Storage welding temperature
Storage temperature of the heated area should be around 150ºC; max. . Ultra Dry III vacuum packed electrodes can be used for approximately 6 hours after opening the packaging without re-drying, the atmospheric conditions must be ≤35°C and ≤90%RH. When electrodes out of the original packaging are exposed for more than 10 hours to an atmosphere with relative humidity. . Exposure to moisture, extreme temperatures, and contaminants can severely degrade their performance and compromise the quality of welds. This moisture absorption leads to cracking. . Opened cans should be stored in a cabinet at 250 to 300°F (120 to 150°C) Low hydrogen stick electrode coatings that have picked up moisture may result in hydrogen induced cracking, particularly in steels with a yield strength of 80,000 psi (550 MPa) and higher.
