    Re: Water cooler failure??? bad day....

    I finally remembered to take pictures of the degraded torch lines I mentioned. This torch was marked Radnor, so no way of knowing who made it for Airgas, but it seemed pretty nice. The hoses looked perfect, all the fittings were bright and shiny, and even the outer cover was nice. I flushed the cooler and tank, then filled it with clean water and hooked the blue torch line to the cooler out fitting and left the red line disconnected so I could flush the torch and lines....got almost nothing flowing out. I shut it down, disconnected the torch, connected a 6' line to the output and it was sending water at least 15 feet, so I knew the cooler was fine. I tried blowing compressed air through the torch and very little came through, so I ran my hands along the length of the hoses looking for a blockage, but found the soft spots and noted the rubber cracked around the fittings with the blue line being the worst. I pulled the blue line off at the torch and the degraded rubber was really bad. The soft spots along the lines must have been breaking down the same way. I can only assume this junk plugged up the torch, but I haven't gotten around to cutting it apart to see inside.

    I was pretty shocked that lines looking so nice and new could be disintegrating like these are. I've found the exact same thing with several other torches in the past, and all have been used with automotive anti-freeze. I'm not sure if that's a coincidence or not, but it's enough to make me wonder. Probably not a bad idea to just run your hands along the torch lines once a year to feel for soft spots as that might be a good indicator of problems.

    Thatís really something.

    Looks like some thin wall/internal hose

    My CK lines Are much thicker than that

    They didn't start out that thin, it's just that's how badly they crumbled and fell apart. Other areas of the same lines have a wall thickness is several times thicker and look similar to the CK hose pictures you posted. If you look down into the hose a bit you can see where it gets thicker...sort of a ridge/ledge. I'll try to remember to cut a section a few inches away where the wall thickness is normal.

    It's really crazy...run your fingers along the hose and everything is normal, then you hit a spot where the rubber has disintegrated and the rubber collapses with almost no finger pressure. Near the fittings seems to be the worst, but there are areas randomly along the length of hose where you'll find soft spots. I almost wonder if the soft spots were hanging at the bottom of the loop when coiled up on the machine, or something similar, and the chemicals eating the rubber sunk to the low spot.

    Who made the hoses?

    IMO, you don't have much to worry about. My original cooler from 2013 still works just fine, and my 2nd "demo unit" that I use for my stick welder also works fine.

    I think that a failed cooler will make the torch too hot to hold, not burn up the cable? Can someone explain?

    A March 809 pump is an excellent pump but its 12 volts. I have one on my hydronic heater on the boat and it pumps hot water all day.
    The wire gauge in the water-cooled power cable is much smaller than the power cable in an air cooled torch, without water the power cable can glow in the water cooled torch.

    If I wasn't so.....crazy, I wouldn't try to act normal, and you would be afraid.

    I was thinking about this today and
    First of all, we are using the wrong terminology
    Itís actually not a shear pin itís a key
    That fits into the slot (keyway) on the motor shaft which in turn drives the pump.

    That connection is also isolated by seals so the coolant/water never touches the pin or the shaft.

    Well one of the vendors he must have eaten his Wheaties the morning they put mine together.

    I got the cooler up and running and everything is fine againÖ

    But occasionally I see one single drip on the floor

    Couldnít figure out where
    Finally today I found out itís coming from the dinse connector

    I take it apart
    And the center brass piece is f@ckin cracked!

    HTP America is sending a replacement.

    Luckily I kept the old one also.

    Another thing I noticed is,
    They are now using oetiker clamps instead of the screw on compression type.

    They work great but not user-friendly for the every day Joe.
