What is the best kind of dual shield weld wire? Where can I get it?

I am sure one of Hobarts companys makes it, do a search on Hobarts site for the wire. I love running dual shield but i don't have any. I was also looking at the ESAB and Lincoln website's last night at their wire....Bob

Try some Lincoln 71-Elite. I run quite a bit of it in different sizes.

Lincoln e71 elite is some nice stuff, if you do ALOT of out of position welding E71M is just a bit nicer for that, but if you're good the Elite works well too. Note on the Elite that it smokes alot more than the E71M and burns a hair hotter but does seem to leave a much prettier weld. Dave

Another good one is Esab Dual Shield 7100 Ultra:

To me, it's one of the nicest running wires for high deposition use. In the flat position using CO2, you can run .062 at 31 volts (460 amps) with a wire speed of 500 inches per minute.

i have ran 1/16 hobart fabshield 21b with my 302 but felt that it was a little hard on the machine so i'm now running esab dual shield 7100 ultra .045 in all postions. the only problem that i have with this wire is that all my welding is done outside so the wind blows my gas away some times trying to fine some type of tent that would be universal for most of the different jobs that i do. i perfer the esab dual shield 7100 ultra if i can make it work outside on windy days. i have also 4 -- 50 #-- rolls of hobart fabcor 86 that i would like to try and use up in my old hobart wire feed it only takes a 10" roll of wire so i was thinking of drilling a hole in the back of it and feeding the wire into it some how.

Both of these were done with a 3/16 6011 root pass for preheat and finished with esab dual shield 7100 ultra .045 at 250 amps.

DUhhhhh????:confused:

Can someone give me a brief rundown on this "dual shield" wire?? Im at a total loss ??

Dual shield is flux-cored, gas shielded wire. Manufactured or sold by ESAB, Mckay, Hobart, Lincoln. The actual "Dual Shield" name is owned by ESAB. High deposition, deep penetration, all position.

I don't think all dual shield type wire is all position. We have some Lincoln stuff in 3/32" and 5/32" that you could not run in anything but flat or horizontal. I forget the exact model. It's also toxic.l Dave

Bear with me on this folks. Do you run this flux-cored, dual-shield wire just the same as you would regular mig solid wire?:confused: Today is the 1st time I have heard of it.

Yes and no. Depending on the brand and style you can use co2 or c25. You don't want to use too much of a push technique as you WILL get slag inclusion. It runs alot HOTTER than er70S6.....alot hotter.

I'm now running esab dual shield 7100 ultra .045 in all postions. The only problem that I have with this wire is that all my welding is done outside so the wind blows my gas away sometimes

For outside work, you may want to try Esab Coreshield 11. The only drawback IMO is the lower deposition rate with this wire. It runs sweet in all positions.

In the flat position, I run 1/16" Coreshield 11 around 19 volts and 130 inches per minute. It takes only 275 amps to do that, well within the output of the Trailblazer.

At work we use nothing but 1/16" DS 7100 Ultra. But we run 600 amp machines that take full advantage of the higher deposition. With a Trailblazer, 1/16" Coreshield 11 provides a decent deposition rate in a wire you can use in light wind.

No tent required:D

Do they make this stuff in .030 size for my little HH140??......:D

lincon makes the best dual shield fcaw weld wire. the 7100 ultra, im finding, is not efficent. there is such a short range that the wire will weld correctly at ( within + or - 10 amps and + or - .5 volts). moving to lincon a better produced and more efficent weld wire.

ALL flux-cored wires, whether self shielded or gas shielded, are voltage critical. Lincoln, Hobart, Esab, etc. are equally demanding in this regard.

ESO is also critical ... most manufacturers recommend holding the ESO with +/- 1/16" of the stated value.

Travel speed is just as important, as is gun angle. Solid wire with gas shielding is a picnic compared to Innershield or Dual Shield.


...there is such a short range that the wire will weld correctly at... Really? Don't tell the guys where I work. We burn around 6,000 pounds per week of Dual Shield 7100 Ultra, 1/16", with CO2. Sweet running wire.

over the last 4 to 5 months 7100 ultra has been nothing but problems. requiring it to be run within such a tight range. as of now it is out of the shop. i've run it in the past with no problems. my lots of wire covered a two year period, with all not performing as thay should. i don't know if somthing has changeed in the wire, but i will no longer use it.

Exell arc 71 is a nice runing dual shield also.

Not sure which Lincoln wire you're using, we used to run Outershield 71 Elite, also 1/16" with CO2. Our best operator could only run two (50#) rolls per eight hour shift, flat position.

Switching to 7100 Ultra allowed him to burn two (60#) rolls and get almost halfway through a third one, in the same eight hours.

We figured that the 7100 Ultra gave us roughly 25% greater deposition ... or about 25% more production per welder. Pretty significant difference.

I could understand using Outershield if it runs lots easier, or if you aren't using thousands of pounds per week. In our shop, plate thickness runs from 1.5" to 5", and most welds are multipass. We haven't found any wire more productive (and easier to run) than Dual Shield 7100 Ultra.

We use Tripple 7 .045" almost exclusively at my new job. I really like it. Lays in like butter in all positions.

I used to love the ultra 7100, but we started to have problems a year or so ago,I asked my lws about it because I have used this wire for 10 years with no problems,I was told esab was having problems with strikes and the wire was being made somewhere else.I tried some of the triple 7 and it is nice,almost the same as the ultra 7100.
