CONNECTION OF RANGER 8 TO LN-7 & K240 CONTACTOR KIT
WARNING: Turn the power off when making connections.
N.A. Use power source polarity switch to set for desired elec-
trode polarity. Position the output selector switch on the
power source to the CV position.
N.B. 3 conductor #16 power cord physically suitable for the
installation and plug rated at 115 volts 15 amperes AC.
N.C. Plug into 115 volt AC receptacle on welder control panel or
other 115 volt AC supply rated at a minimum of 500 volt-
amperes.
N.D. Leads #21 and GND do not appear on LN-7’s with codes
below 7026.
N.E. Welding cables must be of proper capacity for the current
and duty cycle of immediate and future applications.
N.F. If LN-7 is equipped with a meter kit, extend lead #21 using
#14 or larger insulated wire physically suitable for the

installation. An S16586-”length” remote voltage sensing
work lead may be ordered for this purpose. Connect it
directly to the work piece independent of the welding work
cable. For convenience, this extended #21 lead should be
taped to the welding work lead.
N.G. Tape up bolted connection where lead #21 is extended.
N.H. Idler switch on power source must be in high idle position.
N.J. If an optional remote output control is used, connect it to
this terminal strip or 6 pin Amphenol receptacle. NOTE:
Terminal strip or 6 pin Amphenol receptacle not available
on all power sources.
CAUTION: Any speed up of the engine RPM by changing the
governor setting or over-riding the throttle linkage will
cause an increase in the AC auxiliary voltage. If this volt-
age goes above 140 volts, the LN-7 control circuit will be
damaged. The engine governor setting is pre-set at the fac-
tory - do not adjust above RPM specifications listed in
engine welder operating manual.
