Diy tig cooler pump.....

admin

Looking to make my own tig cooler ,just unsure of the pump.Doing some research on the web and it seems that many people are using the procon pumps. I found a Procon CMP-7400 pump local for $100 brandnew. Just wondering if this is a good pump to use. Heres the link:http://ontario.kijiji.ca/c-ViewAdLar...AdId=434004136
Reply:there are several threads here on this subject, just use the search option and they should come up, myself as well as others have postings here with photos showing detailed info.
Reply:Yes, they are good.  But for $120 I bought a "big mac carbonator" off of ebay. It has the pump/ motor, but comes with a large SS tank and a pressure relief valve to adjust the PSI. It took me $10 of fittings and works great. and with the size tank and that its SS (and the fittings are all brass) its low maintenance and always seems to be cool water. Just another option that has worked well for me. Lots of pictures on here and google of it, but if you need help shoot me a message.
Reply:Hi, if you want to go completely DIY then some years a go when I worked as a welder the guy I worked for needed a cooler for a submerged arc set-up, and we built one using the heat exchanger and fan from a car's heater unit, stripped down to just the brass finned core and the fan.The parts were assemble into a metal box and a pond pump was used to circulate the water to the welder gun and back through the cooler core with a 1 litre reservoir tank in the line.....the unit held about 2 litres of water total and the fan from the original heater kept the water cool.As the original unit was from a car heater it was 12 volt, so we powered it from a 12 volt battery and just kept it charged up as needed for simplicity, but we could have had a 12 volt power pack to supply the fan if needed, and with hindsight that would have been the better path to go.The pond pump was rated at 240 volts so it was seperately wired to plug into the wall socket.I think the total cost was for a new 12 volt battery and the pond pump, and as we already had a charger the other parts being from a scrapped car, it was just a few dollars at most.You don't need a large amount of water, just enough to keep the reservoir full and allow for evaporation or leaks, and we used the same water with rust inhibitor as you would use in a car cooler system to prevent corrosion.....no anti freeze property needed.The reservoir was a plastic bottle and a slotted hole in the side of the casing showed the water level in the bottle.Piping was with 3/8" bore clear plastic tubing.

Reply:Procon pumps are the favorite and are what is used in many off the shelf coolers. You just have to open up the relief valve adjustment and dial the pressure back to 40-50 psi for your torch. I personally bought a carbonator off a used restaurant supply company locally. The tank that comes with them works great, especially since it has a dip tube in it, so the feed to the pump can be plumbed from the top.
Reply:ok thanks for all the replys. I will try to find a carbonator online or from a local restaurant supply. That looks like the best way to go.
Reply:I was gonna build a DIY cooler pump about 4 months ago until I started adding up the cost of everything and found a used lincoln magnum 10 cooler on ebay for $150 buy it now with free shipping. I was gonna spend at least that much if not more to build my own so I bought the lincoln and it works great.Last edited by down19992000; 01-01-2013 at 12:44 AM.

Reply:i think i found a good carbonator locally. Let me know what you think.http://toronto.kijiji.ca/c-buy-and-s...AdIdZ433364875
Reply:Yeah if you scour Craigs or Ebay you may get something... but patience may eat you up first... Here is a cooler I rebuilt/harvested parts from an old Bernard cooler. Tank was toast so just made a new cart and used an old oil reservoir that already had some NPT bungs in it to speed things along getting it made. Have little to nothing in it but finding the procon pump / motor is key. Attached ImagesLincoln Precision Tig 185Miller 180 Autoset
Reply:An immersable pump from Homedepot in a 5 gallon pail of distilled water works too.  You just need a pump that will push a liter a minute through your torch.  That's what my CK 20 series needs.  Even hooking it up to my anemic city water, which is only at 20-25 psi worked out to be enough.Then you have time to look for a cooler.  I bought a real Miller Coolmate 3 on eBay for $100.  It was rebadged for a Japanese company.TA Arcmaster 300CM3XMT 304S22P12 suitcase feederX-Treme 12VSOptima pulserTA161SMaxstar 150STLHypertherm PM45OP setupStihl 020AVP, 039, 066 Magnum
