Above diagram shows electrode connected positive. To change polarity, turn power off, reverse the electrode and work leads at the
power source and properly set the feeder polarity switch.

N.A. Welding cables must be of proper capacity for the current and duty cycle of immediate and future applications.

N.B. Extend lead #21 using 14 AWG or larger insulated wire physically suitable for the installation. An S16586-[ ] remote voltage sens-

ing 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.C. Tape up bolted connection.

N.D. Connect the control cable ground lead to the frame terminal marked near the power source terminal strip. The power source

grounding terminal (marked and located near the power source input power connections) must be properly connected to elec-
trical ground per the power source Operating Manual.

N.E. Connect control leads t terminal strip as follows:

LN-9:

A to 75

B to 77

C to 78

N.F. The LN-9 voltage control jumpers must be connected as follows:

White jumper on voltage board to pin “S”.
Blue jumper on voltage board is not connected to any pin. (Secure loose jumper clear of any possible interference.)

NOTE: For proper pulse welding operating with LN-9:

1. The LN-9 must have an L6084-3 (or higher superseding part number) voltage board installed. (Standard above code 9100.)

2. The Pulse Power Filter board must be installed and connected in the LN-9 per instructions provided with the kit.

3. The pulse current sensor assembly (with looped copper energizer) must be installed. (Standard above code 9100.) Feeder

conversion kits are available for all LN-9 model codes (below 9100 and above 9100).

WARNING

• Turn off input power to the welding

power source using the disconnect
switch at the fuse box before connect-
ing the wire feeder

• Only qualified persons should install,

use or service this machine.

ELECTRIC SHOCK

can kill.
