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).
