Harris E71T-GS Ten Gauge™ Self-Shielded Flux Cored FCAW Carbon Steel Welding Wire .045 2LB Spool - E71TGSH2

Q: Is the Harris E71T-GS Ten Gauge™ Self-Shielded Flux Cored FCAW Carbon Steel Welding Wire .045 2LB Spool - E71TGSH2 self-shielded or gas-shielded?

The Harris E71T-GS Ten Gauge™ Self-Shielded Flux Cored FCAW Carbon Steel Welding Wire .045 2LB Spool - E71TGSH2 is a self-shielded flux-cored wire (FCAW-S). Self-shielded wire generates its own shielding from the flux core — no external shielding gas is required. This makes it ideal for outdoor, windy conditions where gas shielding would be blown away. FCAW-S is widely used in structural field welding, construction, and heavy equipment repair.

Q: What shielding gas and polarity does the Harris E71T-GS Ten Gauge™ Self-Shielded Flux Cored FCAW Carbon Steel Welding Wire .045 2LB Spool - E71TGSH2 require?

Self-shielded FCAW wire requires no shielding gas — the flux compounds in the core generate shielding gases and a slag blanket during welding. However, FCAW-S typically requires DC− (direct current, electrode negative) polarity — this is opposite to most MIG (solid wire) setups which use DC+. Verify your power source polarity before welding with self-shielded wire.

Q: What is the AWS classification of the Harris E71T-GS Ten Gauge™ Self-Shielded Flux Cored FCAW Carbon Steel Welding Wire .045 2LB Spool - E71TGSH2?

FCAW wire AWS classifications (e.g., E71T-1C for all-position CO2-shielded, E71T-12M for mixed-gas, E71T-11 for self-shielded) encode the wire's shielding type, position, and notch-toughness rating. The classification T number is critical for procedure qualification — substituting a different T classification may require re-qualification of your welding procedure.

Q: What wire diameter is the Harris E71T-GS Ten Gauge™ Self-Shielded Flux Cored FCAW Carbon Steel Welding Wire .045 2LB Spool - E71TGSH2 available in?

The Harris E71T-GS Ten Gauge™ Self-Shielded Flux Cored FCAW Carbon Steel Welding Wire .045 2LB Spool - E71TGSH2 is available in .045 diameter. Common FCAW diameters: .035 in suits lighter section work, .045 in is the most common all-purpose diameter for structural fabrication, .052 in and 1/16 in suit heavy plate and high-deposition applications. Larger diameter wire requires higher amperage and is used in flat/horizontal positions for maximum deposition rate.

Q: How should I store the Harris E71T-GS Ten Gauge™ Self-Shielded Flux Cored FCAW Carbon Steel Welding Wire .045 2LB Spool - E71TGSH2 to prevent moisture pickup?

Flux-cored wire is more moisture-sensitive than solid MIG wire because the hygroscopic flux compounds in the core can absorb atmospheric moisture. Store opened spools in a sealed bag or container with a desiccant packet. Avoid leaving spools on the feeder overnight in humid environments. Wire that has absorbed moisture may produce porosity — if you see porosity that persists despite proper shielding gas flow, wire moisture is a likely cause. Discard wire with visible water damage.
