RETURN TO MAIN MENU IM860 IDEALARC ® CV-305 February, 2006 For use with machine Code Numbers 11177, 11178 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 thoughtful operation on your part. DO NOT INSTALL, OPERATE OR REPAIR THIS EQUIPMENT WITHOUT READING THIS MANUAL AND THE SAFETY PRECAUTIONS CONTAINED THROUGHOUT.
i i SAFETY WARNING CALIFORNIA PROPOSITION 65 WARNINGS Diesel engine exhaust and some of its constituents are known to the State of California to cause cancer, birth defects, and other reproductive harm. The Above For Diesel Engines The engine exhaust from this product contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm. The Above For Gasoline Engines ARC WELDING CAN BE HAZARDOUS.
ii ii SAFETY ELECTRIC SHOCK can kill. 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.
iii iii SAFETY WELDING SPARKS can cause fire or explosion. 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 and hot materials from welding can easily go through small cracks and openings to adjacent areas. Avoid welding near hydraulic lines. Have a fire extinguisher readily available. 6.b.

A-2 A-2 INSTALLATION Read entire installation section before starting installation. INPUT CONNECTIONS SAFETY PRECAUTIONS Be sure the voltage, phase, and frequency of the input power is as specified on the welder nameplate. WARNING ELECTRIC SHOCK can kill. • Only qualified personnel should perform this installation. • Turn the input power OFF at the disconnect switch or fuse box before working on this equipment.
A-3 A-3 INSTALLATION LN-742 to CV-305 FIELD INSTALLED OPTIONS a) Turn the CV-305 Power switch to the "OFF" position. For installation of compatible field installed options (see the ACCESSORIES section of this manual and refer to the instructions included with those options. b) Connect the LN-742 control cable to the wire feeder receptacle on the CV-305. REQUIRED EQUIPMENT-CONTROL CABLE CONNECTIONS Follow the instructions below which are appropriate for the wire feeder that will be used.
A-4 INSTALLATION PARALLELING The CV-305 is not designed to be paralleled with itself or any other power source. CONNECTION OF AUXILIARY EQUIPMENT TO THE WIRE FEEDER RECEPTACLE Occasionally, it may be necessary to make connection to the circuits present in the 14-pin wire feeder receptacle. These circuits, such as the auxiliary voltage, contactor, and remote control circuits, may be accessed with a K867 Universal Adapter.
B-1 OPERATION OPERATING INSTRUCTIONS Read and understand this entire section before operating the machine. GENERAL WARNINGS SAFETY PRECAUTIONS WARNING ELECTRIC SHOCK can kill. • Do not touch electrically live parts or electrode with skin or wet clothing. • Insulate yourself from work and ground. • Always wear dry insulating gloves. FUMES AND GASES can be dangerous. • Keep your head out of fumes. • Use ventilation or exhaust to remove fumes from breathing zone.
B-2 B-2 OPERATION GRAPHIC SYMBOLS THAT APPEAR ON THIS MACHINE OR IN THIS MANUAL THERMAL PROTECTION INDICATOR LIGHT OFF ON CIRCUIT BREAKER AC POWER CLOCKWISE ROTATION INCREASES VOLTAGE LOCAL OUTPUT VOLTAGE CONTROL REMOTE OUTPUT VOLTAGE CONTROL WARNING INDICATES WARNING INFORMATION LOCATED ON RIGHT CASE SIDE CV-305
B-3 OPERATION B-3 • 115 VAC, 5 amp auxiliary power available for the wire feeder; circuit breaker protected. CAUTION When using a CV-305 power source with wire feeders, there will be a small spark if the electrode contacts the work or ground within several seconds after releasing the trigger. When used with some wire feeders with the electrical trigger interlock in the ON position, the arc might restart if the electrode touches the work or ground during these several seconds.
B-4 B-4 OPERATION CONTROLS AND OUTPUT SETTINGS All operator controls and adjustments are located on the case front of the CV-305. Refer to Figures B.1. FIGURE B.1 - CONTROL AND OUTPUT PANEL 5 3 4 8 1 7 6 2 9 10 13 11 12 1. POWER SWITCH A two-position toggle switch.Controls the input power to the CV-305. 2.

B-5 OPERATION 9. WIRE FEEDER VOLTMETER SWITCH B-5 12. HIGH INDUCTANCE NEGATIVE OUTPUT CONNECTION. This switch selects the polarity of the wire feeder voltmeter, if so equipped. When welding electrode positive (MIG, Outershield and some Innershield processes) set the switch to "+". Output connector is a Magnum Twist-Mate™, receptacle. Insert a mating Twist-Mate™ plug, and twist clockwise to secure.
B-6 B-6 OPERATION STARTING THE MACHINE AUXILIARY POWER The power switch at the extreme right side of the control panel energizes the CV-305. 42 volt AC auxiliary power, as required for some wire feeders, is available through the wire feeder receptacle. A 10 amp circuit breaker protects the 42 volt circuit from overloads. ADJUSTING THE OUTPUT VOLTAGE USING THE DIGITAL METER The digital meters in the CV-305 incorporate a voltage preset function.
