CLASSIFICATIONS: E70T-1C per AWS A5.20, ASME SFA 5.20
Select Super 70 is designed for single and multiple pass welding
of deep groove welds in the flat position, where a minimal volume
of slag coverage is desired. This electrode has a higher deposition
efficiency than conventional E70T-1C electrodes, hence, horizontal
fillets will exhibit a convex bead profile.
APPLICATIONS: Select Super 70 is a good choice for deep groove
weldments such as grooves,
where slag removal between each pass can be a problem. The high
deposition efficiencies of this product make it ideal for welding
construction machinery, earthmoving equipment and other applications
involving heavy plate welding in the flat position.
DIAMETERS: 1/16", 5/64", 3/32"
SHIELDING GAS: 100% CO2, 35-50 cfh
WELDING POSITIONS: Flat and Horizontal
CHARACTERISTICS:
Smooth arc transfer with low spatter.
Thin slag removes easily and cleanly in a deep groove.
High deposition efficiencies in the range of 88-92%.

Notice: The results reported are based upon testing of the product under controlled laboratory conditions in accordance with American Welding Society Standards. Actual use of the product may produce different results due to varying conditions. An example of such conditions would be electrode size, plate chemistry, environment, weldment design, fabrication methods, welding procedure and service requirements. Thus the results are not guarantees for use in the field. The manufacturer disclaims any warranty of merchantability or fitness for any particular purpose with respect to its products.
