Voltage reg for a keg

[Corn Cracker]

Hoping i can get the reply through this time

The cord with plug is cut off my old welding machine, 3 prong 10awg 240v welder. The cord going to the element from the box is also 10awg 3 wires -ground and 2 hot legs- purchased to hook my house up to a generator in case of power outage years back.

Does the plug have a removable cover on the back of it?
Pics would be nice,but the sites probably to wonky to post it.

it doesn't come apart, molded rubber. The line with the lettering is what I purchased for the gen/ house

The wiring looks right.
I'm fumbuzzled as to why the meter is only showing 122v, It should be 240.
2 thoughts, there's only 120v at the outlet or the meter is wrong.
Do you have a multi-meter to check the voltage?

Agree Shady . That does appear to be a 50a 240v socket . I would also like to see a multimeter read across the two flat pins to confirm as well as between the Ground pin and each flat pin .
It should measure like this . Any other combination including 0v readings indicates a serious problem in the outlet wiring .

It looks to me as if that socket is installed upside down , which makes be wonder if it was actually installed by an electrician or DIY dad .

If there is only 120v across the flat pins , it is possible that one of the Hot wires was connected to the Nuetral bus at the house fuse box or worse , the ground wire and one Hot wire have been cross connected .

It concerns me that a prewired moulded plug intended for a 240v outlet is wired with Black , White and green instead if Black Red and Green .

I really think you should get an electrician to check how that outlet is wired .

I figured it out, it was the breaker, I swapped it and it read 240

So I rebrazed the nut for the element , installed it and put about 7 gl of water in the keg and turned it on

The knob controls it right and the readout follows along with it

This was one of those head scratchers.
Half of the 240v breaker was bad.

[Corn Cracker]

Yeah, not a bad fix, probably a blessing, it won't have the chance to go out mid run.
My neck has been messed up for a week, I can't spend as much time out there as needed right now but it's getting better.

Nice job on your power supply! I hope your neck heals up quickly too.

Doesn’t quite compute … but …

What ever it was , it be fixed now .

1 hot wire and the meter found enough leakage to ground to power itself.
I've seen and measured crazier things using a digital meter.
Some times a simple light bulb or wiggy electical tester works better for trouble shooting.

I guess I should update this thread.

I got it going, reading correctly, i had the dial turned all the way up for about 45 minutes and it was boiling. the lid was on the box and i started adjusting the dial, listening to the keg and element responding immediately to the adjustments, satisfied with all this I turned the knob all the way down and POP went something in the box. I noticed the display was still on and reading as I was quickly turning the breaker off. The little capacitor for the knob blew. The supply company replaced it and I got it installed. I guess the breaker went went bad when I turned it off because it wouldn't send power to the unit today,. I went and got a new 35A breaker and it was back up and running. Thinking it overheated, I kept the lid off and felt the top of the regulator every few minutes and it got warm but never hot at all. I was only running at 4300w instead of the 4,490 it maxes at.

I need help getting power to this, not sure how to go about it. I could unplug the the fan that came with it bit it only has 2 wires and the small plug on the new fan has 3 although, the bigger plug only has 2.

[SW_Shiner]

The three pins will be for connecting to a PWM fan header on a computer motherboard. The to wires on the molex connector(the big extra one) will be just the power wires. this will only give it either on or off function, which is fine for the use. Is it possible to still plug in the small plug to the existing fan header? In a computer, the pins are aligned to allow plugging in either a PWM fan or non PWM. If the header is the same then this should work for you. Otherwise those two extra wires may be the next easiest place to connect.

Thanks, I had to cut and splice the original fans plug in place of the 2 prong plug, I went ahead and joined the small fans wires in the mix so that both fans work, the small is pushing air out of the box and the big new one is on top of the regulator pushing air down onto the heat sink.
