ahh jk ..... if distilled water will do everything that the welding coolant will do except keep it from freezing then ill prob just do that either that or if i get a job that pays a little bit then ill buy some coolant i know i dont have 5 grand tide up into my setup but if it will make everything (cooler and tig torch and lines) last longer and perform better then i dont mind springin for the welding coolant. thanx to all for the advice and insight.
