Nice job. I’m about to convert my AC buzz box to DC and had been trying to find some videos specifically about making an inductor like this. I have some 100 amp apc transformers and may modify one and see how it works. Also maybe add a capacitor. Thanks for the video
1000W HID ballast power supply transformer maybe? That's what I've been thinking about using or maybe stacking two 1,000 watt or larger microwave oven transformers. Do you have an LCR meter to measure the inductance of your successful transformer inductor and if so, what is your value?
The length that was used up on the core was probably less than 15 feet. It appears to be 1/0. I already had the wire, it was just a very long electrode holder lead.
i was looking for someone who has tried converting a buzz box. I am in the process of converting an old craftsman with a variable shunt transformer. i will add a 400A FWBR use a 4300 microfarad 600V electrolytic cap with a 150 ohm 2W bleeder. for the inductor filter I'm using two microwave cores (E's only) butted together with twenty turns of three 10 ga insluated stranded wire in parallel with a .045 gap (9 x .005 kraft paper) between the cores to keep the DC current from saturating the core flux (measures 20 microhenries.) Core cross section is ~1.75 x 2.5 . butted the E's to get a longer window(for more turns) and a longer magnetic path length to increase the induction. if needed i will add a second cap to create a Pi filter. suspect that your inductor is saturating and you need to add an air gap in the core to stop core DC saturation so the AC flux can do its thing.
AWESOME VIDEO ! sorry you had to go through so many issues..i'm thinking of doing the same thing to my AIRCO 225 amp welder..question, where did you connect the two leads that you raped on the smoothing choke ? any pictures.. thanks.
I have been running 7018 on my lincoln cracker box since I bought it in 1975 and have had no problem 7018 has been an ac or dc rod since it was invented, you just need to learn how to weld
I feel you. But all ac welders want weld 7018 my friends ac 225 Chicago electric would not hold an arc. I'm a 28 years experienced shipyard production welder.

Great video, what about to put the oscilloscope to see how the signal is, regards

I'm glad this helped! And good luck, that sounds like it should work.
Is that the Montgomery Ward 295? I just picked one up for $20. I want to try.some of the 7018AC rod made for AC welders. 6011 is good so far.

thanks for sharing, great video, but I would like to have more info on your choke; what is the lenght and gauge of the wire you used for it

Good to know....Thank you for posting!
Is your inductor have 6 coils one on top of another or just one set of coils.Nice vidio
It has seven coils underneath the six you see on the outside
tel me in detail for plasma cutting machine also

Electrode holder came out of the choke, ground clamp went in the negative input of the bridge rectifier.
Doesn't that welder already have dc ?
It did not, just ac
Interesting !!
seems like it would have been a lot easier just to buy 7018 AC rod.
Right, I tried that first. Didn't go well.
I tried that almost 30 years ago. The welds looked pretty but something was off in the metallurgy and they would crack.
7018 has always been ac or dc
7018 doesn’t run worth shit on AC
Nice job though.
