Tig torch plumbing?

admin

Have a Miller Synchrowave 250 with a Weldcraft WP 20 torch. Have been using the sink to cool it up until now. During that time, I have had the water coming in to the power cable adapter then on through to the power/water hose on the torch with the return dumping back down the sink drain. This has worked fine.I have just finished building my own cooler and have plumbed the lines the same way. Water out from the pump into the power cable adapter with the return from the torch going back to the radiator and then tank. This seems to be the most logical way to me. I have yet to fire it up. My question is, does it matter which way I have the water routed to the torch and why? My 'backwards'way as seemed to work fine for the last two years. Thoughts??Thanks, Watty
Reply:I believe you have it correct, and I think it does matter. a lot of TIG power hoses have an undersized conductor that is cooled by the water. if you run it backwards i suspect there is a chance it could overheat.Miller Multimatic 255
