Tru-CoreĀ® FC 71T is a flux cored, gas shielded, all-position electrode intended to weld carbon steel, as well as certain low alloy steels, where a minimum tensile strength of 70,000 psi is required. Tru-CoreĀ® FC 71T is intended for single and multiple pass welding using 100% CO2 or 75-80% Argon/balance CO2 mixtures, for welding in all positions. Major advantages of this electrode include deep penetration, smooth stable arc transfer, low spatter levels and a slag system specially formulated for a high melting point. This provides a very quick-freezing slag.
