Lincoln Electric IM669 RED-D-ARC DC-600 - Manual (Page 16)

GENERAL DESCRIPTION
The DC-600 is an SCR controlled three phase welding
and cutting power source. It uses a single range
potentiometer to control:
• Submerged Arc Semi-Automatic or Automatic
Welding
• Open Arc Semi-Automatic or Automatic Welding
• Stick Welding
• Air/Carbon Arc Cutting (Carbon Rod Sizes up to
3/8” Diameter)
The DC-600 has a three-position Welding Mode
Switch to enable the user to operate in one of three
modes:
• Constant Current (CC) Stick (also used for AAC)
• Constant Voltage (CV) Submerged Arc
• Constant Voltage (CV) Innershield (also used for
GMAW)
The optional Multi-Process Switch allows the user to
switch between semi-automatic or automatic welding
and stick welding or air/carbon arc cutting without dis-
connecting the wire feeder equipment control, elec-
trode,and work leads.
RECOMMENDED PROCESSES AND
EQUIPMENT
The DC-600 is designed for GMAW (MIG), FCAW,
and submerged arc (SAW) within the capacity of the
machine. It can also be used for stick welding
(SMAW) and for air carbon arc (AAC) cutting with car-
bon rods up to 3/8" diameter.
The DC-600 is provided with a three position mode
switch that selects CV Innershield, CV Submerged
Arc, or CC Stick.
The DC-600 can be easily connected to wire feeding
equipment, including:
• Semi-automatic wire feeders LN-7, LN-7 GMA,
LN-742, LN-8, LN-9, LN-9 GMA, LN-10, DH-10
LN-15, LN-23P, and LN-25.
• Automatic wire feeders NA-3, NA-5, and NA-5R.
• Tractors LT-7 and LT-56

ground.
• Always wear dry insulating
gloves.
• Do not use AC welder if your clothing, gloves or
work area is damp or if working on, under or
inside work piece.
Use the following equipment:
- Semiautomatic DC constant voltage
(wire) welder.
- DC manual (stick) welder.
- AC welder with reduced voltage
control.
• Do not operate with panels removed.
• Disconnect input power before servicing.
