[@hugh007]

In my years in the US military we had AC to DC rectifiers that were about the same size as yours. It had terminals on the front to strap it for 12 or 24 volts. It was used to power vehicular radios in stationary settings. They all had tubes, vibrators and dynamotors. At least 100 pounds. Took 2 men to move it. Thanks.

[@KeritechElectronics]

Here comes the Mr PhotonicInduction's Lab! Nice old welder. I'm sure it weighs close to 100kg. Here in Europe you could be 100% certain that a big unit like this would be powered from 3-phase supply.

[@sheep1ewe]

Love You Keri! I actualy have the ignitrons from an old radiator welder which would fit something like this for an old scool DC convertion... ha ha . (I wanted to give them Rons collection ower there but it fell on the shipping cost at the moment).

I worked once for a auto repair shop that was based out of a very large and old dealership in Baltimore Maryland. I think it was built sometime in the '30s or earlier. You could actually see in the basement different construction styles as they add it on throughout pre-war and postwar. At one point they must have been repairing very large trucks because there were at least three or four welders hardwired into the electrical system. Stick welders that were on wheels 3 ft tall and approximately 3 ft in diameter. The cable itself that went to the wall was easily 2 in diameter. Never had bravery to fire one of them up! For all I know there's still hardwired there

The thumbnail with you giving thumbs up on 250 Amps will it work was epic. It said yes it will work, but had the comedic effect of "well, a guess and a prayer will do it." At least for new people who don't know you yet.

[@memejeff]

Such a cool device. Can confirm the device you ran on it was very exciting.

[@nuttyprogrammer]

Aaaah the cliffhanger! 😅 Can't wait...

[@spearmintderg]

Welder here! Of course I immediately had to look and the information plate on the front to see what was going on by the numbers, and saw a duty cycle of 30% @ 250 amps, interesting old machine! For those that don't know, duty cycle indicates the percentage of time that the machine is running where that indicated power is actually available before the machine becomes too hot and has to cool down. So, to put it into context of the span of 10 minutes, you could only weld at 250 amps for 3 minutes out of 10. As you decrease your power draw, the duty cycle increases and at some point becomes 100%, though I do not remember if that graphs as a curve or linear.

The amount of work you do and we can't see it's probably monstrous! You're the definition of passion, knowledge and ability to share those two. Have a amazing day Mr Carlson! 🫡

[@kimtyson9101]

I remember working as a welder/burner at the shipyards in Thunder Bay in the 1970s. The arc welders were massive units each about the size of 4 fridges and the cables had to be "very" long to reach into areas of the 1,000 ft (read 320 meter) lake boats (read grain and iron ore carriers). The entire boat was grounded. So, not standing in puddles (very often) but standing on grounded steel all the time. In February when it snowed and was -30 Fahrenheit you would use a torch to heat up the steel you had to lay/sit on to do the welding. These big welders were smooth like butter. One time my welding gloves got a bit wet while moving some snow aside. I then grabbed a new rod and put it into the holder which of course was live. Not very pleasant but definitely didn't feel life threatening at the time. The amperage setting was around 80 amps but I would guess the voltage on the rod to the grounded ship to be around 80-90 since it did feel pretty close to holding on to wires from a 120VAC house breaker. (which I have grabbed many times and am none the worse for wear.) The real danger is the 240VAC supply. I touched that "once" on the back of a dryer while changing a light bulb and that is incredibly painful and dangerous. Of course Carlson's advice is worth listening to - don't stand in a puddle and touch the "stinger". lol

Mr Carlsons lab you are good at restoring antique radios and alignment of antique radios my friend

[@throttlebottle5906]

on all my welders, I use the 50/30 amp plug and leave the neutral blade out since they don't use the neutral. that way I can plug them into any 3 wire 4 pin 30 or 50 amp receptacle, since the neutral blade it what makes them different. at least anything newer wired that has a 30amp dryer or 50 amp oven receptacle, beyond that temporary breaker and pigtail. (NEMA 14-50R or 14-30R)

[@poormanselectronicsbench2021]

You aren't truly a "Mad Scientist", until your experiments like Tesla, take so much power away from the nearby city Colorado Springs in his case, that you cause it to black out ( denvergazette website has an article with a quote "And in 1899, he sent a lighting bolt more than 100 feet into the air accompanied by a thunderous boom heard up to 20 miles away. The city’s electrical equipment caught fire and Colorado Springs went dark".. This is just "Over-exuberant tinkerer" level compared to that!

[@AllLoudNation365]

Nice one, Paul!

[@TyMoore95503]

What a beast! When I was a kid,my Dad gifted me a 5vdc power supply...after some testing we figured out it current limited at 100 A. I made a right, proper electrolyzer out of it by turning the output voltage down to 2.5V, and i current limited it to 50A...which it more than happily supplied. I had great fun making hydrogen gas to fill balloons...or hydrogen and oxygen for some epic bangs. I once filled up an old, empty 10 gallon aquarium with chlorine gas just for fun. (Chlorine gas is evil: do not mess with it!)

What a beast, reminds me of my welding training at school in 1993. We also had such ancient AC welding machines there. The welding stations were next to each other, separated by a small wall to block the light from the person next to you. One day we were welding with 4mm² electrodes, so the welding machines were set to very high amperage (think around 180A), and the teacher was away for a moment. We started hitting the electrodes of 2 welding machines against each other like the lightsabers in Star Wars. Little did we know, that all the welding machines were connected to each other via the welding tables. The moment the coating of the electrodes was broken off and the electrodes touched each other, there was suddenly a gigantic spark, and sparks of hot metal flew around, both electrodes were almost half gone in a second. Needless to say, we were amazed at what had just happened as 15 year old students. 😇

If it's for arc welding probably you need to modify it. Arc welding power supplies have some serious open circuit voltage at output terminals. And it should have a series inductor needs to be removed. Can't wait to see the huge broadcast tube actually working :)

Now I'm wondering what the heck is Paul going to power up with it? It is a "noisy" AC constant current transformer. For electronics it may need a really big rectifier, a really big one with a heatsink to match! I guess we will find out. I can't wait! Maybe he will finally get a Mad Scientist award from it.
