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".
