Remote Output Control
The Ranger 9 has a 6-pin and a 14-pin Amphenol
connector. These connectors are located above the
output studs. The 6-pin connector is intended to be
used with the optional K857 Remote Output Control or
in the case of TIG welding applications, with the Foot
or Hand Amptrol. The 14-pin connector is used to
connect a wire feeder control cable. If the wire feeder
has a built-in power source output control, do not
connect a remote output control to the 6-pin
connector. When remote output control is used, the
output control toggle switch is to be set at “CONTROL
REMOTE”.
High Frequency Generator for TIG
welding applications
The K930-1 TIG Module is an accessory that provides
high frequency and shielding gas control for AC and
DC GTAW (TIG) welding. See IM528 supplied with
the TIG Module for installation instructions.
Note: The TIG Module does not require the use of a
high frequency bypass capacitor. If any other high
frequency accessory is used with the Ranger 9, a
bypass capacitor (Order Kit T12246) must be installed
in the Ranger 9.
