I'm with hotrex.
I'm not a welder... I suck compared to guys like hotrex. But I've done enough cast iron + flux-core ebay welder to know it works OK for what he wants to do.
My grandfather is really into those old hit & miss engines. One of them he uses to pull a large *** saw-mill. (The blade is like 7/16" thick & about 4' tall). It's driven by a huge belt that runs off one of the flywheels that weighs about 50-75lbs. That is turned on the crankshaft by a key about 3/4-1" thick, slightly taller than that & maybe 5" inches long that fits into a large notch. Needless to say the notch broke flush off the crankshaft decades ago & he just JB welds it back on every time it breaks. It makes it a few uses - so I guess ya can't fault him much.
That ----... You're talking some 1905 (that's the year stamped on it) pig iron. Real low quality, seems *very* hard to weld. I turned my little ebay 130amp fluxcore welder all the way up & went crazy on it. Obviously, the penetration compared to the load & area is a total joke. I'm not going to deny it. (I might add I was using some .35 Lincoln wire. I don't remember if it was NR-202, or NR-211-MP, but whatever it was, it was a general mild-steel wire. It had problems on the old pig-iron. I'm sure something else would have worked better - as co2 & twice the power hah!)

Anywho. 7 true horsepower @ 480rpm.
(7 true horsepower = 92 brake horsepower @ 480 rpm = 1006 lb-ft of torque @ 480rpm!)
Bitch still hasn't moved after little more than a year.

OK so why did I just ramble on? Because:
1) even tho that's got to be the worst application of a cheap *** welder, on the lowest quality iron of all time - that doesn't change the fact that the notch & key is still on there. It has no heat on it - but there is a pretty damn good amount of force on it anytime a load, hits it! A hell of a lot more than his manifold would have.
2) 1000+ lb-ft off a single cylinder, rpm slower than most i4's will idle!? hahahahaha I thought yall would get a kick out of that.. Redline @ 550!


hotrex is right. It sucks & anyone attempting it in a professional job, or a welding class should be shot.
But in the real world, it works fine.

Pretty sure the Smiley tig/combo is DC only, so you won't be doing any aluminum with it either. About the cheapest AC tig you can get new is the Thermal Arc 185tsw.


Also I might be way off, but I thought turbine housing, some manifolds, and the stock ford t3 wastegate housing where cast steel, not cast iron.
I have never had any problems welding cast steel. Cast iron on the other hand almost always seems to just break free almost as soon as the weld cools.
But like I said, I really don't know ----. Just what I thought.

SpankedYA!

Yes I have the Smiley tools tig and its DC only.

ok mr superwelder, you can weld cast with a mig. Is it a perfect penatrated weld? No. Does a mani have to hold up 100,000 lbs at 4000 psi, No. Braze them together? Fuch ya that would work good on something that gets red hot when in heavy use This is the real world not a text book, welcome to the gray area of life HMT4LIFE NI66A

hit and miss engines are awesome.


theres a local guy with a bunch of them and he runs them at the fair. i sit there and just watch

Def.It is almost mesmorizing for some odd reason.

all this talk about cast cannot be welded properly..... whether that's true or not about cast Iron I don't know..... but what exhaust housings and such are made out of I was told is CAST STEEL... that's why i was 'successfully' able to weld a dodge cast down pipe to 2.5 inch charge piping to make an exhaust... If I get the chance I'll pull it off the car and take a pic.
