S284912-053 - Hobart FabCO 71 .045 Flux-Cored Wire 33lb Vacuum Spool

Hobart FabCO 71 .045" Flux-Cored Wire (33lb Vacuum Spool)

The Hobart FabCO 71 is a premier choice for industrial fabrication, offering a versatile gas-shielded flux-cored wire designed for mild steel and 490 MPa (70 ksi) tensile strength steels. This specific SKU (S284912-053) features a 0.045-inch diameter and comes in a 33-pound Vacuum Packed Spool (VPSP). The vacuum packaging is a critical feature for critical code work, as it hermetically seals the wire to prevent moisture absorption, ensuring the wire maintains its low hydrogen (H4) status from the factory to the job site. This makes it an excellent candidate for applications where hydrogen-induced cracking is a concern.

Engineered for all-position welding, the FabCO 71 excels in vertical-up applications thanks to its fast-freezing slag system. It carries the AWS classification E71T-1C/M and E71T-9C/M H4, indicating its suitability for both single and multi-pass welding with either 100% CO2 or a 75% Argon / 25% CO2 gas mixture. The wire provides excellent mechanical properties, including high impact toughness at low temperatures (typically down to -40°F/-40°C depending on gas), which meets the rigorous demands of structural steel, shipbuilding, and heavy equipment manufacturing.

Operators using the FabCO 71 will appreciate the smooth arc characteristics and low spatter levels, which contribute to higher deposition efficiency and reduced cleanup time. The slag is generally self-peeling or easily removed, further enhancing productivity. Whether used in the shop or for field erection, the Hobart FabCO 71 delivers consistent, high-quality X-ray quality welds. By choosing the vacuum-packed option, you are investing in the integrity of your consumables, ensuring that environmental humidity does not compromise weld quality.
