Now, there is a lot of competition arising in the structural steel industry. On that note, people are shifting from stick welding to flux-cored welding. However, even here, a particular controversy takes place, which is e71t-gs vs. e71t-11.
The thin gauge steel that e71t can weld ranges from 3/16″ to 22″. So, if you are looking for single welding and want to use galvanized material, this fluxed core wire can be a suitable one. In the same way, e71t 11 is an astounding source for the erection of metals and fabrication, like- mild steel. But, remember, the plates that it can weld can’t exceed the measurement of 3/4″.

E71T is a good alternative for thin gauge steel, whereas E71T 11 works well in the erection and fabrication of metals. Similarly, both the products combine a flux compound. And till now, these two flux-cored wires have been serving their best with their utmost great features.
Now you must be speculating what else can be the factors that make them so different. In that regard, I will show you a mere comparison of e71t 11 vs. e71t gs. So, have a gaze below.

Since we are talking about e71t-gs vs. e71t-11, let us give a check on their similarities as well. First, we know both the products are of flux-core welding wires with self shielded welding wire. Also, their outer sheath matches, which have a mixture of alloys and deoxidizers. Thus, you can stay determined to prevent contaminants that are usually inevitable in some welds.
Moreover, e71t-gs and e71t-11 do not require any gas supply. That means there will be no problem if you want to use them for outdoor appliances. But a specific difference that you will get to see is their purpose.
Usually, e71t gs welding wire performs its best in single-pass welding. On the other hand, the e71t 11 welding wire works well in single pass welding and multi-pass welding.
Both of these wires are great for outdoors and generate shielding gas. But still, they combine some of the critical differences.
What does E71T GS mean?
E71t-gs meaning refers to a flux core electrode having carbon steel but no external shielding gas. Again, the e71t-gs flux core has an excellent texture to weld carbon steel which is of thin gauge ranging from 3/16″ to 22″.
Undoubtedly, the e71t-gs specs are going to work superbly on aluminized surfaces and galvanized materials as well. But make sure that you weld the e71t-gs settings with a straight polarity, like DCEN.

WeldingCity 2-pk E71T-GS Flux-Cored MIG Welding Wire
WeldingCity 2 E71T-GS Flux-Cored deserves consideration when it comes to a suitable welding wire. You can use it either with a MIG welder or a flux core welder. As this model is a high-quality welding wire, its designation will help you in no gas operations.
Therefore, you will not need any extra gas for welding protection and to prevent your wire from dirt and contaminants. Now, you get relief from any extra costs that usually bothersome welding wire products.
Moreover, you will not have to carry any external gas tank because the portability of this wire is so good and adjusts anywhere smoothly.
Applications
The WeldingCity 2 E71T-GS Flux-Cored welding wire is best for outdoor application. For example, if you live in a windy location, you will not have to set up any windshields once you have this flux-cored wire.

Cons
- It is often inconsistent during usage
What does E71T 11 mean?
E71T is a flux-cored wire with self-shielding properties which is designed for single and multi-pass welding. It is a type of spray transfer that the welders use commonly for mild/carbon steel that is less than ¾” thick. You can use this wire in all positions, especially in those fields where shielding gases are unnecessary. And on a straight polarity, the best source that you can find is E71T flux-cored wire.
E71T 11 Welding Wire Specifications

UNIMIG E71T-11 is a general-purpose flux-cored wire with self-shielded properties and serves as a tremendous glassless MIG wire. Its designation is done for all positions, e.g., single-pass and multi-pass lap, butt and fillet welds on galvanized or mild steel. You can use this E71T-11 Gasless MIG Wire very quickly as it does not require any shielding gas (gasless operations).
E71T-GS vs E71T-11 Polarity
As I said before, e71t gs offers excellent penetration and produces smooth weld deposits. Therefore, the welders often use it to weld gauge steel of thin combustion in a range of 3/16″ to 22″. So, it will be suitable if you use the e71t gs for single-pass welding.
Whereas the e71t 11 is suitable for both single pass and multi-pass welding. But, the plates that this wire can weld shall not exceed 3/4″. And the same comparison goes for E71T-11 vs. E71T-GS Tensile Strength as per their polarity.

Frequently Asked Questions
Is flux core welding stronger than MIG?
There is nothing complicated to run a flux core in mig. Though you will not need any argon, it will still look a bit messy and stickier than a tig. The best thing will be if you use your flux core in a well-ventilated area as it provides a lot of stick welding. Moreover, the flux core will use less amperage to weld thick metals.
What does JH8 after a Fcaw electrode designation indicate?
You will see multiple diffusible hydrogens in a wire which are vast in amount. These substances are what indicate JH8 after a Fcaw electrode designation.
Why is there no r in a Fcaw electrode designation?
If you notice carefully, you will see that there is no r in a Fcaw electrode designation. That is because the wire conjoining works as an electrode of -14, meaning the operating characteristics. It is an arbitrary number that relates to other flux-cored wires.
How thick can flux core weld?
Generally, a flux core can weld a steep up to a thickness of ¼”, just like a 035″ Innershield NR-211-MP can do. This level of thickness is usually double of a 12 gauge on 115 volts with MIG.
Conclusion on What is the difference between E71T GS and E71T 11?
After evaluating e71t-gs vs. e71t-11, we get to transpire that e7t 11 serves, in most part, better than e71 t gs. We know flux-cored welding wires are way more than traditional solid wires. So, there is no question that you will get expected results from both of these wires.
If you want, you can pick any of them to get the precise preventions from poor-quality welds. But, when it comes to choosing the best, my preference will be e71t-11. So, don’t spill the beans and have a pleasant experience of your most favorite flux-cored welding wire.
