Reply:You need inert gas hose in whatever inside diameter you have on your machine. Any industrial hose supply or welding supply outlet will have it. Sent from my iPad using Tapatalk:

Reply:So this looks like just normal air compressor hose ? So this would work correct ? I cant find anything welding specific.https://tinyurl.com/4rurredk

What you linked just says it's polyurethane which is an entire class of plastic. Who knows what sort of properties it has. Also the company selling it is based in China so you really won't know what you're getting. The fact that your machine already had what appears to be polyurethane tubing that broke is probably a sign it's not suitable for a welding machine. You're looking for something like this:https://www.ckworldwide.com/products...orced-gas-hose  - which is a nylon tubingor https://www.airgas.com/product/Gas-E.../p/RAD64003359  - which is a EPDM rubberBoth are specifically for welding, but the EPDM Rubber one says MIG so I'd probably look for that material in a hose that fits your machine.You'll want to figure out what kind of fittings your machine has, and what diameter the tubing is then chances are you can find a premade hose with new fittings already on it. You can also buy EPDM Rubber tubing in the right diameters and install the fittings yourself if you want to go that route. If you do that make sure the tubing will handle the pressure.I'd imagine you could find the tubing here if you want: https://www.mcmaster.com/hose/materi...r/air-hose-11/
Reply:yes it has no fittings as danielplace said.Just a piece of hose with 2 ear clamps.Just wasn't sure what spec it needed to be - eg how much pressure etc

If it goes from solenoid to the mig feeder/torch there is very little pressure on that hose because it is only feeding the wide open torch at the end it doesn't back up high pressure at all.

Reply:This thread caught my eye as a Tweco 211i owner. I'm surprised (and disappointed) to see that line burst post-solenoid especially as these machines aren't that old and it likely sees single-digit psi numbers. Any chance you have an obstruction downstream?
