Im trying to build a tig cooler for my TA300.
I was thinking of using one of these in the cooling circuit:
I was planning on using a 5 gallon SS Cornelius keg from homebewing (I have plenty) as a tank, along with a Procon pump.
Now the questions:
For cooling, do I need a heat exchanger, or for a hobbyist, will I get by with the keg filled with 5 gallons of coolant alone? If it really ever gets really hot, I can dump it and fill up with fresh water. My town water is chlorinated but close to distilled with less than 15 ppm of any salts. Would you consider welding some SS stock to the keg to act as cooling fins?
My reservation on the exchanger is the possible intoduction of aluminum into the cooling circuit. I understand that their may be some long term electrical destruction of the Aluminun with the copper in the torch.
Do the Procon pumps have an integral pressure regulator that is adjustable, or is it only on certain models?
Where do I find the female fittings for the torch water lines? I will be using a CK 230 torch.
Thanks in advance and sorry for the long post.
