Re: Dual shield wire? If you working on a contract/quote speed to save labor. To save on cost of wire buy a few hundred pounds at time (about 300 pounds) Welding rod has more clean up over flux core wire.

Considering that 71M is easier for me to run vertical or overhead than any other process, and price-wise its pretty close, I would go with 71M over stick welding any day.

Re: Dual shield wire? I positively crap when they tell me what a spool of wire costs...............then I remember that stick is about the most inefficient transfer method there is. 035 dual shield seems to be more expensive per pound than the 045. and smaller spools exacerbate that.

I think he typed the opposite of he might have wanted to say, perhaps? Just a hunch though. Ive found, its the 035 33lb spools are not as easy to find. Amy aka Welding Queen aka Blue Demon has it, you just have to ask.

Re: Dual shield wire? I know this is off topic, but I'm getting ready to do some welding. Haven't struck an arc in maybe months, or possibly less. But................I'm nervous as Hell. I'm afraid I can't do the thang anymore, or do it as well as I used to. Gettin' old ya know.

Re: Dual shield wire? Originally Posted by Louie1961 Finding 035 gas shielded flux core in anything less than a 33 lb spool can be difficult (but not impossible). What machine do you have? https://www.weldingoutfitter.com/pro...ire-10lb-spool Might not be common in your neck of the woods?????
Re: Dual shield wire? E71T-1 is approved for structural welding and pressure welding requiring low temp. impact strength similar to 7018. E71T-11 is self-shielded, so good for outdoors but as far strength would be more inline with 6013. Not really approved for anything other than general light duty welding.

Re: Dual shield wire? Originally Posted by Oscar Two typical classes of Gas Shielded Flux cored wire (FCAW-G) are: E70T-1 and E71T-1. The "70" is for F/H position, and the "71" is all-position. Minor note, the 7 indicates 70,000 psi tensile. The next digit, 0 is flat or horizontal, 1 is all position.

Re: Dual shield wire? i get "lincoln 71m" in .035 on 10lb spools

Re: Dual shield wire? I agree wi thg h Oscar. I used Dual shield wire with CO2 from 1980 thg o 2004 for spec work . Today in retirement I use just flux core E71T-11 0.030. Great for field work too. Dave Originally Posted by Oscar You cannot use C10 gas as most Gas Shielded flux-cored wires use either C25 or straight CO₂.

They describe which shielding gases are typically used. 1C= 100% CO₂. 1M= C25. 1C/1M= 100% CO₂ or C25. There could be some other wire that use other gas mixtures, but for the most part they use those I listed.
Re: Dual shield wire? It will be C25 I don’t know what I was thinking. I have a new Miller multiprocess 235. How do I subscribe to this thread so that I get e mail updates?

Re: Dual shield wire? E71T-1 is the most common dual-shield used. Lincoln, Hobart, Esab and a host of others carry it.

Dual shield wire? What is my best option for trying some dual shield mig wire? .035 Mostly 1/8”-3/8” material C10 gas multi pass out of position vertical and overhead?? Is there specific dual shield wire or will any flux core wire work? Electrode positive as long as I’m using gas Right??? Thanks
