| Base material | acero al carbono |
| Type | Flux-cored (FCAW) |
Lincoln Electric Outershield 71 is an E71T-1 flux-cored wire for FCAW welding on carbon steel, classified under AWS A5.20. It is a reference requested by shops and contractors that already have procedures, equipment or internal approvals associated with Lincoln Electric. It differs from ER70S-6 because it is not solid MIG wire: its tubular core generates metallurgical protection and slag, with different cleaning between passes and feeding logic. Compared with ESAB E71T-1, Superon E71T-1 or West Arco Tubular 71T-1, the decision must not be based only on the AWS code; specified brand, packaging, lot, certificates and compatibility with the project WPS also matter.
| Technical data | Reference value |
|---|---|
| Classification | AWS A5.20 E71T-1C / E71T-1M (H8) |
| Process | FCAW-G (gas-shielded flux-cored wire) |
| Shielding gas | 100 % CO₂ (-1C) or Ar+CO₂ 75/25 (-1M) · 17–24 L/min |
| Current | DCEP (electrode positive) |
| AWS A5.20 required tensile | 480–655 MPa (70–95 ksi) |

SoldaForce supplies Lincoln Electric Outershield 71 for industrial projects that require a defined brand and local purchasing support. We dispatch to Bogotá, Medellín, Cali, Barranquilla and all of Colombia. Request a quote via WhatsApp with standard, brand, quantity and delivery city.
It depends on packaging, quantity, availability and dispatch conditions. SoldaForce quotes according to the real project requirement.
Both share AWS A5.20 E71T-1 classification; the practical difference is brand, WPS approval, available packaging and requested traceability.
It is mounted in an FCAW feeder, adjusting rollers, guide, drive tension, polarity and shielding gas when required by the procedure.
Not automatically. ER70S-6 is solid GMAW wire and E71T-1 is FCAW flux-cored wire; the change must be approved by procedure.
For carbon steel compatible with AWS A5.20 E71T-1 classification and with the applicable welding procedure.
It can be quoted with traceability or certificate when lot availability allows it. Indicate this from the request.
