GENERAL DESCRIPTION

The DC-655 is an energy efficient constant voltage DC power source that produces outstanding arc characteristics for multi- ple CV or CC welding processes

Four models are available:

Domestic - all 60 Hertz models except 230/460/575v.

NEMA Class 1 rated

Canadian - 230/460/575v 60 Hertz NEMA Class 1 rated

European - 50/60 Hertz models “CE” qualified and rated for IEC 974-1

Export - 50/60 Hertz models NEMA Class 1 rated

RECOMMENDED PROCESSES AND EQUIPMENT

The DC-655 is designed for CV or CC processes.

CV processes include: GMAW (MIG) and FCAW (flux- cored) welding, plus the capability of CV submerged arc welding and air carbon arc gouging. It produces outstanding welding performance with a single range full output control knob.

CCprocesses include stick welding, CC submerged arc and superior air carbon arc gouging with up to 3/8” (10 mm) diameter carbons. The same single range full output control knob is used and paralleling capability is provided.

The DC-655 is recommended for use with Lincoln’s DH-10 or LN-10 as well as the LN-7*, LN-7 GMA*,LN- 15, LN-742, LN-8*, LN-9*, LN-9 GMA*, LN-23P and LN-25 semiautomatic wire feeders. It is also recom- mended for use with the NA-3, NA-5 and NA-5R auto- matic feeders. “Cold starting” for sub-arc or across arc “touch-sensing” can be used.

*The 14-pin MS receptacle on the European mod- els does not provide 115 VAC for these feeders; 115 VAC must be obtained from terminal strip.

Two DC-655’s may be paralleled in a “master” and “slave” interconnection using the K1611-1 Paralleling kit.
