OUTPUT CONNECTIONS

Output Studs

The output leads are connected to the output termi- nals. The output terminals are located on the lower case front and labeled “+” and “-”. There are 1000 amp rated “+” terminals on the right side, one 500 amp rated “+” terminal near the center and “-” termi- nals on the left side. They are fully recessed to mini- mize the possibility of accidental contact by an object or a person. Strain relief is provided by the oval holes in the base. The leads are run through these oval holes before they are connected to the output termi- nals.

The 1000 amp output connections provide the full rated output range of the machine. See Table1 for recommended DC-1000 cable sizes for combined lengths of electrode and work cables.

The 500 amp output connections provide enhanced lower current arc characteristics, especially for sub- merged arc and GMAW procedures below 450 amps.

Auxiliary Power

This machine supplies the 115 volt, AC power needed for operating wire feeding equipment. The power is available from terminals #31 and #32 on the terminal strip. An 8 amp slow blow fuse on the machine control panel protects the auxiliary power from excessive overloads. The circuit has a 1000 volt-ampere rating.

Control Cable Connection

Terminal strips with screw connections are located behind the hinged door on the front of the power source to make all the control cable connections for operating wire feeding equipment. See the appropri- ate connection diagram for exact instructions covering the wire feeder being used.

With the DC-1000 turned off, the control cable from the automatic wire feeding equipment is connected to the terminal strip. A strain relief box connector is pro- vided for access into the terminal strip section. A chassis grounding screw is also provided below the

terminal strip marked with the symbol for connect- ing the wire feeding equipment grounding wire. See the appropriate connection diagram for the exact instructions for the wire feeder being used. A spare hole is provided for an additional box connector if required.

Connecting for Air Carbon Arc:

a.Turn off all power.

b.Disconnect all wire feed unit control, electrode and work leads.

c.Connect a jumper from 2-4 on terminal strip.

d.Place mode switch in the CV(I) position.

With the DC-1000 connected for air carbon arc weld- ing, the output terminals will be energized at all times.
