Switch from water cooled to air cooled hose and torch on a TIG 250 EX.

I have a TIG 250 EX welder. I would like to replace the water cooled hose and torch for an air cooled 17 hose and handle. Does the one offered on the Everlast site - Nova 17 flex-neck torch 12.5', series 35 DINSE, $129 SKU:NVA-17F-125-UF-35QD - fit with the 250 EX welder? Would I need anything else to make the switch? Also, can I replace the Nova torch with a CK Worldwide 17 flex head torch? Thanks in advance.

Our torches are ready to fit. You need the 35 dinse type which you've already selected.
