E71T-11 vs E71T-GS

Hi Folks,

Ran out of my sample roll of .030 FC wire that came with my HH140. Bought a new roll, but it has a little different part number. Could someone explain the difference, please?
Thanks, Russ

Plain and simple GS sucks. Buy a nice roll of Lincoln NR-211 and be happy. I run 5/64 211 almost every day, and keep a roll of .035 211 for my MIG at the house. It is great all around wire, runs smooth, and the slag falls right off of it.

AFAIK, GS means the wire is certified to the standard the manufacturer decides on which can vary a fair bit from place to place. If I'm wrong someone here will chime in and we'll all learn another new thing.

The spec for GS is "as agreed upon between customer and manufacturer", so you never know what you're going to get. I like the Hobart Fabshield 23 fine, but there are other formulations that don't run as well.

If you buy -11, it has to conform to that specification.

I've run the Lincoln, Hobart, ad Radnor -11 flux core wires, and liked the NR-211 best, but I much prefer GMAW.

Thanks Hank, that's what I was trying to say

A E71T-11 must meet certain mechanical properties and must be capable of multipass . As already mentioned but Hankj a GS and G suffix means that properties are "agreed upon " so it can be anything. There is NO mechanical testing required ( tensile , yield, impact, elongation etc )

It does not mean that the electrode is no good , it just means it does not have to to through any testing and meet any criteria.

For example, the new and improved general purpose self shielding flux cored like Lincolns NR212 is "better" mechanically than all T-11s but does not fall into any standard catagory so it must be classified as a E71T-G. This electrode goes through all the mechanical testing and is reported on the CERT


BTW if its GS its for Single pass only. ( G is multi pass ) so be carefull what you use it for

You guys are a great resource. Thanks so much.

Is there a self shielded wire that is geared toward rusty metal outdoors?
Thanks again, Russ
