Read this entire installation section befor e you start installation. SAFETY PRECA UTIONS ELECTRIC SHOCK can kill. • Do not touch electrically live par ts such as output ter minals or inter nal wiring. • Insulate yourself from the work and ground.
GROUND CONNECTION The frame of the welder m ust be grounded. An ear th grounding lead must be connected to the g rounding terminal, mar ked on the input bo x floor with the symbol (See Figure A.2 ). Ref er to T echnical Specifi- cations page f or proper ground wire size.
Hav e a qualified electrician connect the input power leads to the L1, L2, and L3 terminals of the input con- tactor . F ollow all national and local electrical codes. Use a three-phase line. Install the reconnect panel jumper links (see Figure A.3) f or the proper input volt- age.
RECONNECT PR OCEDURE Multiple input voltage w elders are shipped from the f ac- tor y connected f or the highest voltage listed on the machine's rating plate . Before installing the welder , be sure the reconnect panel is connected f or the proper v oltage.

GENERAL DESCRIPTION The IDEALARC CV -400 is an SCR controlled three- phase input, DC output power source f or welding. It uses a single range potentiometer control.
WELDING CAP ABILITY The CV -400 has the f ollowing duty cycle ratings. If the duty cycle is e xceeded, a thermal protector will shut off the machine output until it cools to nor mal operating temperature. The amber ther mal protection indicator light will tur n on until the machine cools.
1. PO WER SOURCE PILO T LIGHT : This light indi- cates that the pow er source input contactor is ener- gized (closed). This also means that the main power transf or mer and all auxiliar y control transf or mers are energized. 2. ON/OFF PO WER T OGGLE SWITCH: Energizes or deengergizes the input contactor .
