E71T-11 vs E71T-GS: Multi-Pass vs Single-Pass Flux-Core Wire
Both are self-shielded flux-core wires that work without gas. E71T-11 is multi-pass rated with all-position capability. E71T-GS is single-pass only but works in all positions.
E71T-11: Any structural or multi-pass application. E71T-GS: Light-duty single-pass work: tacking, sheet metal, auto body, hobby welding.
Which One Should You Use?
Pick E71T-11 if:
Any structural or multi-pass application. When weld strength and mechanical properties need to be verifiable. Most serious fabrication work.
Runs on DCEN, 30-225A range. E71T-11 full amperage chart
Pick E71T-GS if:
Light-duty single-pass work: tacking, sheet metal, auto body, hobby welding. Applications where code compliance is not required. Typically less expensive per spool.
Runs on DCEN, 25-150A range. E71T-GS full amperage chart
Key Differences
| Attribute | E71T-11 | E71T-GS |
|---|---|---|
| Pass Rating | Multi-pass rated with AWS-verified mechanical properties | Single-pass only; AWS does not test or guarantee multi-pass properties |

How E71T-11 and E71T-GS Work Together
Many hardware stores only stock E71T-GS because it is cheaper and marketed to hobbyists. For anything beyond hobby work, use E71T-11. The mechanical properties of E71T-GS vary by manufacturer because AWS does not test them.
Common Mistake With E71T-11
Using E71T-GS for multi-pass structural welds. The GS classification explicitly means single-pass only. Multi-pass deposits may have unpredictable properties.

E71T-11 vs E71T-GS: Common Questions
Which is better, E71T-11 or E71T-GS?
It depends on the joint and your equipment. Key differences: Pass Rating: E71T-11 has multi-pass rated with aws-verified mechanical properties, while E71T-GS has single-pass only; aws does not test or guarantee multi-pass properties. Mechanical Properties: E71T-11 has verified tensile, yield, and impact values per aws a5.20, while E71T-GS has properties vary by manufacturer; not standardized beyond single-pass. Polarity: E71T-11 has dcen, self-shielded, while E71T-GS has dcen, self-shielded. Check the spec differences above and pick based on your actual situation.
Can I substitute E71T-11 for E71T-GS?
No. Different rod, different behavior. Penetration differs: E71T-11 is medium, E71T-GS is light.
Can I use both E71T-11 and E71T-GS on the same joint?
Many hardware stores only stock E71T-GS because it is cheaper and marketed to hobbyists. For anything beyond hobby work, use E71T-11. The mechanical properties of E71T-GS vary by manufacturer because AWS does not test them.
