This table is offered as a general guide to proper storage and oven holding temperatures.
  • Recondition/rebake procedures for electrode coatings exposed to moisture are included.
  • Remove electrodes from containers before placing in ovens.
  • Electrode coatings should not be exposed to the rebaking temperatures without first being reconditioned at a lower temperature. Failure to do so may result in breakdown of electrode coatings. After REBAKING.. lower temperature to HOLDING level until reissued.
  • For flux HOLDING, use type 100FX or 950FX ovens.  For flux HOLDING/REBAKING, type Type 750HT oven.
 Note: Proper redrying temperatures depend upon the electrode type and its condition.  Contact your electrode manufacturer for specific instructions involving critical operations. Phoenix International nor its affiliates do not accept liablility for damage to electrodes and/or welded products resulting from use of this table.  Temperature and times shown are recommended and are not guaranteed to be correct.
