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, position the positive - negative switch on power source to correspond to the polarity of the electrode cable connection.

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

N.B. 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 separate from the welding work cable connection to work piece. For convenience, this extended #21 lead should be taped along the welding work cable. (This extended #21 lead connection replaces the need to employ the remote work lead accessory on any LN-9 GMA which has a direct work lead jack).

N.C. Tape up bolted connection.

N.D. 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.E. If using an older automatic control cable with leads #75, #76, #77; connect lead #75 to #75 on terminal strip, connect lead #76 to #74 on terminal strip, connect lead #77 to #73 on terminal strip.

N.F. 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.G. Set the DC-1000 controls as follows:

Set the control switch to “output control remote”. For submerged arc processes, set the mode switch to “C.V. submerged arc”. For open arc processes, set the mode switch to “C.V. Innershield”.

N.H. Alternative 500 amp positive terminal connection provided on DC-1000 models above code 9500 only.
