In this video I am unboxing an EDM arc generator by BAXEDM, a few high voltage film capacitors and a pair of insulation rubber gloves. 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.

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

[@jaro6985]

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.

[@spamspammesen5970]

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.

[@toddpiedad651]

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.

[@whatevernamegoeshere3644]

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

[@lazerusmfh]

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 :)

[@TheEsseboy]

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.

[@SidneyCritic]

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.

[@HolgerBarske]

You really don't take no prisoners - hats off for getting sh*t done. Sure I'd like to see you wire EDMimg like crazy, as I have no clue how that works.

[@Arsenic71]

[@VBOMB-wd4mg]

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

[@Spirit532]

You must now use the most radioactive thoriated electrodes and grind them as often as possible, to ensure maximum welding smoothness.

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

[@kreynolds1123]

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.

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.
