IDEALARC CV-305 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 thought- ful operation on your part.
351040, Miami, Florida 33135 or CSA Standard W117.2-1974. A Free copy of “Arc Welding Safety” booklet E205 is available from the Lincoln Electric Company, 22801 St. Clair Avenue, Cleveland, Ohio 44117-1199. BE SURE THAT ALL INSTALLATION, OPERATION, MAINTENANCE AND REPAIR PROCEDURES ARE PERFORMED ONLY BY QUALIFIED INDIVIDUALS.
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.

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.

The code number is especially important when identifying the correct replacement parts. - Register your machine with Lincoln Electric either via fax or over the Internet. • For faxing: Complete the form on the back of the warranty statement included in the literature packet accompanying this machine and fax the form per the instructions printed on it.
• Do not touch electrically hot parts. • Always connect the Idealarc CV-305 grounding terminal (located on the welder base near the reconnect panel) to a good electrical earth ground.
FIELD INSTALLED OPTIONS For installation of compatible field installed options (see the ACCESSORIES section of this manual and refer to the instructions included with those options. REQUIRED EQUIPMENT-CONTROL CABLE CONNECTIONS Follow the instructions below which are appropriate for the wire feeder that will be used. LF-72 to CV-305 a) Turn the CV-305 Power switch to the "OFF"...
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 recep- tacle.
OPERATING INSTRUCTIONS Read and understand this entire section before oper- ating the machine. GENERAL WARNINGS SAFETY PRECAUTIONS Observe additional Safety Guidelines detailed throughout this manual.

CAUTION When using a CV-305 power source with wire feed- ers, there will be a small spark if the electrode con- tacts 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.
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 1. POWER SWITCH A two-position toggle switch.Controls the input power to the CV-305. 2.

9. WIRE FEEDER VOLTMETER SWITCH 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 "+". When welding electrode negative (most Innershield electrodes) set the switch to "-". This switch has no effect on the welding polarity.
CV-305 auxiliary power for that equip- ment. ___________________________________________ OVERLOAD PROTECTION This welder has thermostatic protection from exces- sive duty cycles, overloads, loss of cooling, and high ambient temperatures. When the welder is subjected to an overload or loss of cooling, a thermostat will open.
FACTORY INSTALLED OPTIONS/ACCESSORIES There are no factory installed options/accessories on the CV-305. FIELD INSTALLED OPTIONS REMOTE VOLTAGE CONTROL (K857) The K857 consists of a control box with 25 feet (7.6 m) of four conductor cable. Installation of a K857 Remote Voltage Control in the CV-305 requires a K864 Remote Control Adapter.
1. The fan motor has sealed bearings which require no service. 2. In extremely dusty locations, dirt may clog the air channels causing the welder to run hot with prema- ture tripping of thermal protection. Blow out the welder with low pressure air at regular intervals to eliminate excessive dirt and dust build-up on inter- nal parts.
