CLASSIFICATIONS: E70T-1C, E70T-9C, E70T-1M, E70T-9M per AWS A5.20, ASME SFA 5.20
APPROVALS: ABS E70T-1; CWB E492T-9-H8
Select 97 is intended for single and multiple pass welding of carbon
steels where a minimum tensile strength of 70,000 psi is required.
This electrode, which utilizes 100 percent carbon
dioxide shielding gas, is specifically designed to reduce fumes.
APPLICATIONS: The lower fume generation rates of Select 97
render it well suited to welding indoors, or where less fume or
smoke is desired. Select 97 can typically be applied in structural
welds, steel fabrication and other general purpose weldments. Typically
generates up to 30% less fume than conventional E70T-1C electrodes.
DIAMETERS: .045", 1/16", 5/64", 3/32"
SHIELDING GAS: 100% CO2, 35-50 cfh
WELDING POSITIONS: Flat and Horizontal
CHARACTERISTICS:
Emits lower fumes than conventional E70T-1C electrodes.
Soft spray-like transfer with low spatter.
Good welding characteristics.
