HIGH FREQUENCY GENERATORS FOR TIG APPLICATIONS

The K799 Hi-Freq Unit and the K930-1 or –2 TIG Module can be used with the Commander 300. The machine is equipped with the required RF bypass cir- cuitry for the connection of high frequency generating equipment. The high frequency bypass network sup- plied with the K799 Hi-Freq Unit does NOT need to be installed into the Commander 300.

The Commander 300 and any high frequency generat- ing equipment must be properly grounded. See the K799 Hi-Freq Unit and the K930-1 or –2 TIG Module operating manuals for complete instructions on instal- lation, operation, and maintenance.

REMOTE CONTROL

The Commander 300 is equipped with a 6-pin and a 14-pin connector. The 6-pin connector is for connect- ing the K857 or K857-1 Remote Control (optional) or the K870 hand Amptrol or K812 foot Amptrol (TIG applications).

The 14-pin connector is used to connect a wire feeder or K930-1 or –2 TIG Module control cable. When remote output control is used, the output control tog- gle switch must be set at REMOTE.

NOTE: When using the 14-pin connector, do NOT con- nect anything to the 6-pin connector if the wire feeder has a built-in power source output control.

Also see the Accessories section of this manual for more information on wire feeder connections.

WELDING TERMINALS

The Commander 300 has a toggle switch for selecting “hot” welding terminals (WELDING TERMINALS ALWAYS ON position) or “cold” welding terminals

(WELDING TERMINALS REMOTELY CONTROLLED position).
