can kill.

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.

Above diagram shows electrode connected positive. To change polarity, turn power off, reverse the electrode and work leads at the power source and position the switch on power source to proper polarity.

For optimum performance with the LN-9 GMA, DC-600’s with codes 8288 and above are preferred.

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

N.C. 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. (This extended #21 lead connection replaces the need to employ the remote work lead accessory on LN-9’s which have a direct work lead jack.)

N.D. Tape up bolted connection.

N.E. Connect the LN-9 GMA control cable ground lead to the frame terminal marked near the power source terminal strip. The power source must be properly grounded.

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

White jumper on voltage board to pin “S”.

Blue jumper on voltage board (Later units only) or on start board (Earlier units) to pin “B”.

N.H. For DC-600 Codes below 8200 connect a jumper from “N” to “P” on LN-9 GMA only. There is no NPS terminal strip on codes above 8200.
