Just for fum I am charging one of the 350 µF 1500 V caps to various voltages only to short-circuit it with a servo motor. Such a high energy discharge could also be used to pump a YAG laser. In the second half of the video I am picking up and repairing an old AC / DC TIG welder by Rehm.
They sent you a full manual and all schematics for a 30 year old product? wow
Žan Pekošak Are they still around? Nice to hear such heroism in corporations.
Not only to exist...they thrive. You can google SIP Šempeter. They make some very impressive farm machinery and its all local from what I understand. I hope to see their factory one day as I am a big fan of farm equipment.
Žan Pekošak Super to hear! I’m a fan of any automation in agriculture.
I Buy This Co. TIG Unit Next Time
Migatronic has done the same for me in the past, for an ancient TIG welder. The trend I’ve found is that the more specialized equipment, the easier it is to get the manuals.
14:20 That's one of the reasons why industrial connectors cost a few bucks each... longevity in use, and replacement!
Love your videos! the acute sens e of humor the all thing is indeed wonderful, but between CNC machines and huge sparks and explosion ..man ! Sparks win hands down all the time .... and they even can bring you much more audience :) Just keep the good work going!
Awesome! Such a huge step for you to get a welder, and one capable of AC/DC too! Soon no project will seem to hard to tackle, just time consuming ;) I advice you train on simpler projects to build up welding speed and muscle memory, takes quite a while to get the feel for it and not have to think excessivly.
I didn't even see that transition to Skillshare coming. So smooth. Random piece of advise, keep the flap disk you use for sharpening the tungsten separate from the one you use for cleaning solder joints. Electrode contamination is no joke.
What a awesome welder and great company. Nice diagnosis of the failures. Cant wait to see more of this.
Nice repair! Welcome to the TIG welding community. I would thoroughly recommend printing yourself an electrode grinder attachment for a Dremel (I use this one - https://www.thingiverse.com/thing:3723973). Consistent tip angles help a lot, especially when learning.
Nice work, Marco. "Welding tips and tricks" has one of the most comprehensive and didactic video libraries on TIG welding I've seen around, in case you are still short of ideas.
someone probably already said this but most of the problems you were having (melting the electrode, the sooty appearance of the weld as well as filler rod oxidization) are most likely caused by too high current and not enough argon flow
Entertaining and informative as always! Looking forward to more great content!!
I miss PhotonicInduction.
I hope Andy comes back to making videos eventually.
We feel you, brother.
He never even properly burned his house down.... There was that time he took out the power for the whole street though..
hes back, just put up a vid about what been happening
You're in luck, he's officially back!
Hello, Sparky here!
Switching on your welder caused your overcurrent protection to trigger because of the inrush current as you said. But there is another solution to your problem: I bet your old device was a 16A type C or even B. This kept you from pulling more than 160A (16Ax10). To get more, a type D would increase this to 320A (16Ax20). In any way, after changing something in your electrical system, you should always measure critical things like the impedance of your circiut. This is to ensure that the new device can accually protect you in an accident. Also, can you measure the inrush current? I would be interested in that.
Cheers

Challenge accepted.
Geert I can’t wait till he makes a mount for that torch on the CNC bed
That H bridge reminds me of my first real life experience of the failure mode of some (most?) high-current semiconductors: They short. At a place I worked we had a huge truck battery charger (48v, maybe 50-60 amps? - the truck weighed about 4 t) where one of the Schottky diodes in the rectifier failed, and it was designed to burn of its lead wire (they where intentionally quite thin solid strand wires). In comes our mechanic, sees the obvious problem (those thin wires are way to thin as one of them melted!), resoldered all of them with heavy gauge wire and turned it on. Quite a spectacular fireworks, and now all the diodes didn't work :P
excellent welding machine, old and reliable, similar to the old esab. on new devices miniature instead of reliability! Congratulations on your purchase!
I welded up quite a bit of 1/4” aluminum last night, best of luck learning. I’m sure you’ve been watching people give tips. Keep everything clean and use clean gloves. Wipe your tig wire down and you’ll be on the right track. If you see a bunch of black garbage around your weld, your argon flow may not be enough. Oh, and that argon bottle is way too small. 😂 if you have AC balance, set it to 30% and when you’re attempting to weld dissimilar sizes of aluminum you will want to use a larger tig wire size or you will likely just keep melting only the wire back :)
With DC the + side is the hot side. If you want more penetration in the metal the GND clamp is +, if you want less distortion, ie less heat, in the metal you go + for the electrode. Most use AC for Alum because it self cleans, but I have heard some people use DC straight on Alum racing engines to reduce the distortion.
oh my this was a great video the destruction comments phrasing i havent laughed that much in a while i thank you good sir. and yes de-ionized water in the tig cooler is the correct fluid the automotive coolant is used when the machine would have been used in areas or shops that would reach freezing temps
My question is how long is the de-ionized water even going to last before becoming contaminated. The anti-freeze should help with corrosion of the copper.
My Fronius AC/DC TIG welder came with pure alcohol to use as cooling fluid. Apparenty they destill it themselves.
Water will be re-inonized rather quickly by being in contact with the metal in the machine.
Is getting shocked by a TIG welder really that dangerous? I'd always thought it was relatively safe, excluding any heart conditions? I've always heard that most accidents happen from poor management of all of the hoses and wires, leading to (sometimes fatal) trips. Second most accidents being fires and burns.
I absolutely love your commentary, very informative and hilarious at the same time
Either make a multi axis CNC or a simple 3 axis cutter/driller. That would be awesome to see!
I don't know how much you plan on welding, but compressed Argon doesn't last very long. You may want to look into refrigerated Argon. Only downside is the dewar will occasionally vent small amounts if you don't consume the gas fast enough.
When washing electronic parts, one can use isopropyl alcohol to displace residual water that makes its way into in tiny spots. Furthermore, the alcohol will dry faster and is less likely to corrode metals.
wow, all is in there now for a DED 3D Metal printer. Just a tiny bit of automatic wirdefeeding to be implemented on your cnc. Very nice seeing someone from lectronics go their way to mechanical engineering ;)
Hints for welding aluminum: Clean the piss out of the material and the filler rod. Use a stainless wire brush on the material (and only use it for alum), and acetone both material and rod. NEVER use brake clean to clean before welding, it will produce a gas that is deadly. Clean part, clean rod = good weld.
"worlds first ergonomic memory tig torch " lmao , this is so accurate
keep doing what you do. You are on the right track. love your videos!!
Interested in knowing whether welding with such an old welder on AC is as obnoxiously loud as the cheap-ish Chinese pulsed TIG I have. All of ToT's videos don't really mention that "feature", so just wondering whether it's due to my welder or just the inherent noise from the interrupted arc.
“Carpet burning photonic induction event” loved it
So I weld for a living and I am going to tell you something that NO ONE told me when learning.
With Alum welding,
1.stab the puddle (the melted bit) your either in or your out. Its a quick in out. No slowly approaching it figuring out where to add rod This is why the rod is balling. Its melting before it has reached the puddle. Like popping a balloon. in out. (maybe not that quick but you get the gist)
2. Don't start moving the puddle till it is reflective. within max 3 seconds. ( I go for 1 sec but that will require you have more experience drive at 40km/h before 150km/h) You have to use a lot of current for this. The very first tip I give people doing Alum with an issue is turn up the amps. Like I have this issue where I... Stop, just turn up the amps..... yeah but I don't think.... Stop. Turn up the amps. Talk to me after that. And I mean WAY high than you think is reasonable with steel. If your used to steel you will feel like ... hold on, that high, your kidding. Nope, that high. It will work.
3. Get the peddle for that thing. It will help a great deal especially with changing geometry of the part. A thick thing will go to a small thing as you weld up to the corner and you will make a dribbling mess. Consider the metal like a heat vessel and if it is small it fills up fast.
4. Dude, bet ya self a bigger bottle. No joke you will use that up in less than an afternoon of not much welding. Get one that stands mid thigh when on the ground.
Have fun, your more likely to burn yourself by picking up something hot than any other risk. (oh your too smart to do that? You have gloves? Ok.... you'll see :-) )
Fascinating, informative, educational, entertaining and above all some of the best wit anywhere to be found!
I had a good laugh at the electrode sharpening method. Love this content!
Can we get a little more wax on the floor here? Your videos are a gold mine. Almost as much fun as experimenting with 50 lbs of fired once .308 military brass, home brew 'close enough' powder mixes and an officially dead Mauser. It's not as lethal as it sounds. I'm using dried tofu for bullets in my pursuit of a formula that predicts when chamber leakage will exceed muzzle energy.
We have made a decision at work. No new equipment should EVER be bought from a company that keep information away from its customers regarding the possibility to repair it if needed in the future. Sales reps get rather annoyed when they are thrown out on that decision... But in the long run, it is a needed way to go for the industry.
The circuit breaker probably blew because you turned the welder on and off and on again. In my welder the input current is lowered by PTC resistors. If I turn it on, off and on again without letting the PTC resistors cool down I always blow the breaker - the new automatic ones.
TIG welding is really nice to watch (well, not with the naked eyes!). Other techniques such as stick welding and MIG look so messy in comparison... I know they all have their own purpose though.
Little diamond wheels on a Dremel work well in evenly disbursing tungsten dust on the bench. Argon inside the bicycle tubing will keep the rowdy electrons in control.
Keep attention with deionized water and copper. It is always said, that you better take tap water or, even better, ad a corrosion inhibitor agent to distilled/deionized water.
No living room is complete without an industrial size tig welding machine. Interior design and dry humour after my own heart.
Love your humor and logical approach . Great job!
Make sure to sharpen that tungsten! The finer the point the finer your arc will be (in theory). It’s also worth it to make sure the type of tungsten you’re using can do all the different processes you’re looking for. AC/DCEP/DCEN. Not all tungsten is created equal. There’s a TON to learn about TIG but I’m sure you can figure it out on your own. I’m excited to see what you do with this.
As far as I know the pointiness of the electrode depends on the task. When I asked my welder friend, he said steel needs really sharp points and alu needs blunt
Marco ! A tig Welder YES !!! I'm glad you caught on with good old TPAI ...The Post-Apocalyptic inventor (he is from Kohln ) ... check his channel if you did not yet have done so ...it's also very very cool in it's own way. Great Video once again ! Just keep up the good work !
You must now use the most radioactive thoriated electrodes and grind them as often as possible, to ensure maximum welding smoothness.
I actually own a REHM AC DC Ultra 230 they are indeed very good machines!
"solder joints that have been cleaned with an angle grinder" -- oof
Not gonna lie, I have ground down solder joints with a rotary tool before.
LMFAO
Was the first of Marco's jokes that made me smile.
LFMO also!
Just to be cautious grinding thoriated tungsten gives off radioactive particles when grinding ,,do not breath it in and make sure you do it in a well ventilated area..even so letting this get into the environment is something to be considerate a negative. some sort of collection fan filter should be used to at least catch the fine particles for proper disposal..
I'm developing a cheap (under 100 USD) Arduino based EDM generator (well, I have used it several times, just getting it ready to show) that can be attached to any 3D printer. The idea is to get it easy to make so it can grow and people can improve it as open source project. Hopefully, the next LinuxCNC distribution will be able to back feed so I can attach it to my mill too.
So did you ever make the video and boxing all of the laser parts? Seems like such a nice package and very generous parts and I assumed there would be a video about it.
I don't comment much but I watch all your videos- always educational , entertaining and inspiring- awesome! Merry Christmas -congratulations on a super channel

Really good. Glad to se your wearing steel toe caps socks! Thanks for sharing. I think the main reason for all the caps is to block the HF starting geting back into the power electronics. I have repaired a few welder and a Plasma cutter on my own channel. Regards Chris
