    Default Blowing TIG hoses

    Anyone have issues with their TIG powerlead blowing holes near the machine, spewing coolant everywhere? Just breached my fourth hose in two weeks, no idea whats going on. Cleaned the coolant strainer, going to pull the whole reseviour/ radiator today to clean, troubleshoot. Been running pretty high amperage lately but never had a problem with it before. Syncrowave 250DX/CK200/CK300
    Not stoked! Any help will be much appreciated, thanks.

    Obviously you have a blockage or motor stoppage.

    Check the flow coming out of the torch, and consider putting Ck fuseblocks on your power cable in case of motor stoppage.

    My guess is your motor is overheating and the thermal overload switch is tripping leaving an air pocket in your power cable because coolant is not flowing.

    That or you have them hooked up backwards which is more likely. Both waters have the same thread, though one is high pressure and one is drain. If you get em backwards. the hoses will blow...

    Hoses are hooked up correctly, one is reversed thread. I've been running this machine for over two years now and just started seeing this issue. Weird.

    Oh, whoops. I see what you mean. Yes both are threaded the same, and hooked up correctly... thanks.

    How would you suggest I check the flow, unplug the return and turn the machine on? Not sure..
    And how can I confirm the motor is over heating?
    Thanks.

    You could unscrew the big power cable nut at the machine, and turn on.

    The only way to confirm if the pump motor is overheating is to watch for it. Are there fan louvers to tape strands of paper over?

    I always wondered about that.

    Why would they blow?

    I could not see why it would blow if it was backwards flow is flow right ? As long as it don't stop ? Sorry to jack your thread

    Unhook the return at the cooler and turn it on with the return held over the refill on the cooler. If its slow something is restricting flow. I've had coolmate 4's oxidize the copper heat sinc tubing inside and flake off which reduced flow considerably, have also had algae build up do the same thing
