in a dry, well-ventilated area at temperatures between 10°C to 30°C (50°F to 86°F).
• Keep the electrodes in their original packaging until ready for use to prevent moisture absorption.
• If the electrodes become damp, recondition them at 250°C (482°F) for 2 hours.
• Handle with clean gloves to prevent contamination by oils or dirt
