CLASSIFICATIONS: E70T-2C per AWS A5.20, ASME SFA 5.20
Select Super 72 is designed to provide clean, porosity-free welds
on heavily oxidized steels and steels with certain glass coatings.
This carbon steel, flux cored electrode is intended for single
pass welding in the flat and horizontal positions. 100% CO2 shielding
gas is recommended.
APPLICATIONS: Select Super 72 is a superb selection for high
speed welds on thin gauge carbon steels, particularly lap and butt
welds. Typical applications include wheel and hub assemblies and
hot water heater weldments, particularly the flue and bottom weldments.
DIAMETERS: 3/32", 1/8"
SHIELDING GAS: 100% CO2, 35-50 cfh
WELDING POSITIONS: Flat and Horizontal
CHARACTERISTICS:
Smooth spray-like arc transfer with low splatter.
Complete coverage with very low slag volume.
Fast travel speeds and good weld bead profiles.

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.
