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 reverse the “control switch” at the power source, and the “polarity switch” on the LN-9 GMA.

Connect the control cable ground lead to the frame terminal marked	near the power source terminal strip or to an unpainted frame
screw. The power source must be grounded properly.

N.A. On earlier R3S-400, -600 & 800 machines, #67 & #1 terminals were also on the terminal strip.

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 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. (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.E. Upper terminal strip (#75, #76 & #77) may not appear on older R3S machines, and therefore is not compatible for use since there will be no adjustment of voltage by the LN-9 GMA.

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

White jumper on voltage board;

To pin “F” for open arc process or

To pin “S” for submerged arc process.

Blue jumper on voltage board (later units only), or on start board (earlier units), to pin “A”.
