Big 250 Amp power supply, will it work? This power supply is needed for the next project, which will be "very interesting" and a lot of fun!

Ooooo are we going down the road of Photonicinduction ? Really miss that madcaps videos.

[@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.

[@jessemontano762]

I popped it....!!!

[@MrMersh-ts7jl]

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

[@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).

[@Turbodiesel662]

Transformer welders (AC) are always connected to single phase, or between two phases. That´s the main reason for older AC/DC tig units large fuse requirements. You can not transform three phase primary to one phase secondary. The ability to weld aluminium with AC, outcompetes the drawback of single phase transformers in these types of welders. With inverters and rectifyers, it´s another story.

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.

You are a real life emmet brown . .. 😂 also a legend over here in the UK . Stay safe.

[@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.

[@qwerty70164]

I can't want Mr Carlson. I'm so happy you're back with new projects and regular uploads. Cheers from Poland! You're awesome and I wish you your day to have 48h! 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! 🫡

I love the metal work on old stuff like that. Like on the cord exit. Ooof, yeah, welding gloves better not be damp. I think my Sencore LC meter starts flashing a warning light over 25V. LOL!

[@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

[@MrThomashorst]

You can definitely survice a 240 outlet ... when i was 3 years old, I was connected about 3min until my mother pulled me away from the outlet 😆

[@MrThomashorst]

@@kimtyson9101 Thank god I have no memories left, but it has tought me huge respect for everything related to mains voltage.

[@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)

[@BjornV78]

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. 😇

[@MrCarlsonsLab]

Thanks for sharing your story, I bet that was quite the lesson!

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 :)

[@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!)

[@Morkvonork]

A few years ago you could get used laboratory power supplies for graphite furnace spektrometers from perkin elmer. They were seperate programmable low voltage high current power supplies in 3,5 kilowatt range. Look for HGA 400 for example.

[@Nickbazukaho3nt]

Este señor es un genio 😎👌

[@rilosvideos877]

I had no doubt that this beefy machine would power up easiliy and just work fine! A good old transformer based welding machine is still the best you can use. At least the secondary winding is isolated from mains-ground - so the danger can be handled by just not touching both ends at the same time 🙂

[@nferraro222]

Yeah that "high" reading sounds familiar - I think my old Lincoln tombstone measured 48 volts on it's high setting (no load). I don't recall the low setting.

Thought you might have checked phase to ground with at least the multimeter but preferably a megger just to ensure there were no ground failures and between phases for shorts....Interested to see what you are going to power with this though.
