Detailed introduction to 1.2mm  welding wire E71T-1:

FLUX Arc Welding wire (E71T-1):

E71T-1 is an all-position, flux cored welding wire, which is intended for single and multiple pass welding of low-alloy and carbon steel where a minimum 70,000 psi tensile strength is required. It is an excellent general purpose welding wire.  A shielding gas must be used with this wire.

Typical Applications
General-purpose flux cored welding of steel
Structural steel
Farm machinery
Construction equipment
General carbon steel fabrication
