Safety Depends on You

Lincoln arc welding and cutting

equipment is designed and built

with safety in mind. However, your

overall safety can be increased by

proper installation ... and thought-

ful operation on your part.

And, most

importantly, think before you act

and be careful.

Page 2 351040, Miami, Florida 33135 or CSA Standard W117.2-1974. A Free copy of “Arc Welding Safety” booklet E205 is available from the Lincoln Electric Company, 22801 St. Clair Avenue, Cleveland, Ohio 44117-1199. 1.a. Turn the engine off before troubleshooting and maintenance work unless the maintenance work requires it to be running.
Page 3 3.a. The electrode and work (or ground) circuits are electrically “hot” when the welder is on. Do not touch these “hot” parts with your bare skin or wet clothing. Wear dry, hole-free gloves to insulate hands. 3.b. Insulate yourself from work and ground using dry insulation. Make certain the insulation is large enough to cover your full area of physical contact with work and ground.
Page 4 6.a. Remove fire hazards from the welding area. If this is not possible, cover them to prevent the welding sparks from starting a fire. Remember that welding sparks materials from welding can easily go through small cracks and openings to adjacent areas. Avoid welding near hydraulic lines.

Page 7 Install the welder in a dry location where there is free cir- culation of air in through the louvers in the front and out through the louvers in the back of the case. A location which minimizes the amount of smoke and dirt drawn into the machine reduces the chance of dirt accumulation that can block air passages and cause overheating.
Page 8 e. Optional Remote Control (K775) This control is included as part of the “NL Option”. Connect it to the “NL Option” box per instructions shipped with the option. (Not required with the NA-3, NA-5, LT-7 or LT-56.) It can be purchased separately when the DC-1500 is used for other applications.
Page 9 The output can be controlled either at the wire feeder or the DC-1500. When the NL Option Kit is installed, how- ever, output is controlled only from the K775 Remote Con- trol usually mounted at the wire feeder. To adjust the output from the wire feeder, set the toggle switch on the front of the DC-1500 to “Output Control Remote”.
Page 10 2. Arc striking with DC-1500 mode switch on Cv sub-arc or CV Innershield — There are a number of basic tech- niques for good arc striking that apply to all processes and power sources. It may not be necessary in every application to follow these guidelines, but when striking problems do occur, following the suggestions below should provide trouble-free starting.
Page 11 (See chart below.) 1. Install the NA-5 per the information in the NA-5 op- erating manual (IM-305). Connect the NA-5 to the DC-1500 as described on the connection diagram. 2. Place the DC-1500 mode switch in the proper position according to the process and procedure to be used. 3.
Page 12 (Not Required With NA-3, NA-5, LT-7 or LT-56) The K783 NL option kit (for field installation) is designed to permit use of the NA-2, LAF-3, LT-3 and the LT-3 section of the LT-34 tractor with DC-1500’s assigned code 7687 and above. It provides the necessary DC control power for the operation of the equipment and the necessary circuitry for proper inching, cold starting and arc striking.
Page 13 3. Remove the blue jumper lead connected between #1 on the coil of the main relay and #7 on the coil of the transfer relay. (The main relay is the upper right relay when facing the left end of the control box. The transfer relay is just to the left of the main relay.) 4.
Page 14 Machine has output but trips off immediately. If for any reason you do not understand the test procedures or are unable to perform the tests/repairs safely, contact the Lincoln Electric Service Department for technical troubleshooting assistance before you proceed. Call 216-383-2531 or 1-800-833-9353.

LED L4 indicates when fault protection circuit is being activated. 5. LED L5 indicates a control signal is being supplied to the firing circuit.

Page 18 Above diagram shows electrode connected po- sitive. 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. N.A. On codes above 8234 extend lead 67 and connect it to the electrode cable going to the au- tomatic equipment.
Page 19 Above diagram shows electrode connected positive. To change polarity, turn power source off, reverse the electrode and work leads at the power source and position the switch on power source to proper polarity. Also reverse the leads on the back of the ammeter and voltmeter in the automatic control box.
