Arc Welding 101: CV or CC What’s the difference? Direct current (DC) power supplies can be constant voltage (CV) or constant current (CC). CV equipment, typically used for semiautomatic and wire fed processes like gas metal arc welding (GMAW) or flux cored arc welding (FCAW), provides a consistent preset voltage. Presetting the weld voltage on a CV power supply will maintain a constant arc ... Constant Voltage, Constant Current Battery Charging Constant voltage allows the full current of the charger to flow into the battery until the power supply reaches its pre set voltage. The current will then taper down to a minimum value once that voltage level is reached. The battery can be left connected to the charger until ready for use and will remain at that “float voltage”, trickle charging to compensate for normal battery self discharge. How do lipo chargers know when to switch from CC to CV ... It's all in the names. You have a two stage charge (CC & CV) with a target voltage. It charges via CC till it reaches the target voltage, then it has to switch to CV or it would go over the target voltage. LTC4013 CC CV 10s4p Li ion charger selectable charging ...
