20F torch plumbed wrong?
I just received a 325ext with a #9 and #20 torch. I have the #9 in use but while checking out the water cooled torch I blew through the lines coming out of it, one blue, one black (not sure which is return or feed, if it matters). I think something is up since blowing through the blue hose sends air out of the torch head. Blowing through the black hose blows air out of the jacketed hose the would connect to the GAS port on the machine. I'm afraid to even hook it up, is this wrong?
