Well I made an attempt at some 3/32- 7014 welding this weekend, been 5 years since I used it and I can definitely see how easily it is to get slag entrapment. This Miller is so hard to figure out amperage but near as I can tell I ended up with 133.75 amps on AC, way more than my old Century welder use to set that on 100 at the most. Had to have my son help with the math, decimal points always kunfuses me, my son keeps telling me to figure it like money so he says it's like $133.75.

7014 seems to run the best when the rod starts turning red 2" from the stinger, hold the rod in the puddle, a slight drag and weave will help keep slag out of the weld, the rods sure do start easy and if done right dont look half bad. Didn't have that much to weld just a stiffener on top of my stove, the top sagging down in the middle bout 3/8", jack it back up and welded that piece on, that piece might be a little to high not sure yet but might trim some off..

I heard it's only going to be in the 90s this week for you so might be a good time to make sure there's no beavers making a Dam on your land or you could be held responsible for any water damage......................if there is you might have time to smoke your pipe, the Redneck way.

Yeah, I figured out what MOST of my problem wuz with the 7014; the first couple welds were just simple "light it off, let it weld itself", no weave, and ABSOLUTELY no backing up - found out a little weave is OK too, but you just bury the previous slag if you try to back up 'cause you went too fast in one area...

Oh, and you can KEEP the Dialarc (altho you musta got close, welds look fine); and while yer at it, I'd recommend keepin yer KID happy too :laughing: And I'll keep my "complicated" little green machine, where if I want 130 amps I just twist this little knob til the display says "130"

Temps - it hasn't been below 90 for over a week, last 4 days been over 100, up to 104 one day :thumbdown:
So I took 25% of your suggestion, and bought ONE new AC (12000 BTU) - mounted it temporarily on a rollaround rack a buddy GAVE me, puts it just about right to aim at the back of my neck -

- I'm pretty sure I can even get away with leaving the AC on to MIG, it's not a LOT of air and it'll be BEHIND me - we'll see.
Notice the black foot pedal by the fan on the floor, it turns BOTH fans on or off like I mentioned earlier -

It was 101 degrees when I put the AC up, soon as I knew it worked I shut it off and went inside, decided even WITH the A/C blowin' on me it was too dang hot to weld. It's 'sposed to get down to the 80's by Thursday and might even get a sprinkle or two next Monday or Tuesday, here's hoping... Steve

Triple digits, that is on the warm side but least it's a dry heat. It's been down in the 40s here, think I might have hurry up and get my wood stove going. :cold:

Next time you run 3/32-7014 tell me what your amps are on when the rod starts to turn a dull red 2" from the stinger, should be easy when all you have to do is read the numbers.............

I can probably do that, it's supposed to get down to 80 by Thursday; I've got the 3 27"x32" 3/4 plates my "pyramids" will sit on, plenty of room around the edges to run some stringers.

I've also got a DC clamp-on amp meter, as easy as the 7014 runs I'll probably clamp that around the stinger lead just to check accuracy of the greenie's digital readout - shouldn't take more than one hand to run the stinger with that rod... Steve

I haven't got around to playin' with 7014 stick yet, but DID get all but a few minor "touchup" welds done on the last 4 pyramid support blocks for the (hopefully soon to be moved) containers -

- also primed the first two -

They're sitting on 3 of the 180# base plates that'll be under them -

Got tired of tryin' not to catch my "helper" glove (and body parts inside it) on fire - it's not good to have to lean on what you're welding when some of the welds are 16" long @ 200 amps, so I re-purposed a few of the "light duty" tinker toys for a support/guide that is NOT attached to the weldments -

- as you can see, there's height adjustment; and, by re-arranging the 90's I can move it in from the table edge if necessary.

Works really well and just sits in that gray receiver that's clamped to the table - so for grinding, I can just lift the support out of its receiver for easier access.

Next couple days will be more grind and paint; at least it's cooled down to mid 80's, MUCH less painful :thumbsup:... Steve

Finished up grinding/blending all the welds that need to be flat (and a few extras

) -

Some of 'em even look like I almost knew what I wuz doin'

(others, ALMOST as good :laughing

The 4 blocks furthest away will need flipped and other side primed manana, closest two are primed both sides -

'Sposed to be back in the 90's manana, up to 100 Friday; think I'll hide in the big (wood) shop (with the 24" exhaust fan, a 30" pedestal fan and the 36" drum fan) and see if I can hang on to pencil and paper long enough

to sketch out the two "uber-sneaky" (I hope) plasma templates for the container vent fans and inlet louvers... Steve

That's a real slick idea, I can see how that will help with steadiness, back support and fire retardent against those wondering hands in search of something to hang on to without first looking what your hanging on to, I done that many times, weld on one side of something than reach around with my hand and ouch, even with a leather glove on, that heat goes right through and all at once to, then get the glove ASP.
And what's with the red primer, does that color help cool the air down when spraying? The primer I usually see is either grey-ish or brown-ish, not red-ish.

Now your up to navy ship quality there.....:thumbsup: Assuming that's 70s, what gas are you welding with 75/25? that's what I use at home but at the shipyard it's 95/5. Next time I get welding gas I might see if my new dealer can get 95/5, get less spatter with that mixtures and runs a little hotter, 75/25 runs cooler so then the heat has to be turned up.

Now I've been around welding all my life but this is the first I've heard of this, very few good info video's on it but this one shows what's going on fairly good. It's called Spray Powder welding, never seen anything like it, I happen on it while checking out some old cast iron threads on TBN. I was looking for foundry shops that make cast iron parts, haven't found that yet, but take a look at this and see what you know about it, like is this welding process for flat only?
