Yes three lines black hose has gas usually 100% Argon with right hand threads
Second line is red has the conductor inside of it with left hand threads for water
Third line blue is return line also left hand threads for water.

Dont run the torch without the pump on. Even if there is water in your lines. You wont have very many seconds to weld without a pump running. Most Lincoln TIG rigs have a switched AC socket in the back to hook a water cooler into if it doesnt have one already built in.
