2 1/2 times diameter of rod.
TYPE: STEEL - ARC (low alloy or mild)
Vertical: Make root pass with a straight upward
progression and a short arc Some welders prefer a
V shape motion for root passes. Hesitate at point of

the "V" in the root to assure penetration. Each leg of

the "V" should be about 1/8 in. No whipping should

be done. On subsequent passes, weave across the face
of the root, continuously building up a shelf. The
weave should pause at the sides of the first pass to
clear out trapped slag.
POLARITY: AC or DC Reverse
Overhead: Use only stringer beads. Fillets should
be made with electrode at a 30 degree angle off the
1/8 -100 to 150
Horizontal: Use stringer beads for fillets; direct rod

into joint at a 45 degree angle. On subsequent passes,
use only stringer beads.
Primary: Excellent for joining low-alloy structural
steels such as Cor-Ten, Mayari R, Lukens 45 and 50,
Soft arc, low spatter, good bead contour and wetting
or Yoloy. Use for welding well casings.

Secondary: Joining all mild steels. Buildup prior to
impact resistance at normal and sub-zero
temperatures. Excellent for high-sulfur (free
machining) steels, and cold rolled steels.
PROCEDURES: Hold a short arc and use a slight
