Lincoln Electric IM672 RED-D-ARC ZR-8 - Manual (Page 17)

– 16 –
Connection of the LN-7 to the ZR-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 K930-1 TIG Module to the
ZR-8.
The TIG Module is an accessory that provides high
freqency 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. However, if the ZR-
8 is used with any other high frequency equipment,
the bypass capacitor must be installed - order kit
T12246.
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.
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.
