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

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.
