Which brand do you think I should buy Hobart, Lincoln, Harbor Freight, Harris, etc?

What is your favorite self shielding wire? E71T-11 ? E71TG-G

i am planning to weld smaller stuff with solid wire, and use the flux core for more penetration (i will be mostly welding at 120V with my Miller 211AS until i run a 240 circuit).

hobart HB28 E71T-11 also rated for multiple pass
E71G-c is single pass rated wire

I wonder what to use if your local lws doesn't carry hobart.

How would you compare that with the Lincoln NR-211-MP which is also supposed to be a E71T-11?

That Lincoln wire works well.

Bumping up this old thread.

OK I tried the lincoln wire that I bought at home decrapot. I was not pleased with it. It worked Ok for tacking, I couldn't get a real good bead with it. It was outdoor welding and not a fun place to be. At least I got it tacked Ill finish it next week with a stick welder.

It was a shame that this http://www.homedepot.com/h_d1/N-5yc1vZ1xh8/R-100341072/h_d2/ProductDisplay?langId=-1&storeId=10051&catalogId=10053 couldn't.
3/16 cold steel HH140 Maybe if i brought out a torch and heated it could have helped But It was not a fun place to be.

I ran some 2lbs. of lincoln fluxcore last week had no problem. Had to do some welding outside and it worked very well. I ran it on a 210 Millermatic on 3/16 metal.

bobva,

Some guys say the .035 wire is too much for the HH140, and recommend .030 wire.

Other guys say they don't like the NR211 and suggest several Hobart wires. Do a search for NR211 and you will find some don't like it, others do like it.

I have tried Hobart Fabshield 23 (E71T-GS) and Hobart Fabshield 21B (E71T-11) both in .030, on my HH140 and both work well. I like the 21B better.

I use a lot of Hobart fabshield 21b (.045) where it's drafty, when out of the wind like to switch to Excell arc 71, C25 gas (.045).

Bob, you do have the correct polarity for using flux core?

Some of the flux core brands kind of have funny IPM/Amp curves. You sort of have to learn each one and each size individually. Rely heavily on the manufacturers specs for each one. Not as much one for one correlation with the T-GS & T-11 flux core as there is solid wire. I'm one of those that's not a real fan of lincolns 211-mp. Not because it's not good wire tho, because it is. It's just a little finicky is all. I don't like fiddling with settings for a ten minute job so I tend to use something a bit more forgiving.

As to the .035 and a 140 class machine, I think .035 is a bit oversized. Looking at lincolns info you can see that at a low low ipm of 110 ipm you could easily be running at 120 amps. Messing around the other day with some .035 at 225 ipm I was measuring all around 160 amps . At 350 ipm it was running about 180 to 190 amps depending on the voltage tap. From that you can see that .035 can produce well above the limits of a 140 class machine. So why not go down one size in wire and give yourself more room to roam as far as settings go. A .030 can easily reach 140 amps but but give you a broader range of settings due to the ipm/amp ratio.

Bad thing is is that sometimes .030 T-11 is difficult to find in a wide variety of brands and spool sizes and still get a decent price.

I like Hobart Fabshield 21b best.

Is there a difference between Hobart and Hobart Brothers? Here is a link to some Hobart T-11 fluxcore readily available.

I'm not sure just how the family tree goes on this. There are smaller umbrellas under big umbrellas as is typical in corporate schemes. Hobart Brothers has it's Fabsheild 21B and Hobart markets it's E71T-11, both the same spec naturally. Are they manufactured at different locations? I don't know. Is there a qualitive difference? Not that I can tell. Sometimes I think I can tell a difference but that could all be made up in my head too. Someone who welds on a regular basis probably can fill in the blanks on the differences if any.

I know I can never find any Fabshield 21B in .030 but you can in the Hobart generic E71T-11. I rarely want .030 anyway tho.

Thanks for all the great information! From what I can find Hobart & Hobart Brothers are in the same complex however under different ownership. I see that some have said they used Hobart Fabshield 21B (E71T-11) .030 and from what I have found in my research there is NO such product. I spoke with Hobart Brothers and they said they did not make 21B in .030 but in .035 If someone can point me to where to buy it please do so.

So with that information what would be the best .030 flux core wire? I am getting a Miller 211 soon and would like to stock up on some wire first. I have never owned a welder so I am learning as I go...
