CLASSIFICATIONS: E70T-1C, E70T-9C per AWS A5.20, ASME SFA 5.20
Select 70 is intended for single and multiple pass welding of carbon
and certain low alloy steels in the flat and horizontal fillet positions.
This electrode is designed for use with carbon dioxide shielding
gas.
APPLICATIONS: Select 70 is ideal for those applications involving
the welding of structural carbon steels, where high deposition rates
and superior penetration characteristics are preferred. An excellent
choice for welding steels such as A36, A285, A515 and A516.
DIAMETERS: 1/16", 5/64", 3/32", 7/64",
1/8"
SHIELDING GAS: 100% CO2, 35-50 cfh
WELDING POSITIONS: Flat and Horizontal
CHARACTERISTICS:
Exceptionally smooth arc transfer over a broad amperage range.
Extremely high welder appeal.
Very low spatter, easily removed slag.
High deoxidation level facilitates welding over mill scale and
rust.
