Just a weld form my newest Miller

[Danny]

Well, I suppose I ve helped sell a few MM 210's over the past couple years with my weld pics on the Hobart site, so lets see if this weld that I produced with my MM 251 helps sell any units over here. This is spray transfer with 98/2, and an .035 E70S-6. To see what the unit is capable of i, ran this at 27 load volts and around 250+ amps

[Teeps]

I HATE YOU!!!! j/k'ing
**** you, off I go to the blood donation center, mm 251 fund taking donations.

Can't do that kind of weld with my 135 amp machine, no way.

Actually it will probably be the miller 210 fund for me though.

Nice lookin' weld, Dan. I hope mine look as good when I get my bottle of 90/10 for my MM251.

Alex,

I wish you were closer; I have a full bottle of 90/10.

Awesome Looking Weld

Dan,

do you have any PICTURES of welds (of similar quality) - that was created by a MM210 using 75/25 ??

Thank You Much,

- Brad

P.S. - that weld is absolutely AMAZING - looks almost "TIG-ian"

Spray Picture

Dan,

Two more questions:

1. Can you explain to me how I can spray with a 210?
2. What is better for all-around use (Spray or short circuit) ??

Thanks

Dan-
Great, smooth weld. Are you part robot?

Brad, you can spray with the 210 however you will be on the upper side of the duty cycle. Wouldn't do it all day. Best for all around use would be the short circuit. It's better for the thinner materials (which is what you would mostly find) and is better for out of position work. Spray is great for flat position and heavier material 3/16, 1/4 and up.

Brad,

C25 is going to limit the MM 210 to short arc and globular transfer, so none of the welds will be as spatter free as the spray arc weld that I ran with the MM 251. However, with the asistance of a little anti-spatter on your base metal, in globular transfer mode you can produce welds that look similar to a spray transfer weld, and will have just as good if not better penetration, because of the arc energy that the C25 will produce at the power level the unit is out putting. Anyway, if you want to try this high energy globular transfer, I recommend using an .030 E70S-6 over an .035 E70S-6, because the amperage that the unit will be outputting to produce this transfer is deeper into the .030 wires spray transfer region, which makes the .030 have a smoother metal transfer. With the .035 wire the machine amperage output is closer to the level were the wire transitions from short arc to spray, so you end up with a pretty harsh globular transfer, that produces large spatter balls. For the most part, the .030 wire produces a fine spatter similar to short arc, mainly because the wire really want to transfer over to a spray arc, but it just does quite make it there. Anyway, here's a picture of a High energy globular transfer weld that i produced with my MM 210 using an .030 E70S-6, and c25 for the shielding gas. BTW, the machine settings were tap#7 and 80 on the wire speed. this translate into about 24 to 25 load volts, and around 200 amps. Also, a lot of the large spatter balls that you will see in the picture come from a weld that I ran to the right of this weld at tap #6 and 80. I didn t spray this part with anti spatter, if i had , there would have be very little if any spatter stuck to the base metal. This 7 and 80 weld is definitely a weld that i would trust my life with on 1/4" steel or even multiple passes on 3/8" or 1/2".

So I guess Dan, that you are quite pleased with your 251... ...That is a great looking bead. That 251 is going to open a whole new world to you with this spray technique.....

Brad,

you need 98% argon/ 2% oxy for you shielding gas, tap #7 for your voltage, and with an .030 E70S-6 around 80 on the wire speed, and you should end up with result similar to this- see attachment. However, like Andy has already stated, your running the machine towards the top end which puts you in the 30% to 40% duty cycle range, which should be fine for small hobbyist level project, but nothing that I try to use on high volume work.


I definitely agree with Andy, for general purpose use short circuit transfer is the way to go. It will allow you to weld thin ga sheet and moderately thicker- 3/16" to 1/4". 1/4" though is were i tend to switch to spray arc if the structure is going to be used for anything critical.


Brad, if your just wanting to stay with one gas mix stick with the C25, and just use the globular transfer settings that i discussed in my previous post on any critcal 1/4" welds. Well that is as long as you can get the joint into the proper position to use the metal transfer. Proper position would be flat for butt joints and flat and horz. for fillets.

Andy

Yeah Andy, I got the eye and arm installed back in the 70's.

[cope]

I can really tell the differecne in my arm stability as I get older. My son-in-law never used a Mig before sesterday. We picked up some 1/8" and 3/16" bar stock and cut it into 3" coupons. After Charlie welded uop the 1/8" on the HH140 I let him try the MM210. He was steady on the 140 but had trouble keeping the weld in the root of the joint, but his first weld with the 210 was beautiful. That's the difference in a young arm I guess.

[2002vlx]

Dan! Those welds are beautiful, and I'm sure they're as strong as they look good. Were those welded with a slight weave pattern, or what? You must have one **** of a steady hand(s). I always get a couple good shakes in there from this ol body during a bead.

Thanks Dan - for your great info. I'll try it and get some pics out. Hopefully with some practice, I'll produce some welds of that grade

Hey guys,

If i'm not mistaken you can run spray transfer with a few different %'s of Ar/CO2 and Ar/oxy. I've run spray transfer with 95AR/5 CO2, and 98/2 AR/CO2, and 90AR/10CO2. I haven't run it in 98ar/2oxy yet but it's something i'd like to try . So i think you can try any of those and still run spray transfer.
