dcep
A general purpose electrode for
joining of carbon steel.
Deep-penetrating forceful arc.
Thin slag. Us in all positions,
single and multiple pass, plate
and pipe, galvanized and alloy
steels. Ships, bridges, buildings,
piping, tanks, pressure-vessel
fittings.
E6011
High-cellulose
potassium
F, V,
O, H
ac, dcep
Similar to E6010, but for use
with ac. Dcep gives reduced
penetration.
E6012
High-titania
sodium
F, V,
O, H
ac, dcen
Dense slag that covers the bead,
low-penetrating arc. Use to
bridge joints with poor fitup.
Fillets have smooth convex
face. Runs well at amps higher
