248000937 - ESAB Dual Shield 7100 LC .045" Flux-Cored Wire E71T-1C/9C

Premium Gas-Shielded Flux-Cored Wire for Structural Steel

The ESAB Dual Shield 7100 LC is a high-performance gas-shielded flux-cored wire designed for the welding of carbon steels in demanding industrial environments. Meeting AWS A5.20 classifications E71T-1C and E71T-9C, this consumable is engineered to deliver superior mechanical properties, particularly high impact toughness at lower temperatures. The .045-inch diameter offers a versatile balance of deposition rate and puddle control, making it suitable for all-position welding, including vertical-up and overhead applications.

This wire is formulated to operate effectively with either 100% CO2 or a 75% Argon / 25% CO2 shielding gas blend. While the argon mix provides a smoother arc, the use of 100% CO2 is recommended for applications involving high restraint to minimize the risk of solidification cracking. The Dual Shield 7100 LC features a fast-freezing slag system that supports the weld puddle out of position, ensuring consistent bead profiles and excellent fusion.

Ideally suited for heavy fabrication sectors, the Dual Shield 7100 LC is widely used in shipbuilding, barge construction, railcar manufacturing, and bridge construction. Its chemistry is optimized to provide improved operation at lower current levels while maintaining minimal spatter and easily removed slag, enhancing overall productivity and weld quality.
