Tested a few different wires the details detected the average user would not notice. For copper coated wires a few companies make wire for different brands. ER70S-6 is a basic wire comes down to copper coating, cast and helix(Memory of wire). Asian wires tend to run a thinner copper coating, slightly dirty with tight cast. Esab tends to flake. Lincoln L-56 and L-59 is expensive due to product approvals. There is more to it than people think
New to the forum, happy to be here.!
I am currently using Blue Demon E71T-1/1M X .035 (bought it back in 2019) on a Lincoln Electric migpak 180 but Iām far from being satisfied. Iām running it electrode negative as I should when using a flux core wire but the welded are aweful. Iām a novice when it comes to welding techniques but I did not have that kind of issue in the welding class I attended last winter.
Iām going to assume your wire is bad. It can absorb moisture. This is pretty common.
Is there any way to āmake it betterā?
Throw it away and get a new spool. Once moisture is in the flux itās done for.
I was given about half of a 30 pound reel, regular mild steel of 0.45 size. Can that kind of wire go bad also ?
Solid wire doesnāt really go bad. It can get rusty though. The flux core stuff is notoriously known for going bad.
Solid core wire if from 2019 may be showing signs of corrosion at that age
Better reference the data sheet. I believe you have the polarity wrong here. Iām seeing Blue Demon E71T-1/1M as a Dual Shield flux core. Meaning it gets a shielding gas and is ran DCEP. That could explain part of your problem. It doesnāt rule out the settings (voltage and wire feed speed), nor the type of gas, flow rate, and contact tip to work distance. Many gas shielded flux core wires are ran in spray transfer, not short circuit. That little machine may not have enough voltage or you might not have the right shielding gas to get into spray transfer. Short circuit transfer is generally 75/25 Argon/CO2. But spray transfer will require a different gas composition.

When I bought that wire on Amazon in 2019 it was not advertised as a dual shielded wire but as a self shielded wire. So what you mentionned dies shed light on my issue!!
Thanks a million to all that answered. So far the welds Iāve made with it seem to be holding okay but as soon as I can get my hands on some shielding gas I may revisit those weldsā¦
