The Ultimate Portable Welder!

[@Vikingwerk]

Now that is badass! I’m honestly surprised no one is manufacturing this already.

[@cranktowncity]

I was surprised too!

[@bigclivedotcom]

There are complications in having a grounded box that is worn like that. It would be a liability nightmare for a manufacturer. A common power distribution system that combines neutral and ground has a major flaw that when the common conductor fails the current will find a path to ground via the ground wire, and that poses a risk to someone outside a home holding (wearing) grounded metalwork. A GFCI can't help in that scenario, as the ground itself becomes live.

[@Vikingwerk]

@ I’ll admit, I don’t understand your explanation because electricity is danger pixie magic to me half the time, but thanks for explaining. I guess that makes me wonder why the first welder he showed exists, as it is functionally the same?

[@bigclivedotcom]

@@Vikingwerk Given the choice I'd rather have a shoulder strap type so I could have a chance of dropping it if things went wrong. If a manufacturer made a backpack unit it might need to have a plastic case to avoid the risk of current flowing to the wearer via sweaty or wet clothing. Grounding is a complex subject and although it's relatively rare, you can sometimes end up with a significant voltage between electrical ground and actual ground.

[@Vikingwerk]

@ aah that makes sense, thanks!

[@ianrwin]

This thing is awesome! I could see it being tiring, but for the fencing situation you're talking about it's probably way more ergonomic than carrying a welder on one shoulder

[@GigaVids]

id love this thing for fence and handrails

[@tau9632]

New purchases are not the perfect, shiny, completed product - they simply arranged the raw materials in a convenient way for us, so we can build the thing WE wanted to build all along! That's how I like to see it anyway :D

[@sydnerd]

New Cranktown City video?!? Instant watch ✨ The sheet metal work is incredible, the final design just so great. Also love you went to help out a friend to test/demonstrate the Stinky Bag

[@noanyobiseniss7462]

I'm a Marine that has humped a ton on my back all day and while you were building that I was like NO not More Steel !!!!! :D Love your shit man. :)

[@kechidonick]

My favorite part was when he said "It's welding time!" and then he welded everything in the workshop and his house, truly a welding of all time.

[@mrd1323]

i would like it if you posted more regularly. You are one of my favorite KZbin channels. Entertaining and informative. Thanks for the videos. Keep up the great work.

[@Doc_89]

Somewhere to hang a pair of snips, a pouch for some spare nozzles and you're right as rain. A nice bit of kit that is, I am impressed.

[@Baxteen1]

That was pretty cool. I was expecting it to be plugged into a portable battery and to be sponsored by eco flow. Honestly this was even better

[@joshbolen6515]

You're my favorite channel on youtube, dude. Your content is awesome, and your sense of humor is quality. Thanks, man.

[@floshey]

No man should have this kind of power

[@Bob.Jenkins]

You buy something and immediately take it apart - that isn't a problem that's just innate engineering curiosity and this habit has probably saved my life on two occasions... once when I purchased a new Benchtop Power Supply on eBay only to discover that if I'd plugged it in, the entire metal body would have been live (and here in the UK, that's 220v) and once when I purchased a small, jobsite Table Saw from Amazon and noted that half the bolts holding the damned thing together were loose. Great video by the way and the end result was awesome !

[@kimberlyjacobsen4148]

Am I the only one who get proton pack vibes 🥰 WHO you gonna call ? Cranktown city 🤟

[@madnessandescapism]

this needs ghostbusters soundtrack :)

[@LoremIpsum497]

was just about to comment ' whoo ya gonna call?"

[@iamphloyd]

Damn fine build dude! Thanks for letting us come along for the ride!

[@LoremIpsum497]

this guy is a genius, if i could by this on amazon i would.

[@Alphaseen]

That's awesome. I would add a set of pop-out feet so you can set it down easily. Also you could add a small plate on the belt front for hooking magnetic angle holders on it. Get ones with an on/off switch so they are easy to remove from it, but wont get knocked off. Also maybe a small 3d printed one-way venting over the vent holes to stop water from being able to fall in it.

[@shouldb.studying4670]

A hero is born.

[@waldobean7534]

Now this is internet content! Raw engineering.

[@elijahperry781]

now make a backpack sized tig. plenty of small 120V tig machines, paired with a small argon bottle, you probably could come up with something pretty small. Its a project i've been wanting to build, a small tig rig I could keep in the truck of my car for emergency repairs and such.

[@cranktowncity]

I really like the idea of having a little argon cylinder on my back. Very star wars like haha

[@McNeillWelding]

Reminds me of 6061 filling a balloon with argon and riding his dirt bike to weld his buddy’s bicycle to a fence post 😂

[@danmurphy5660]

New Cranktown vid day is a good day. Love watching you work mate, especially all the precision eyeballing.

[@tau9632]

That is honestly such a sweet setup

[@billhacks]

What a holiday surprise! I've missed your videos. Definitely a dinger coming your way.

[@klausnielsen1537]

You are not alone. The humour and the I don't brake for anything attitude makes the already great projects epic entertainment. Like the sticker on the welder backpack😂👍

[@AW-Services]

Awesome video. That rucksack frame in the intro reminds me of all the pain I suffered in the 80s on expeditions. I'm glad they got phased out. Happy holidays, merry Christmas CrankTown crew

[@DOCTOROCTAGONAPUSS]

Tool battery powered mod when?! Excellent video, as always.

[@greengreens9936]

Smack 6x 18V battery packs on it and you got a portable welder. Those welders function like a SMPS and can take DC as well as AC.

[@DaleM1980]

There's very few creators I wait for on KZbin, you're one... AvE, Project Farm and Torque Test Channel are the others. Awesome builds and making me laugh. Keep em' coming!

[@alexdrockhound9497]

This old tony?

[@DaleM1980]

@alexdrockhound9497 absolutely him!

[@erikslagter3231]

great fabricating again. Love the stinkin electric.

[@Biokemist-o3k]

Super cool!!..A new crank town city video..Hell Yeah!!!-John

[@AlbertFilice]

Logo and paint job are really on point

[@Universalhiccup]

I like your videos before I even watch them,,,we love your content from the UK respect dude

[@qwertbochaffer]

This man needs a Bambu Lab sponsorship

[@JMassengill]

great to see you posting again. excellent video.

[@mr2ferrari]

Legendary build sir! Secondary decal option: "frickin eclectic" I expect harbor freight to have a backpack option in their lineup within the next year after seeing this!

[@aerodesic1]

Thanks!

[@cranktowncity]

No, thank YOU!

[@jondavidmcnabb]

The Bob Ross of Fabrication!!! OMG you are hilarious!!!

[@fb___4255]

Your channel is always entertaining and fun to watch. Keep it going man, hope you're doing great!

[@PatriotPainter]

Cool idea! Looks like a Ghostbusters proton pack.

[@4tibonn]

If it works .... as that obviously does, it's not stupid. Awesome video, thank you.

[@brocksterification]

Made my day seeing some more CC content pop up dude!. You should sell those backpack welders!! Merry Christmas..🎄

[@FernandoDelgadoBuchelli]

Genial!....se te prendió el "foco"!!!!....tal vez fabrique uno!...con mi propia marca!

[@Mr0Randomness]

Pretty wicked project brother!

[@brandonfranklin4533]

Hell yeah that’s awesome bro!

[@irkedoff]

Always entertained and interesting projects. Thanks.

[@texasmcgyver]

Good idea , reminds me of the proton packs from the original ghostbusters! I might have to attempt a similar build using my stick welder!🇺🇸🇺🇸💯💯

[@kfmutrus]

Ha-ha, I love that vibe “I have an idea, but not so many ways to use it…still doing it!”. Maybe adding RCBO to the pack would be a wise idea, in case a welder will suddenly take a break from life while it’s on you.

[@badmacdonald]

yet again, genius.

[@douwetendam5097]

Looks great!! For thin tubing and femcing work i can definitely see this come in usefull:)

[@Convolutedtubules]

Your sewing is mint 😁

[@philpage9942]

Great original ideas - well done as ever and keep it up.

[@bogmaerke]

Shameless Creality plug, Next up 'Bambulab sent me this thing to test' 😄 let's go mr. CT

[@cranktowncity]

Fingers crossed lol

[@patrickcunningham1242]

This is a sick project! I would love to replicate it some day and add in a lil 120 stick welder option too.

[@TheRealFOSFOR]

Super Sweet! Maybe a stick welder would be a bit better for stuff like this... but ... Super Sweet!!

[@wylde780]

Well done, and those shelves look great. I remember watching the video of you building them, but they stuck out to me in today's video.

[@BadgerBishop]

What else do you need? Make a spot on the shoulder harness to put an f clamp(or 2) and/or a couple welding magnets.

[@ElevenElevenAus]

Another great video. Go Batman. Awesome.

[@MadScienTEST]

Awesome idea. I wonder if you can fit some type of auto height leg for a support brace. Like a pole from a tripod or something where it can slide up but not down. push a button and it drops down from the welder and hits the ground taking most of the load of your back. Use it as a built in stool like the doctors use for surgery. 🤣 Cheers 🍻

[@dean9498]

"Stinkin Electric "power zapper 120. Frickin genius. You should patent it...

[@RogueRestorationsLTD]

Congratulations you bet Colin Furze with that bad boy . nice tasty build Happy Christmas im stoned !!

[@peterhaan9068]

Patent your idea! Place the wire roll at the bottom instead of the top which will take a lot of the strain off your back. Build a collapsible frame so you can brace the back pack to stand up when you aren't wearing it! Will help immensely when you go to strap the welder to your back. Put the power switch on the same chassis as your control pots, which by the way SHOULD HAVE A BAR IN FRONT OF THE KNOBS TO PREVENT BREAKING THE SHAFTS! Move the whole assy away from your back to allow air to circulate. Speaking of air circulation place a screen in front of the fan to keep stuff from getting sucked into the innards! If you feeling particularly squirrely, source portable Li inverter battery to remote power your welder so you won't have to be tied to an outlet. Modify a dolly to carry the welder, gas tanks supplies and maybe the portable Li inverter should you go in that direction.

[@DIYBuilds]

very nice

[@usarms149]

Outstanding, dude. 👏

[@patrickkenny2077]

Very cool. Great job.

[@theclintified]

Its a great idea for sure!

[@yoti-fab]

Cool build! Add in a holder for some MiG pliers!

[@JonesMetalCraft]

You need to market that thang!

[@HyRkt]

Thats pretty fricken sweet

[@Convolutedtubules]

Taking things apart is an addiction deeply seeded from youth.

[@gutsngorrrr]

Once you're used to the weight, you can then add a big backup battery to run it from, to make it totally portable.

[@joels7605]

The amount of power you can push through a transformer is proportional to frequency! If you look at 1980s computer power supplies they had tiny wattages and weighed a TON. That's because their transformers were running at 60 hz from the wall. Then they made switching power supplies that ran at hundreds of kilohertz in some cases, and the power supplies got really light AND their power ratings went through the roof.

[@dj1NM3]

Apparently this was applied to aircraft electrical systems, at least as far back in the 1940s: the electrical systems on Allied bombers operated at 400hz, so all the power-handling components could be smaller and lighter, particularly transformers.

[@joels7605]

@@dj1NM3 I like that piece of trivia. Thanks.

[@CreativeWerxGFX]

beautiful work btw!

[@richardsavage2]

Great idea. You might improve the comfort during periods of extended use by transferring a high proportion of the mass from the shoulder straps to the belt which you tighten around your hips. The shoulder strap should only stabilise the load. Can help with plasterer's crack too ;-) Merry Christmas etc

[@philanderingwhitecollartra8281]

all good but i would have put the spool on the bottom for better weight load distribution and maybe down port the gun cable.. maybe a backing pad if the frame tube digs into you stinkin electric.. awesome

[@dcmotive]

Awesome. Wonder how far a lithium power supply would get you on a fence run. I could see using some kind of power supply if you had to do some fencing on a farm or property without much power.

[@cranktowncity]

It would be so sick to run off battery power but I think it would be wayyy too heavy

[@spookydonkey2195]

Power Zapper 120 is amazing. Could use chest rig with square, angle hoot and what not. Maybe a drop leg hammer/pryer holster.

[@megadeth369]

Love the channel!

[@Nobody-Nowhere]

Next up make an exoskeleton for it that grounds the weight while standing, with some spring assistance to help raising up from a crunched position. Could be cool and not that difficult to make maybe. Nomad Contrafact has some of those non powered exoskeleton projects.

[@cranktowncity]

Oh shiiiiit and exoskeleton would be a good way to deal with the weight of batteries. That's an awesome idea

[@ahbushnell1]

I"m impressed

[@TheRageface13]

Dude that's awesome. Great job! Definitely inspired my lazy ass lol

[@GigaVids]

love it, wish they sold this .

[@icmpeko]

Haha, nice - nice to see ya again! 🍺🎅👍💥

[@Nobe_Oddy]

This was FRIKKIN AWESOME!!! And you'll put it to use before you know it! Just gotta make sure you setup a place to have in hang on the wall where you're gonna keep all the projects you make on the channel.... and you'll show it in the last shot of all your videos, the way you showed you bad-ass Cranktown sign in the last scene of this vid... it ain't gotta be prominent and right there in your face, but just make sure it's visible in that last shot.... But then if you run out of room you kinda re-design the whole wall storage look and start a New 'season' of Cranktown City and start hanging up the new stuff you make.... - - Just an idea... but you really should make sure to have in that last shot of your future videos.... it's like free advertising of your previous videos.... and that's good practice ;)

[@ewasteredux]

I like the parallel of it looking like a proton pack. Might make a great name for it (or some derivative). Maybe you could wire up an arduino to have it make the sound effects of a ghostbusters backpack.

[@cranktowncity]

Hahaha that would be awesome

[@icemanfiveoh]

Nice Proton pack Egon...

[@scaytrase]

next step you need battery and inverter. nice job!

[@MakerMadness]

I live in the Valley. Love your vids, bro. Oh, and none of my new tools make it past day one without it being taken apart first.

[@LittleGreyWolfForge]

2:49 harbor freight being better quality is CRAZY 😂

[@Richard-vw8no]

I'm speechless! How do you come up with these priceless ideas?

[@AFMR0420]

Told my friend to make a back pack welder like 2 years ago. He didn’t. Now build both of them into the unit for tandem welding.

[@greengreens9936]

Nice job!

[@AndrewSpencer2]

go go gadget welder!

[@curtchauvin5303]

Freaking sweet! I think you could add some cleats on the side to hold an extension cord . And you forgot the cupholder :D

[@mariomarchigiano528]

I really like this

[@_Funtime60]

Maybe there's a small enough power bank that you could hang off the bottom of the back pack like those WWII parachute positions? Might also "solve" the plumber issue.

[@AC-vx3jz]

Dude your videos are so good. Stoked to have this to watch on a Friday night while I mess around with my new 3d printer and CNC router

[@HMPirates]

I found the K1 max bed to be extra finicky. Can't have it dirty at all. Dishwashing soap and give it a real good scrub with a newish Scotch Brite. Then a quick coat of glue stick. Or replace it with an aftermarket bed plate.

[@jasonkieger9249]

Fine, Fine, I'll do it! Attaboy

[@McNeillWelding]

That thing is sweet. Maybe an aluminum case for next iteration to cut down on weight?

[@AdricM]

Now you need one of those big wheel around rechargeable power station thingums.

[@thewrenchreviews9986]

Now to refill small propane bottles with welding gases of various types, to make it mo bedder?

[@bheckel1]

all metal all the time!!!!!!!!!!!!!!!!
