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.
