So I finally got around to finishing a cooler for my tig..... all together it only took around 9.5 hrs. considering all the trips to p/u parts. The total did not exceed $150, I p/u the pump for $40, various radiators from a local junkyard for $40, a 1 gal res/ cooler for 8 bucks, & all the correct fittings for around $55, & maybe $10 in fuel...
