A carbon steel, flux cored electrode, Select 720A is intended for the single and multiple pass welding of carbon steels in all positions. Carbon dioxide is the recommended shielding gas, however, the use of 75-80% argon/balance carbon dioxide may produce somewhat higher tensile strength with no significant difference in CVN toughness.
Features
Delivers superior CVN toughness at subzero temperatures.
Outstanding welder appeal over a broad range of welding parameters.
Arc transfer is an extremely smooth spray with minimal spatter, even at low current levels.
Provides superb puddle control.
Fast freezing slag facilitates all position welding.
Bead profile is quite flat with only minor convexity.
Applications
Select 720A is an ideal choice for those weldments requiring good CVN toughness and high welder appeal when joining steels such as ASTM A36, A515 Gr 70, A516 Gr 70 and other fine grained steels.
These applications would include shipbuilding, offshore drilling structures, structural welds and general plate fabrication.
Caution
Protect yourself and others read the safety data sheet prior to using this product.
