“Out-of-Position” Group
All-purpose stick electrodes for general purpose fabrication and maintenance weld-
ing. Capable of x-ray quality welds out-of-position. Particularly good for vertical and
overhead. Deep penetration with maximum admixture. Light slag and flat beads
with distinctive ripples.

Minimum Preheat and Interpass Temperature
(1) Continued
For stick electrode welding only
Based on AWS Specification D1.1
Notes
(1) Welding shall not be done when ambient temp. is lower than 0ºF.
Parts on which metal is being deposited shall be at or above the
specified temperature for a distance equal to the thickness of the part
being welded, but not less than 3”, in all directions from the point of
welding. Preheat and interpass temperature must be sufficient to
prevent cracking. Temperature above the minimum may be
required for highly restrained welds. For ASTM A709 Grade 70W
and ASTM A852 Grade 70, the maximum preheat and interpass tem-
perature shall not exceed 400ºF for thicknesses thru 1-1/2”, and
450ºF for greater thicknesses.
(2) When the base metal temperature is below 32ºF, preheat to at least
70ºF and maintain this minimum temperature during welding.
