PSI/GPH rate of coolant pump for TIG torch??

admin

Hi guys.   I finally got the new TIG machine (Thermal Arc ArcMaster 185 ACDC) and I got a water cooled torch (CK20 with a built-in finger control).   Now I'm making a water cooler for it.   I have a 2.5 gal plastic bucket and want to submerge a pump in it to pump the coolant throught the torch.   I figure some kinda fish tank pump would work for this.   Any  pump that is submersible and runs on 115v AC with the right pressure and flow rate should work.   I need to know what pressure and flow rate is correct for the pump.   Does anyone know this information?Thanks for your help!
Reply:I have a Miller "Radiator 1" for one of my TIG welders.The manual shows the pump for it runs at 1.21 gpm @40 psi and 1725 RPM.Hope that helps.- Paulhttp://all-a-cart.comWelding Cart Kits and accessories
Reply:An ordinary condensate pump, garden fountain pump, fish tank pump, etc, will not produce enough pressure for torch cooling.  Most commercial torch coolers use a Procon brand carbonator pump which is a positive displacement pump that should be properly matched to your system.  You can buy Procon pumps from Grainger's industrial equipment sales (www.grainger.com).The pressure and flow numbers given by ZTFab are in agreement with what I've heard elsewhere in the forum and I would trust them.  Of course, you are always best off contacting the torch manufacturer for flow/pressure requirements.I posted in another thread here a reference to a Little Giant "high pressure" centrifugal pump being offered by C & H Sales, an excellent surplus store in Pasadena, for a very reasonable price.  (CANDHSALES.COM)  Catalog price was about $15 or $25, I don't remember exactly.  They are brand new in the box.  They are slightly deficient in pressure, but should be fine if you are not pushing your torch to its limit.  They also have 115 VAC brush motors with non-replaceable brushes and rated life of about 800 hours, I think.  Plenty for typical hobbiest's usage for many years.awright
Reply:Paul, thanks for the info on the pump specs!Awright, thanks for the suggestions.  Are any of the pumps you mentioned submersible, or do they run off a seperate electric motor?Any more ideas or info is welcome!
Reply:See the thread, "WeldingWeb™ - Professional Welding Forum > WeldingWeb Disciplines > Machines, Tools & Cutting Methods Water coolers for welders" for my suggestion of a new pump available cheaply on surplus that provides higher pressure than a fountain pump.This is NOT a submursible pump.  There are links to the source, the manufacturer, and the data sheets in the thread cited above.awright
