hook up your regulator to your tank, the hose to back of welder and your good to go. You will have to set the pressure of the regulator to suite your welding needs. some run 20lbs some use 30lbs I,ve seen guys run as much as they can. sometimes it depends on which gun you have and how clean your steel is that your using. don,t waste your gas if your welding outside because the wind will blow it all away from your work. use flux core if welding outside..
