Assembly of Precision TIG

INPUT POWER CONNECTION

Plug the input power cord on the Under-Cooler cart into the standard bottom 115V NEMA circuit breaker protected receptacle, located on the back of the Precision TIG machine. Using this receptacle is taking advantage of the "cooler as needed" circuit incorporat- ed into the TIG machine and will prolong the life of the cooler. The lower, or bottom receptacle is clearly marked for this application.

If you wish to use the top 115 V NEMA receptacle located on the back of the machine for cooler opera- tion, the cooler will run 100% of the time that the Precision TIG machine is powered "ON".
