Hobart's New Wire, Quantum-Arc, 70S-6
 

Hobart is launching its new wire "Quantum-Arc" I have not go tmy hands on any yet. The will be phasing out their old BR-6 wire. I don't think it is spools yet. I think they were replacing the bulk wire first then spools.

Anybody see it in action yet?

Never even heard about it. I have trouble getting HB-28 now. The new Hobart rep here is supposedly a not very liked individual. Most, read that as almost all, stores have yanked all Hobart wire and rods as a result. :( The others don't want to deal with them either, but they will if you force them. I will ask next time I am in. Too bad, I was wanting to give BR-6 a try.

I have run both BR-6 and HB-28 recently, BR-6 in short circuit welding was not impressive, I have since heard out is was meant for spray, this did not come from Hobart but a knowledgeable source. HB-28 is okay but was not my first choice. I am currently running Thermal Arc's 70S-6 wire and will be trialing some of the National Standard wire when it shows up along with the new Hobart Quantum Arc wire. Still looking for a replacement for my old Indura wire.

Don, sorry to hear about your Hobart rep. problems. Our rep. Jason Rausch is great! He is also my Miller Rep. He is very good, just really overworked!

My Esab runs the Br-6 way way better (great in the short-arc) then HB-28 in .035. Every machine runs wire a little different. The Esab 250 runs
both well in the .035 size. It would not even run the Esab
wire they sent with the machine. It was 70S-7 wire.

Good point, all my oberservations above are with my MM 350P.

All that I have run in my 12 RC has been Indura for solid wire and Fabshield 21B. But run fine there.

Sometimes it is such a big deal in how a machine runs wire, it could change how
I think about a machine. Esab had that wire (7 series) on their show/demo
truck running it on a migmaster. You could not even start the arc without
spatter everywhere,and a bead that laid out like crap. I had the rep find some
rusty -6 wire and it worked pretty well. I don't think anybody in their
right mind would of bought one of those machines. It's just not black and
white on wire or machines. I have a hunch the MM-210 would run .035
BR-6 nice.

So what would shade consider a good wire to run in a MM 251, like he had before he sent it packing?

I'm currently running national's NS-6 and it's not bad, but it's not special either. They're against copper coating wires, so the copper is very thin and corrosion in the box was a problem for the first few wraps. It's producing good welds, and arc starts are just as easy as HB-28, it just looks a bit funny because the welds are darker than other wires I've run, and it does feel different to me.

.035 in a 45# spool for 1.10/lb though. Can't complain too much with that.

Not shade, but I would run Lincoln L-56 in mine. :D

I was actually going to get the L-56 when I picked up the NS-6. They wanted nearly $3/lb for the lincoln, and I think they just wanted to move stock on the National Standard. It's supposedly used a lot in big production. It's virtually unheard of by the little guys. I'll be curious to hear what you think of it, Shade.
