by far the most common comments I receive on this system is that I have the radiator plumbed in backwards because on cars the hot water returns into the top of the radiator and yes that is how cars work, but cars use the radiator as a reservoir for the coolant and the pump will draw water from the bottom pipe so that it always has liquid to pump.
my system the radiator is not the reservoir and if it had water going in the top hose it would be running out the bottom just as quickly so the fan would be trying to cool a radiator that is mostly full of air.
by filling it from the bottom all the air is pushed out the top hose and the fan is cooling a radiator full of warm water that then goes out the top hose into the reservoir to be cycled through the pump again.
I hope this explanation helps your understanding of this system and why it is made the way it is
thank you for your time and I hope you enjoy my videos.
^this guy seems to know what he is talking about^ lol
@@juscozcustoms The aluminum tubing needs to have a rounding lip swell in it, or some silicon or something like electrical liquid tape, wire hose claps are often used as there used on steam applications or high pressure. Could have used a fence wiring tool some ss wire or mechanics wire. tighter pull around the hose, the flat worm gear clamps are much wide requires them the go tighter to pinch vs a narrow pinch of wire - Engineer was told me that when I as working in the garage as a mechanic. Still I laughed when you turned it on, that puppy got a lot of pressure in it. What was the final cost of it? vs buying one. Now a days there's there not much sense in making your own. to save money. But custom is always good tho I like aluminum tank design, very well thought out. :)
I belive u that u been in trade for many years i have been foreman for many years for difrent companies my last one i was in charge of vessel shop runn for 7 years never had a mayor acident only minor injuries .the last years towers the last mont before i left thr company had a fitter cutting up some aluminum sheet with that same wheel u used .the pice he was cutting was not clamped down wheel got lock up on thr sheet n thr grinder bounced back lucky worker rapidly reacted n moved away from the grainer .good work u do take care of your self i dit asme work for 25 years in those years had mamy acidents working in environments were safety is a 1 issue .good video thanks . i now have a exhaust company been running it for several years now i havent had a acident yet thanks to the good lord .take care budy
yeah I have been in the trade since 2003 and about 8 of these years I have been doing alloy fabrication. as a first year apprentice a guy was trying to show me how to use an alloy death wheel and made a mess of his fingers. so I learnt how dangerous they are from the very start.
I did a death wheel demonstration video showing how dangerous they are

good luck with your exhaust business and stay safe this is my attempt at making an exhaust th-cam.com/video/XdIv5jRvqvI/w-d-xo.html
@@juscozcustoms thanks
I hear clamps work wonders for holding things still on a drill press. Maybe one day I'll try it.
Is that actually a thing? I saw it on the internet so i wasn't sure if it was true
I need to make a watercooler for my everlast tig welder. Nice job.
i will be doing an update video soon ;)
My airco water cooler is just a tank no radiator BUT about 7 or 8 gallons simple never gets too hot
Wow. yeah with 7-8 gallons you wouldn't need the cooler, I think mine is about 6 liters which is about 1.5 gallons and I could run it without the fan for a very long time. But the radiator was free so I added it just incase I got a little spicy with the tig because it has been known to happen occasionally
@@juscozcustoms yes, the one on my syncrowave is a large tank and coil, the backside of the pump/motor has the fan dial shaft motor
The worried Corgi inspector was the best part!
sometimes he is my harshest critic (usally when i have not given him dinner quick enough)
So how did it work out? Just bought my first welder and it came with a watercooled torch. Not what I was expecting! Cart and now a water cooler are on the project lists!
I am actually going to make a follow up video this week when i make the fuel tank for the cubman.
But whatever you do DO NOT weld with a water cooled torch if you don't have water pumping through it. they generally melt apart within 5 minutes of starting (I have seen it happen in a workshop). this could be helpful to get you started while you build a cooler of your own
th-cam.com/video/THu4aSj46bc/w-d-xo.html
juscozcustoms thanks for the advice. I actually read part of the manual for once, and read that same advice! Garden Hose with a few fittings should be me started!
yes as long as you don't do it for to long we had that system in a workshop once and the impurity's in the tap water combined with the copper wire and electricity flowing through it. well the copper wire lost that battle in about 10 months when it corroded away to nothing. we repaired it by shortening it by a meter but it was never the same. that is why the user manual says to use coolant or decriminalized water so that it cant corrode the copper
Awesome! That's a fun little project, I wish I didn't buy one now! But why not use a circular saw instead of that death trap!? and if you can weld that together, you can handle wiring it up. Cheers
Yes it is easy to wire it up but also illegal if your not a licensed electrician because it is running mains voltage. So I don't want to be setting a bad example in the video. I did wire up all the 12v side of things.
As for the death wheel well it's difficult to get a circular saw to do all the things that a 5 inch grinder can do. Sure a circular saw works well on flat sheet but that's only10% of what I need it to do.
just curious-why did you put the filler neck right behind the fan? Won't that tend to block airflow?
It is the most convenient place to put it for when the cooler is in operation because the welder is against two walls in the corner.
As for the fan it would be difficult to measure its effect on airflow but if you have seen where fans are mounted in old beige computer boxes they are generally a lot more restricted than this
Do you have a cap on the fill spot? You need pressure on the system for it to flow properly.
Yes there is a cap but it is only to keep the dust out of the system. I know that car radiators need pressure to work efficiently however the coolant in this is generally does not raise more than a few degrees above ambient temperature that is why i fill the radiator from the bottom so the water pushes all the air out the top so the radiator can cool it most efficiently before it gets dumped back into the tank
What is the aluminium tubing you're using for the plumbing? What do you use to bend it?
16mm od 12.5mm id not sure on the grade but it was just some left overs from a diesel tank I built at a workshop I use to attend 5 days a week for very little money. But I just used their hydraulic pipe bender with the appropriate size die and it bent nicely. I believe that with an appropriate size handle the $200 mini bender would do just as good of a job also.
Re: DIY TIG Cooler for $12 (US)Utilizes the pump intended for a fountain, a few miscellaneous inexpensive bits, and an old five gallon bucket. Hint: Please consider investing in a fountain pump with a greater flow rate (gal/min) or power (watts) than the absolute cheapest available on eBay and when satisfied buy a spare in case of emergency.Thank you so very much for your videos, I just discovered your channel...
thanks papa jon.
I watched "the fabrication series" video on using a pond pump for a tig cooler and he shows that it does work but was not a long term solution.
I found that a fuel pump worked better because they are designed to pump volume through a small diameter tube i first tried with the cheap carby stile fuel pump but it made to much noise for filming so I swapped it out for an efi stile pump in a follow up video.
I hope you enjoy the up coming videos
The Power of the pump realy doesnt matter anything above 2gallon/8l per hour are enough, no typo I mean per hour. Water can store alot of energy and a TIG Tourxh only requires 200-300watts of cooling.
Hot watter goes to te upper radiator hose and leaves cooled water for lower hose. The heat goes up all the times
yes that is how cars work, but cars use the radiator as a reservoir for the coolant and the pump will draw water from the bottom pipe so that it always has liquid to pump.
my system the radiator is not the reservoir and if it had water going in the top hose it would be running out the bottom just as quickly so the fan would be trying to cool a radiator that is mostly full of air.
by filling it from the bottom all the air is pushed out the top hose and the fan is cooling a radiator full of warm water that then goes out the top hose into the reservoir to be cycled through the pump again.
I hope this explanation helps your understanding of this system
That is AUsome! See what I did there? Seriously though, nice work.
that deserves a LOL. I'm glad you liked it
I understand this was three years ago and I agree your flow is not good ,I think your radiator tubes are to small in the core , most Tig radiators are 3/8 tubes through the core .the radiator that you are using looks like a flat style from a car . As far as flow top to bottom is really not an issue as your pump will push the air out . Try using a water cooler condenser coil as this will have either 5/16 or 3/8 tube . Or a radiator for a water cooled computer .
A centrifugal type pump does not supply enough pens per square inch for your coolant to circulate through your torch head. You need to have a minimum of 25 psi for sufficient cooling of water torch. I have used a 40psi sprayer pump from Remco with a bypass valve to control my pressure at 25 psi
How did it work out after longer use?
I did not have a temperature probe in it but the coolant never seemed to get warm even when doing longer welding sessions.
Nice build but how do you bleed the system when the filler is lower then the radiator?
thanks.
It is not a pressurized system like in a car so it does not need to be bled. the tank is at the bottom of the system so that the pump always has fluid supply then it flows the other direction through the radiator from bottom to top so as the radiator fills it pushes all the air out the top of the radiator and back into the tank that way the cooling area of the radiator has no air in it. there will be an air bubble trapped in the top tank but it will not affect the cooling ability.
@@juscozcustomsThanks for the answer. It was just a thought. I'm going to take a lot of youre ideas but mount the radiator a bit lower than the top off the tank. Greetings from Belgium!
Subcribed by the way. I've got the same book by the way 😉
cool I hope to see some pictures of the finished unit when your done maybe on the juscoz customs facebook page. I had many ideas like using a clear lexcen tube for the tank but that turned out to be to expensive for me to get the components where i live and even more expensive online somehow. and the book your talking about is that the locost clubman book? if all goes to plan I will be making a full size clubman next year.
@@juscozcustoms Yes it is the clubman book. I hope to move to a bigger shop so I can start to build the frame.
What type of coolant are you using? I like your design.
it is just automotive coolant and distilled water
you can't really use straight tap water in a TIG lead, because of the electricity especially in AC welding causes electrolysis that will eat through the copper cabling. It happened to a TIG I use to use because the boss did not want to pay for the watercooler and hooked the leads straight to the tap. then he had to buy another $500 TIG lead and a watercooler and that is when i got the idea to make my own cooler.
Thanks, my machine will be here Friday.
happy tiggin
@@juscozcustoms Could you please show how you wired it up. I'm ready to start building mine.
nice welding and would like to know the riveter and the saw blade?
ok so the riviter is

it works really well so far just don't go crazy on it.
as for the roatary hacksaw... watch this
th-cam.com/video/773WAG9on8U/w-d-xo.html
and then decide if you reallly need one
Been in the aluminum fabrication for a number of years (USA). We use similar blades, carbide tipped metal cutoff disk. Only thing we use them on air grinders instead of electric and always paddle with safety. Never an on off. Personally I think it’s the most dangerous tool I’ve ever used. Always use extreme caution. Fortunately nothing bad has happened to me but it easily could have.
Could you provide links on where you got all the fittings and parts please?
I will see what I can do in the update video that will be out this month. I have just ordered a new pump for the version 2 / rebuild of the water cooler the very expensive brass fittings came directly from miller USA. I will see if I can find the part number but if you have any welder that is not a miller then you will probably be able to get away with some thing a lot cheaper I will have a look for the ebay listing of the filler neck because it was a great product and I have brought more of them since and the pc fan and radiator where given to me but I will look to see if i can find an online seller. there should be a list of all the components in the update video later this month at which point I will update the listing on this video also.
Get a smaller filler rod for sheet metal, helps heaps
It was a 2.4mm rod on 3mm alloy.
The only real issue I was having with it was the gas cooled hand piece was not enjoying the amps I was putting through it to weld the alloy
@@juscozcustoms Yeah, for sheet metal 2-4mm I use 1.6mm, I find it far better. But I'm also using 4047 instead of common 4043 so that could be the reason too. 4047 has more silicone that's why it flows far better than 43
give it a go, you'd be surprised. it's even better for pressure vessels
@@rixogtr I generally use 5356 for most jobs and only go to 4043 to do cast alloy. The 4047 sounds interesting I'll have to try it out.
Thanks
@@juscozcustoms I also found that 4047 out of all those three mentioned filler rods is the best for welds that are required to be fluid-tight. I use that on all oil coolers, inter and charge air coolers, radiators, etc. When I was using 4043 I had leak issues at high pressures due to the low amount of silicone, but 4047 changed the game completely, give it a go and post some video trying it :D
@@rixogtr sounds good. I was planning on making most of these things this year (2021) now that I finally have a speedwerx bender something will be getting a tube chassis and a K24.
I'll have a think about how to test the different filler wire for a video. I already have a few ideas.
Thanks for the imput
How much pressure is on the return line to the radiator?
None. There is a 4mm ID line coming from the TIG lead and it goes into a 12mm ID pipe then the radiator and the top side of the radiator is another 12mm ID pipe that falls back into the storage tank so there is no way to build any pressure after the TIG lead because it is practically open to atmosphere once it comes out of the TIG lead
Hope this makes sense
@@juscozcustoms ok so there is no way to know if your flow has stopped if the return line get's crimped or blocked?
@@juscozcustoms or do you have a pressure switch after the pump ?
@@skinnycains4448 I was thinking about fitting one when I built it but if it stops working it stops making noise or blows a clamp from to much pressure and makes a lot of wet noises and that was not a fun day
@@juscozcustoms thanks 😁👍
Desperately need to know the part number/ link to the send and return fittings you used
I have been looking for an hour for the information. I assume you are talking about the very expensive miller parts. I will keep looking and get back to you
juscozcustoms thank you so much
sorry that it has taken so long to find the information and I hope it is still relevant to you but the very expensive brass fitting from miller has a part number...
MR166571 (FTG COOLANT BARB 3/8 TBG 5/8-18 FEMALE)
now this is the part number from the Australian miller importer/supplier
WIA welders so I hope that it is a miller part number and description that you can use
They are called a death wheel because they explode, I gotta scar on my arm from one
that is true. I was referring to how much more dangerous the alloy cutting wheels are so i made a video about them if you are interested th-cam.com/video/773WAG9on8U/w-d-xo.html
@@juscozcustoms so does the rpm on the grinder match the rpm on the circular saw blade?
Probably not!... nice build
The cirular saw blade is fitted to the 5 inch grinder so it is doing just as many rpm as the 1mm cutoff wheel. They are both dangerous in there own ways
Hey, how did the pump go? Did it have enough pressure. Also was the radiator big enough?
The Davies craig pump had a bit to much pressure... one of my hose clamps blew apart so I went to an EFI fuel pump because they are designed to pump through a small diameter hose. But I brought the cheapest pump I could find and it stopped working so I went back to the davies Craig pump
I see, I’m running a small 17LPM 45psi chemical pump that I have on my weed sprayer. Just not sure on radiator size?
I have around 8 liters in my tank and it probably would not change temp unless I was cranking 300 amps for an hour straight (I have done that before) so I just used a computer radiator and had it pumping in the bottom so it fills up up and pushes out the air so it cools better. But the radiator is not super important unless you are pumping a lot of amps for a lot of time.
What thickness is that aluminum for the box you made
It is all 3mm thick alloy.
Hi, what power suply is used to power the the pump?
It was a waterproof 240 to 12v garden lighting power supply. They come in different amp ratings I think mine is 12v 120w and can be powered by 120v to 240v so it will work on am American power supply. I also have an American power cord wired to it so it plugs into the back of my miller welder and automatically turns on whenever the welder is running. I brought it on ebay so I can't give a link to where I got mine but it shouldn't be too hard to find searching for garden lighting power supply. Just make sure you have enough amps to power your pump.
@@juscozcustoms Maybe you migjt tell how much of those apms it uses?
Nice wire feed
with the tig filler wire? its weird if I try to feed filler wire while I'm not welding I cant do it but when the hood goes down everything just flows

Get yourself a decent solar shield
The problem I have with solar shield's is that when I start fabricating I start with the heavy breathing... then it fog's up
more dangerous the piece you hold with the drill.
I do need to get myself a drill vice but I have been doing this for long enough to know what is dangerous. So the two things that make drilling holes more dangerous are the size of the drill bit the bigger they get the more dangerous they are and the other thing is the size of the piece of steel you want to put a hole in because the smaller it is the more dangerous it is.
learning what is safe is the hard part
Would of been more useful by providing information on the pump (at least a part number) rather than watching a box being made.
thanks for the comment, the information is in the second line of description along with a link to the Davies Craig page with all the specifications about the pump.
Which means percentage wise you're due for some kind of catastrophic failure and bodily injury the longer you're into something sooner or later as a person who has been in a trade for 40 years I've had mine several times broken bones crushed foot and a bunch of close calls so I don't know if that's a good thing to say I've been in it so long is the reason I'm doing something dangerous if anything percentage-wise that is we're talking about you do God save you and bless you in Jesus name
Well I have had my share of misfortune in my years as a fabricator with more than a couple of stitches but the worst was in 2018 when I dropped a motorcycle and destroyed my knee and spent 6 months on crutches so I started a youtube channel
Wrong connection dude
Care to elaborate?
lmao
it really did hit the fan...
