How to Make a Plasma Cutting Machine From Scrap

[@francoisguyot9770]

I just discovered your channel by chance and I must say, I like it. Actually I like the fact that you try using whatever you have around to practically make useful tools and stuffs. That's the Mc Gyver spirit that I've been trying to acquire for years... But I'm still struggling because it's so hard to polish my knowledge in all fields without being naturally smart, practicing often enough and while your brain is leaking away.So keep it up, keep inspiring us, keep it simple with schematics on the fly. We definitely need more Mc Gyvers to keep re-inventing the wheels. Because we've taken it for granted, because buying stuffs, new tools cuts through the chase, but is not as rewarding from a personal DIY perspective. So, thanks!

[@UnitWeld]

Rulof my friend I really appreciate showing this type of technological content that is very little found on KZbin. The young folk should learn more about practical cases and how the backbone of industry works and not only do small projects with IoT or other modern stuff. Coming from a Power Electronic Engineer which is Specialized in Welding Machine design you deserve a big Like.

The overlays and explanations were very well done. Kudos to your editing skills!

FULL BRIDGE RECTIFIER

[@jonathanseagraves8140]

One bit of information that may be useful to any of you who are wanting to recreate this project: You can DIY everything but the handpiece. The reason (other than it would be unnecessarily difficult to build) is because the electrode has a little nugget of hafnium oxide imbedded (which is a consumable btw). It's purpose is to more freely donate electrons (or whatever the verbiage was). The better explanation is it makes it possible to ionize dry compressed air into a plasma, otherwise you would have to run Argon (or some other mix of easily ionizable gas) through your rig and when it's not necessary, why bother with all that hassle and expense. I spent a lot of time fucking around before I realized this.

[@jackrichards1863]

True, But see how intelligent you became for all that FAQing around? I found a couple $100 for a cheapie. Still you educate me (all your readers)on what is in there.(has a warrantee too btw) It interests me to consider making my plasma more powerful...

[@jonathanseagraves8140]

That may have been the nicest thing anyone has ever said on KZbin. Thanks @@jackrichards1863

[@fredymredy]

I want to recreate this and the tig welder, but im going to need some advice. Is there a way that we can stay in contact?

[@jonathanseagraves8140]

@@fredymredy Sure, I'm not on KZbin as much as I WAS, but I'll answer any question that you have. The only thing that I have actually done in reality is make a HF start circuit, which worked pretty well. I ended up using a home made ZVS flyback circuit where the output was attached across a home made HV capacitor (made of transparency film and aluminum foil rolled up and then wrapped with plumbers tape and filled with hot glue.) and a spark gap. I had that discharge through a transformer core with the secondary as the tig supply. (to give you the isolated HV starting spark at the electrode) I think this is pretty much what the guy in the video did. But you know, its always easer to be able to ask someone direct questions... this shit is hard to figure out on your own.

[@pedroaltinier.8441]

Hay países donde no se tiene acceso ,recuerdo por el 2007 arme una tig con hf que encontré de un aficionado de EEUU ,estoy en argentina y eran carísimas.y no las tenía cualquiera

[@bartramirwin]

yo man you rock i totally dig the manner in which you explain and deal with all the processes necessary to complete projects

[@MidnightOilsRestoration]

Information like this is very much needed thank you! It’s unfortunate that so much information has either been kept trade secret or made so complicated that the average person is deterred from even attempting it! This forces people to spend money instead of developing their skills to do things cheaply!

[@TheSomar1991]

This is a full fledged project nice job, the time and effort put into this is crazy. Great video

[@theyoutubeguy1545]

Wow, I'm so happy to have found you. This is exactly what I've been searching for. I'm no electrician and certainly not an engineer but I am a builder/tinkerer who's surrounded by a sea of discarded electronics just floating around for the taking. And I've long suspected with the right knowledge and direction one can build just about anything the big companies want to charge an arm and a leg for. All while our Earth is being poisoned by this disposable life style. But unfortunately there are few creators putting out the kind of content that will help demystify these kind of projects. Thank you for sharing and I can't wait to see what else you've crafted

[@NameLast-wm5je]

Many places, including here, it is a crime with harsh punishment for taking electronics from the garbage :( Mad mad world

[@bradrogers4281]

[@nathan584]

This is one of those things I would strongly recommend not building diy but you did and it works so I'm impressed none the less. But holy moly I cannot stress enough how dangerous this type of thing is

[@elliottdiedrich3068]

Going outside could be dangerous too if you don't pay attention. Just don't do nuthin stupid!

[@Hellsong89]

@@elliottdiedrich3068 Yes, but one should very least understand how the damn thing works and dangers that come with it, like how you can easily kill your self with a tig torch if you fuck up even with just the usage of it. I agree most things are pampered too much when risks are very little but high voltage and combining them with current is one of those things you dont want to fuck around and find out. This comes from guy who knows about electricity enough not to get killed (so far), has gotten shocked several times due mistakes my own or others and DIY guy with several bit sketchy jerry rig builds.

Rulof, this is a great video and I truly enjoyed not only the project but also your personality and outside-the-box thinking. I recycle components out of discarded electronics as well and use them in my projects and builds, and I can see now why my friends want me to start filming content - after watching this I'm inspired to share my work as well. Keep on with the great work, you've earned a sub and inspired another creator. Your English is really good by the way, I can see how much work you've put into it. Awesome job describing the why of the process to people as well, not just the how to of it. Strong work my friend

[@engjds]

DO NOT TRUST THIS GUY!, see my main comment post, I am all in for sensible designs, but this is clearly a very stupid design, get advice from people who do know, like say EEVBLOG, Electroboom and other guys like that, this is an idiot with a soldering iron.

[@Giuliana-w1f]

With the "don't ask me why" at 13:01, and the seemingly pointles caps at 13:14 that don't show the polarity in the diagram (electrolitics, one conected directly to the AC input, the other ones would get at least the 0.6v drop from the diodes at best, and full reverse voltage at worst), this could maybe be in the rectifier

[@fitito500]

A little question for anyone: if you only need just a hig voltage, it's not the same use the mechanism of a microwave? You have around thousands volts, a huge capacitor and a transformer could make an arc of 4kv ...... 🤔🤔????

Interesting video. I was surprized to see you using the cutter with no dark eye protection. The amount of UV that comes off a plasma cutter is pretty high I thought.

[@LiverpoolReject]

Yes, probably don't do any of this, but definitely protect your eyes.

[@taiwanluthiers]

Most of that light is under your cut, so you're not seeing much of it. Welding is different.

You need low-pass filter or similiar to protect the welder from high frecuency and high voltage from the flyback.

How do you keep the 40k volts from the flyback transformer from killing the bridge rectifier? The one he used wasn't rated for blocking that high of voltage. It would exceed the breakdown voltage and destroy it really quick

[@Chaosman88]

Don't you need some shield for eye protection, just like when welding?

[@Hellsong89]

All plasma arcs produce strong UV radiation that is not good for even skin, so long sleeves, cotton if all possible are recommended for any work related to plasma arcs. You can get away for short couple second burns when covering the arc with the nozzle, like with welding, but if there is any reflective surfaces you can get welders eye from even a little use and on the long term its not good for your eyes anyway, same thing with the skin. In short yes, unless you need to make just one or two curve cuts and do rest with grinder or other tool to finish the single job. Any multiple production and i would advice least automatic welding mask and welding gloves with suitable clothing that covers skin. Also use cotton or other natural fibers since if spark ignites them, synthetic clothes will catch fire if not fire proofed and if catch actually fire will melt to your skin. Its not fun scraping the burned skin off while removing the melted plastic off even if its small area.
