IMPORTANT:
This table is offered as a
guide to proper storage
and oven holding
temperatures for the most
common electrodes in use
today. In addition,
recondition/rebake
procedures for electrode
coatings that have been
exposed to moisture for a
sufficient period of time to
affect the weld quality are
included. Good judgment
and the manufacturer’s
recommendations should
be your guide.

Note: In the HTS
Stainless electrode
groups, and 15 & 16 type
coatings, there can be a
greater difference in the
maximum temperature
requirements for
rebaking than those
shown. This can be
handled by special
request to the particular
manufacturer involved
.
CONTACT YOUR ELECTRODE MANUFACTURER FOR SPECIFIC INFORMATION INVOLVING
CRITICAL OPERATIONS.
Electrode coating should not be exposed to the rebaking temperature without first having been
reconditioned at a lower temperature. Failure to observe this rule will result in breakdown of
electrode coatings.
