CONNECTION DIAGRAM — LN-7 WIRE FEEDER TO ENGINE WELDERS WITH 115 VOLT AC AUXILIARY POWER, CV ADAPTER AND K240 CONTACTOR KIT

S17525

7-15-83

N.A.	Connection shown for negative polarity. For positive polarity, reverse cables connected to output terminals.
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 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 on 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-[ ] remote voltage sensing work lead is available for this purpose. Connect it directly to the work piece keeping it electrically
	separate from the welding work lead circuit and connection. For convenience, this extended #21 lead should be taped to the welding
	work lead.
N.G.	Tape up bolted connection.

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 voltage goes above 140 volts, the LN-7 control circuit will be damaged. The engine governor set- ting is pre-set at the factory — do not adjust above RPM specifications listed in engine welder operating manual.
