Inweld ER70S-2

[HAWK]

Okay I threw this question out to GTA/SPEC and feel confident he has experience with this material.



Anybody else have any experience with INWELD ER70S-2? I have a 33lb spool on a CV feeder that seems to run decent with 92% argon/8% CO2. However,
the first few pounds were very erratic at best! I tried different guns and liners and even used my favorite 12RC suitcase with an XMT power source. I have tried everything except a different shielding gas I did try a couple of different 330 bottles of the AR8). I am running spray arc, and could toss on a VS feeder, but have not done so yet-should not have to...

I have never seen a wire that runs a great spray arc at 30 volts and 410 inches/minute and then has to be totally readjusted to say 30 volts at 555 IPM to get a good spray. I tried every variable I could think of and it has to be the wire. In all fairness the wire has spooled off fine and burned reasonably well except for the first 4 or 5 pounds. That is a real waste for what this "crap" costs!

I think I will go back to Hobart's QCL bare wire in a .035" diameter with AR8 and crank up the inductance to 35% or so and rock. The INWLED will be a great boat anchor at $2 per pound unless someone can pass along some good experience that can get this "junk" out of its tailspin...

I am using it for MIG and have run a bunch in the past. It has a higher silcon content than ER70S-6. I just cannot get this brand to run well.

I've never run Inweld E70S-2, i normally use Harris Welco E70S-6 .035 and .045, i've used Hobarts wire and a few otheres, but for the price of wire today it's hard to find a good one at a good price. Hawk, your paying $2.00 a lbs? seems a little high to me and i thought the northeast was expensive.

BCarlucci,

1.20 -1.40/lb the going rate on ER70S-6. The 2.00 is because it is an ER70S-2. For some reason it cost more in the southeast. I used to use 44lb spools of National Standard ER70S-6 bare uncoated wire. It has always been my favorite, but GMAW work slowed down and I went with Hobart 10 lb spools.


I don't care for the Harris due to inconsistent quality and too many places of manufacture. However, this INWELD is 10X as bad on quality!!!

I think I will pick up 44lbs of Hobart QCL today in ans ER70S-6. It is suppossed to be better than the National Standard bare wire and is easier to access. Hopefully that will cure the problem. It won't have time to rust since it will be burned by Thursday at the latest.

Hawk,

AWS Spec for Silicone in 70s series wires:

S-6 - .8 to 1.15%
S-2 - .4 to .7%

S2 does have added deoxidizers like zirconium, aluminum and titanium
It is better to run it short arc with Co2, ArCo2, ArCo2O2
not recommended for spray

S2 is not as forgiving as S6

If you are bent on this spray thing, use S6 and get a bottle of SteelMix X from your local Airgas. The added helium really sweetens the spray.

Harris/welco now owned by Lincoln electric most of the 70s-6 is made in italy now have had one bad spool in the last three pallets i got in

Hawk I,ve Run

HAWK,I,ve run inweld but not in a long time.Have always run s6 due to the better forgivness factors.Lately at work they been using RADNOR brand which is new to me but i dont buy the stuff we use at work.I buy tri-mark or harris or ns. Being nosey how thick is the stuff your welding i have never used my mm250x at 30volts also i know the spray arc gives better penetration but it seems like theres alot of hype in this forum about spray arc opposed to short arc is it really that great ?if i was concerned about penatration i would probably just v it out with a grinder or go stick rod.

Will do. I am not bent on the spray thing it just seems like the best way to put together these rebar assemblies. I suppose it's the combo of AR8 and the lower silicon content causing me greif.

With that in mind it is doing pretty darn good. I used about 10 more lbs last evening in the spray mode both tacking rebar and running beads on 3/16 x 1.5 x 1.5 angle iron.

I have a 5 year lease on the AR8 bottle, but will see about a 330 of SteelMix too! I used to use the National Standard bare ER70S-6 in 44lb spools, but have recently decided to try Hobart's answer to that wire in their QCL series. I'll let you know. Thanks for the response.

Hey Hawk,

Ya i've heard of a few problems from Harris about where the wire is made. Currently we only get ours from their Italian Plant, nothing from china, to many problems with the chinese wire. So far the only wire we've gotten in that hasn't had problems is the Harris and Filler metals stuff, i had no idea Harris was bought out by Lincoln thanks for the update though. I have one customer that uses Lincoln Superarc L-56 and i've had to send back 12 spools out of one whole pallet because the wire was rolled wrong. I have a question for you though, why are you using Bare wire? I've seen it but never used it.

Thanks
BCarlucci

Hawk, make sure to get Steelmix X, not just steelmix. It has a little more He.

Radnor steel wires are made by lincoln. I think that its Murex grade, not L56

There are only 2 import wires that i would recommend.

Korea has a wire plant that produces an excellent quality wire, i was very suprised. The wire plant has an exclusive agreement with the local ship yard ( happens to be the biggest in the world)

I spooled up 44lbs of the Hobart QCL and sprayed it with AR8 at 30 volts, 40% inductance, and 375IPM with the.035". It is a truly awesome wire. The rebar went together w/o any sputtering or spatter. I also ran some 6" spray welds connecting mounting plates from 3/8"x 4 flat bar to the 5/8" rebar. Beautiful spary beads. I like the Hobart QCL bare wire. I have never been a fan of CU coated wire and really like the National Standard .035 bare wire. However, I think the Hobart QCL has them beat!

I will look into the steel MIX X as I have several jobs coming up soon if I don;t price myself out of the market due to rising fuel costs. I jumped my rate $10? hour this am and may have to do it again soon!

Thanks for the tip!

I welded with it for a several years in a machine shop and never have like a coated wire since. Of course if you don't go through a lot of wire, it will rust. To me it burns cleaner and with less inductance than any other S6 wire on the market.

[BCarlucci]

Thanks for the info Hawk, most of the guys in my area use the CU coated wire because they don't use enough of it, there are a few guys that use a lot of wire, but trying to get them to switch is like pulling teeth. Maybe i'll get in a spool of the QCL that your using.

Thanks,

Hey Hawk,
From what i have read it seems like you had some problems at the begining of the roll and at the end. I don't think the wire will change on the same roll. I would check the drive roll condition and alignment, and also check to make sure the wire feeds through the liner freely. Have someone watch the drive rolls and the spool speed to make sure your drive rolls are not slipping.
In a spray transfer mode the inductance setting will only have a slight effect on the start of the weld, once thr spray transfer starts the inductance setting has no effect. You can check this by having someone change it while you are welding.
