Connection of the LN-7 to the Ranger 8
a. Shut the welder off.
b. Connect the LN-7 and the K240 contactor kit per
instructions on the connection diagram S17742
(can be found in the back of this manual).
c. Place the “RANGE” switch to the “WIRE FEED”
position and the “POLARITY” switch to the
desired polarity.
d. Place the “IDLER” switch in the “HIGH” idle
position. The engine idling device may not
function when welding in the “WIRE FEED” mode.
e. Adjust wire feed speed at the LN-7 and adjust the
welding voltage with the output “CONTROL” at
the welder.
NOTE: If the output “CONTROL” is set below “3” the
K240 contactor may not pull in.
Connection of TIG Module (K930-1)
to the Ranger 8
The 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 8, a bypass capacitor (Order Kit
T12246) must be installed in the Ranger 8.
OPERATING
INSTRUCTIONS
Additional Safety Precautions
Always operate the welder with the roof and case
sides in place as this provides maximum protection
from moving parts and assures proper cooling air flow.
Do not tamper with the carburetor settings or the fuel
hose from the regulator to the carburetor. The engine
has been pre-set for optimum performance. Changes
in the carburetor settings or fuel hose length can
result in reduced performance and excessive carbon
monoxide emmisions.
Read and understand all Safety Precautions before
operating this machine. Always follow these and any
other safety procedures included in this manual and in
the Engine Owner’s Manual.
