Stainless Steel
Excessive moisture is indicated by a noisy arc and high spatter, rusty core
wire at the hold end or objectionable coating blisters while welding.
Rebaking of this group of electrodes is not recommended.
Excessive moisture is indicated by a noisy or "digging” arc, high spatter,
tight slag, or undercut. Pre-dry unusually damp electrodes for 30 - 45
minutes at 90°C to 110°C (200°F to 230°F) before final drying to
minimize cracking of the coating.

Storing Stainless Steel Electrodes
Excalibur ® stainless steel covered electrodes should
be handled and stored as if they were low hydrogen
electrodes for welding low steels. They should be
protected from moisture pickup. The consequences
of moisture pickup with Excalibur ® stainless electrodes
do not include cold cracking, as would be the case with
low alloy steels, unless they are used for dissimilar
metal joining. But if Excalibur ® stainless electrodes are

exposed for extended periods a humid environment,
the coating can pick up enough moisture to cause
starting porosity and/or centerline porosity. The
electrodes should be stored in sealed cans, or
stored in an oven at about 120°C (250°F). If they
are exposed to the point that porosity occurs, they
can be restored to like-new condition by baking
one hour at 345 to 425°C (650 to 800°F).
