Description: Description: SELECT 70C-7 is a carbon steel, composite metal cored electrode for gas- shielded arc welding. This electrode is intended for single and multiple pass welding of carbon and certain low alloy steels, where a minimum tensile strength of 70,000 psi is acceptable. Welding positions are primarily limited to horizontal fillets and flat position weldments. Recommended shielding gas is 75–95% argon / balance carbon dioxide or 98% argon/ 2% oxygen. Dew points should be at least -40 degrees F., and flow rates of 40-55 cfh should be maintained. Classification & Approval: E70C-6M per AWS A5.18, SFA 5.18 CWB E491C-6, 6M-H4 (CO2/C5) Characteristics: SELECT 70C-7 is a lower fume, lower spatter version of the SELECT 70C-6 electrode. This product has been formulated to produce substantially less spatter and lower fume generation rates than conventional E70C-6M electrodes. The arc transfer is a soft spray transfer, with a clear weld puddle. Bead geometry is excellent, exhibiting a flat, equal legged profile, with very few slag islands. As with SELECT 70C-6, SELECT 70C-7 offers increased productivity, better fusion on scaled of heavier plate material, and more porosity-free weldments, compared to ER70S-3 and ER70S-6 electrodes. Smaller diameter electrodes can be used in all position welding with either pulse arc or short circuit arc welding process. Applications: The exceptionally smooth arc and low spatter level of the SELECT 70C-7 minimize post weld cleanup, making it ideal for weldments that are to be painted. The low fume levels (40% lower than conventional metal cored electrodes) reduce worker exposure in more difficult-to-ventilate areas. Typical applications would be car & truck frames, structural steels, trailers and earthmoving equipment.
