*For electrodes that had a short or mild exposure to the atmosphere then re-drying at 300®C for 1 hour will be sufficient. For electrodes that have been exposed to longer or more aggressive conditions or for critical work redrying at 300-350®C for 1-2 hours is recommended. After redrying electrodes should be stored in a hot box.
