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.

After rebake, lower temperature to holding level until reissue

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
shown. This can be
handled by special
request to the particular
manufacturer involved.
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.
