I'm considering a PowerTIG 250EX.

I've been in e-mail contact with the welder where I used to work asking for his opinion on TIG welders.

He noticed that the 250EX comes with a water cooled torch yet the water cooler is an option.

As he put it:

One thing I did notice about the Everlast is the torch listed on the site says it's water cooled but the standard package does not have a water cooler included (it's in the optional column). This is a no-no, never run a water cooled torch without the coolant running, ever. Make sure you either get an air cooled torch or that you add the water cooler to your list of things to buy.
Why would Everlast include a water cooled torch in a kit that does not include the cooler?
