Blowing TIG hoses

[cruizer]

Well, the idea is to cool the head first and arc cable second. If you try to cool the arc cable first, the water has to sit there get super heated before it gets to the torch head due the resistance of the water entering the cable with the current carrying cable. Where as if the cables are connected right, the return pressure is at the torch head.

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?

Think I've got it figured out, flushed the whole system multiple times. Lots of algae and flakes of crusty hose fittings that plug into the top of the reseviour. Everything seems to be flowing normally now. Dave @ Miller tech was a big help.

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

No worries!

Anyone have experience with using a 'braided rubber' power lead? I think I've got my flow issues worked out, but I'm still running pretty high heat (310A) and don't want to buy anymore vinyl hoses. Seems the braided rubber may be a bit tougher... or is there something better?

Also, the clear housing for the coolant strainer recently turned milky white. I'm at a loss...? Anyone? Only thing I changed was going from Low-Conductive coolant to Distilled water. Weird.

Thanks for everyones help.

I use the rubber hoses with the braided sheath. I love them and is worth running because of the flexibility. But beware, the braided sheath breaks down right where they come out of the torch handle from rubbing. I beef them up with fray-check or shoe-goo.

Nice, thanks. Any high-heat resistant properties to the rubber hose as opposesd to the vinyl?

It's been so long, I really can't answer that.
