WARNING

ELECTRIC SHOCK can kill.

•Only qualified personnel should per- form this maintenance.

•Turn the input power OFF at the dis- connect switch or fuse box before working on this equipment.

•Do not touch electrically hot parts.

•Insulate yourself from work and ground.

NOTE: When using a CV-400 with wire feeders, there may be a small spark if the electrode contacts the work or ground within a few seconds after releasing the trig- ger. With some wire feeders, when the electrical inter- lock is in the ON position the arc can restart if the elec- trode touches the work or ground during these few sec- onds. Refer to K828-1 capacitor discharge circuit ear- lier in this section.

The following descriptions show how to connect the wire feeders using the terminal strip.

• Always wear dry insulating gloves.

Auxiliary power for wire feeder operation is available at both a 14-pin amphenol and at terminal strips with screw-type connections located behind the hinged con- trol panel on the front of the machine. The 14-pin amphenol can provide both 115 VAC (pins A and J) and 42 VAC (pins I and K). The terminal strip provides only 115 VAC (terminals 31 and 32). The two circuits are iso- lated, and each is protected by a 10A circuit breaker.

AUTOMATIC WIRE FEEDERS

CONNECTING THE NA-3 TO THE IDEALARC CV-400

1.Set the CV-400 POWER toggle switch to the OFF (0) position.

2.Disconnect main AC input power to the CV-400.

3.Connect the wire feeder control cable leads to the CV-400 terminal strip as shown in Figure C.2.

4.Connect the wire feeder control cable ground lead to

the frame terminal marked .

NOTE: The CV-400 must be properly grounded.
