    checking homemade tig torch cooler for leaks

    Temporarily bolted components to plywood to make sure everything works as planned. Ran beads continuously on 1/4" aluminum plates for 20 minutes, only stopping to grab more filler. Flow looked good inside tank (about .25 gpm ). Tank has about 2 gallons of tig coolant in it. Temperature wasn't noticeably Higher. I really like the #20 torch much better than the #26 it replaced.Name:  IMG_0588.jpg

    I must have loosened the retaining nut on the coolant line when replacing the power cable . Had to replace the power cable after I tried using a small circulator pump in a 5 gal bucket of water. Flow wasn't sufficient, and melted cable/hose. The first power cable I replaced it with from american torch tip was very stiff, had to order an original weld-tec, much more pliable. This inspired me to make a proper cooler for my Airco(esab) Heliwelder 250 IV. Runs off the 115v outlet next to the foot pedal connector. I didn't bother putting through the solenoid, or adding a switch. When the machine is on, the cooler is always running. Put connector and hose back together, and ran for another 20 minutes continuous, no leaks this time. Now its time to get the foot pedal sorted out.



    sorry about the orientation of photos, these are from an iPhone(not my usual camera) will try to figure it out for next time.

    Generally - if you shoot the photo while holding your device
    Horizontally - it will post Vertically without a due . . .



    Everything you have done 'is do it yourself' straight forward -
    My interest - is your technique/success in securing the tubes
