Just seen the plasma cutter video and was just wondering why no more videos

Awesome! Thank for your advice!

Back again.

This method is used commercially with some sodium nitrate added for some reason. We used it for very fine fragile wires in a cryogenic application where nicks could have cost $millions if the wire broke.

Great info... I now have at least a clue to begin troubleshooting...just watching this I suspect one/some of those big diodes causing AC into the protection "thingy".

Does anyone know where I can find the electrical diagram for this machine, as it goes into protection and lights up a green LED on the board itself, thank you

Could you help please, my plasma trouble running kzbin.info/www/bejne/eYvTc6uDbs-ehrMfeature=shared

Is there any way to derive position from the pwm signal? I’m trying to replace a galvo scanner with one of these, but I’d need fairly precise position detection or prediction.

Hi, I have a question, maybe you could give me some advice. I would be very appreciate . I bought a Longevity Force Cut 40d and found it not working, but after bridging the overheat fuse it started and working. However, when I press the switch in the gun, nothing happens, but this does not mean that it is damaged, because I checked it with a multimeter and the switch works properly. I think something is damaged on the bottom PCB board and the relays are not turning on. I took out the board but I don't know how to check it with a multimeter. Can you help please.

If you knew how much you could sell that knife for (potentially) then you would probably stop using a hammer on it. I'm not certain but it looks a lot like mine, though the handle is a different color tone. (I accidentally broke 1/4" of the tip off of the blade and then found out how much it would cost to replace it). Could you tell me about any names or characters on the metal part and I'll let you know if you have a winner. Btw thanks for taking the time to explain how to open those things; its too bad that they just can't put them together with screws but the glue is probably much less costly.... Best regards...

We have a deaf cat that adopted us a few months ago. She’s started spending more time inside. We were REALLY confused when we started hearing these sounds. We’ve now learned it was directly related to the random socks we find around. She hunts socks and this is how she lets us know. It’s intense but now we understand.

Try a Needle Threader

What role does the 1mhz clock signal play in this? Is it controlling the laser's gating, or the motor? It sounds like the motor's speed is controlled exclusively by voltage, but it also looks like laser is just a handheld source... what is the 1mhz signal doing?

Hola amigo será posible me ayudes con una información , mi máquina le conecte 110 V en cada entrada y tierra también, ya no prende. La máquina tiene fusible o protector de corriente.

BUENAS TARDES QUE SUGERENCIA PODRIA APORTAR A LA PERDIDA DE FUERZA DE CORTE DE UN PLASMA DE 150 AMP

And I thought MY car is driving me crazy! Yikes! After she became deaf a couple years ago, my orange 18 year old cat does the exact same thing sporadically, but not in such a long stint. It’s as if she’s in agony or even lonely. I’m home most of the time and she has everything she needs. Vet said bloodwork is fine. Just wish she could tell me what’s going on. :-(

Your method worked, thanks.

I still love this all these years later.

So what blew up on this machine and what was the fix? I don't see any burned boards or anything. My Cut50 packed it in suddenly after about two hours use so I'll refer to this video for trouble shooting it. Thanks for posting this!

Informative, but the radio playing in the background is VERY distracting.

Thanks so much

I used a utility knife to cut the heat weld and it cracked right open. I can't believe you said, "Salivation Army." 6:25 lol.

My deaf cat does the exact same thing.

5:45 - 6:35 Recycling FTW let's goooooo!!!

Aww, poor thing. Rest in peace, STH-10. 🥺

why

Instead of wasting time on a bunch of nothings, screwdrivers and compounds why don't you go to the meat of the matter. How do you determine which pins on any laser diode connects to what? And how do you know if any of the laser diode is good or not in the first place, using a multimeter? Look, it is easy and simpe to test a pin diode. That is not an abbreviation by the way. A pin diode is your typical two leg circuit diodes you see everywhere. The long leg goes to positive and the short leg to negative of the power supply. If you want to know how to check these diodes uisng a multimeter, you simply put your mulitmeter on diode mode and probe the two legs. If you place the positive of the mulitmeter to the long leg and the short leg to the ground negative of the multimeter, you will see the led lit up if it is good. Straight forward and to the point. Now how the hell do you check these laser diodes. mr expert?

esd? What is that and why people just want to abbreviate things/ Is it a show off, that I am educated or people are to f-ing lazy to say a complete word, or is it that suddenly time is too precious to waste on saying the full word. Either way.... people are dumb, impolite, rude, egotestic adulescent wanna be's that can't wait to throw it on people. They the other same types who do the same thing back them up. No different than them street gangs lingos. These same gangs mentality moves over to science. No different..

good afternoon friend... a greeting from Venezuela... I have a hoffman saw 40 plasma machine... I want to get the diagram of the upper plate for this machine... to see the values ​​of the resistances of the upper plate since burned one that is there but I don't know the values ​​because it is burned... I don't know if you can give me your contact number

I love cats. I love the sounds they make. I love their little personalities. I also love the people that love them. What a joy you have in your life! My cat can sound like this, but only with a toy in his mouth and only when he’s “strutting his stuff” haha! It happens almost every night at human-bedtime. I liken it to the big boss Lion strutting back and forth warning the jungle not to mess with his family while they’re sleeping OR ELSE! 😹

Change playback speed to 2x. Otherwise you will want to eat the metal shavings and throw yourself off a cliff.

hot weather makes me so miserable, i've thought about holding a flashlight in front of my riding mower. mosquitos are too bad to use the push mower at night. i would totally do that. i have mowed the front yard at 11pm. i thought it was 10. it's electric, so not loud. i don't care if people think i'm weird, i just don't want to keep anyone from sleeping. i also don't care about the grass, but the city will complain.

actually you can modify this machine to a 3 in 1 stick/tig/plasma. that;s what I've done with mine if you take a look at 9:44 next to the blue capacitor there's a connection soldered together, just put a toggle switch to connect and disconnect. if u disconnect it then the welder output will always live for stick welding, the tig switch solenoid and the HF will not working, if it connected then it will work for tig and plasma

Good vids' can I ask a silly question. is it possible to connect a non pilot torch to a pilot plasma machine as I like the idea of using a touch arc instead of a pilot arc for plasma cutting. I have a cut 50A machine.

You may not respond seeing how old this video is, but would hot glue be a safe substitute?

Why did you not show it balanced on the lawnmower blade balancer? Did you get it balanced?

Looks awesome! I am trying to make one like that, and you really helped me! I appreciate it!

Fair play on explaining 👏 thanks don't worry about the slow speech no one's perfect at least yr original keep it up

My granma chewed my cord up. She don't see too good and thought it was some licorice. Good thing it were'nt plugged in.

Can you wire up two small plasma cuters together, I have a 40 cut & a 50 cut

Please don’t make videos under bar light. I respect you and like your explanation very much. But unable visualize

Is it possible to convert a welder in to plasma cutter .....with changing some circuit board .....coz its preety same as a inverter tig/stick welder

Sketchiest setup ever... stuff like that will get you killed and I wouldn't recommend this to ANYONE...

I wound up running this at 2x speed and found it much more tolerable. However, the background entertainment was just continuously annoying. However I do appreciate his willingness to give helpful advice on opening these devices. Thanks

Seems like a lot of work to fix a $10 part.

Thanks George McFly!!! Great tip!

My 19 year old cat has been doing this for 6 months. I've caught her doing it into a corner a few times. I'm a singer so I know that is a technique to amplify your voice. She does it many times throughout the night too. As well as every morning until everyone in the house is awake, so she can go to sleep. 😒
