Any problems cooling water torches 25' long with home made pumps?

admin

I got all my pieces. I'm waiting on a procon fountain pump to arrive so I can piece it together. Just wanted to see if anyone had problems with 25' cables or should I use 12' ones for easier water flo? The length doesn't really matter that much since it's gonna be on a cart. Almost forgot. The torch is a Wd-20 tig.P.S I will post the pic and where I got he parts in the project section when I'm done.
Reply:Wha is the GPH rating of the pump? I would imagine that it would be O.K. in any event. The only problem I would foresee is that the pump would not last too long is it didn't have a good GPH rating. If you got some plans, I would like to see them.
Reply:GPH means gallons per hour.Hope that helps.Will   Supports Autism Awareness                            My ToysBobCat 225 PLusMillermatic 130Miller Spectrum 300 CutmateEverlast Power Tig 185 Micro April is Autism Month .
Reply:ok...I got my specs from here.http://news.thomasnet.com/fullstory/15298/1033"device features an internal ProCon® pump with industrial, heavy-duty motor, which delivers a maximum pressure of 60 psig and a maximum flow rate of 100 gph."So....I went to ebay and found this.http://cgi.ebay.com/ws/eBayISAPI.dll..._BIN_Stores_IThe will set the pressure at 60psi , no charge. I already have a 1/3hp motor, so the only thing I need is a condensor from a car (friend is getting that) and II figure to use a 5 gallon container to store the water. With that pump and all that....I should be cool as can be. Even if I ran it all day.My only concern is/was(?) the lengths cause it's not just 25ft. It's 50 cause it's gotta come back.Last edited by jquest; 01-15-2006 at 12:36 AM.
Reply:That's more than enough. Should not have any problems whatsoever.

Reply:You need 50 to 60 PSI (input pressure) at 1 quart per minute (minimun) to cool an HW-20. Check the flow rate, of the water coming our of the torch, with a 1 quart mason jar. If you have any doubts invest a few dollars in a fuseable power cable adapter. Don't be surprized if your local "welding expert" salesman has never hear of them-they just want ot keep selliing you new tig torches!
Reply:I have used a gear pump with a spring loaded bypass for many years.  The bypass regulator has a spring loaded ball that allows the excess coolant to go back to the tank.  Just set enough pressure to get a small stream.  I'm sure GunnerG is correct on the quart a minute.  If you do go that route, be sure and get the brass body pump.  Got mine at MSC.
Reply:Hey, I didn't quite make my own cooler, but I got a unit from a guy on ebay that somehow got a lot of old stock from Lincoln. It's the same cooler in the drawer on a Lincoln Precision Tig 275. Anyhow, I am building a case for it all so it doesn't look out of place. I found a neat flow indicator on a Miller CoolMate 30. It can be panel mounted and simply spins when the water is moving. Don't rely on a pressure gauge, the torch could be plugged and the pump still has pressure, but you are not cooling. My local repair shop ordered one for me today from Miller for $23.00. As luck would have it for me, they are on backorder.
Reply:I made that post and then today....while I am waiting for my flow indicator, I was welding some schedule 40  4inch Aluminum to a piece of 1-1/2 of same base material when I heard a loud pop and hiss. My kids were there watching me and asked what it was. I looked around....couldn't find anything wrong and got back to the puddle and then that's when it hit me.....but it was too late.  My water cooler failed and I now have a nice melted power cable from my machine to my torch. Arrrrgghhhh!
Reply:WOW. This was really weird. I have never seen this before, but there was a clear jelly goo that was plugging the outlet from the reservoir. Some of it had been sucked into the inlet on the pump. Both the pump and the outlet of the reservoir were plugged so well that I could not blow it out manually. I had to use the air compressor to blow it out. I flushed the entire system out and cleared it and let it run (without a torch) and it works great again. Now if only I could fix the power cable. I hate when you let the smoke out of the power cable. Every time I see someone let the smoke out, they can never get it back in. Go ahead and try to find new smoke. I can never find it.  Anyways, I was pushing that weldcraft 225 with 250amps ACHF, I know that's pushing it, but I honestly believe it would have been fine had I not lost water flow. So going back to my previous post......GET A FLOW INDICATER along with a pressure gauge. Monitor all of it if you can. No sense in losing a 100dollar power cable to stupidity (as I did).
