E 308 -17
Covered electrode
for manual metal-arc
welding.
Suffi Cx oating type and usability characteristics
-15 For use with DC+only. Usually basic coating. All positions.
-16 For use with DC+and AC. Rutile coating. All positions.
-17 As for -16, but higher sili ca content in coating gives following:
•More of a spray arc and finer rippled bead surface in H-V fillets. •Slower freezing slag permits
improved handling with a drag technique. •Mitre to slight concave H-V fillets •When making ver-
tical-up fillets the slower freezing slag requires slight weave to produce flat profile.
-25 Same coating and type as for -15 but with a mild steel core wire. Flat and horizontal positions only.
-26 Same coating and type as for -16 but with a mild steel core wire. Flat and horizontal positions only.
