PRODUCT PURPOSE

The CV Adapter can be connected to certain variable voltage water-cooled engine welders to provide con- stant voltage output recommended for welding .068 and .072 NR-232, .068 and 5/64 NR-211, 5/64 NS-3M, Innershield electrodes within the current rating of the machine used. The unit can also be used for some other open arc processes depending on the application and process to be used. With the CV Adapter installed, the welder can be easily set to operate in either the CV mode or the standard VV mode.

Three models have been available, one for SA-200 and SA- 250 welders, one for SAE-300, SAE-400 and SAE-400 WELD’N AIR engine welders and one for SAE-350 engine welders.

The LN-15, LN-22 and LN-25 wire feeder is recom- mended for Innershield welding with the CV Adapter because no terminal strip is provided for wire feeder control wires, and there is no output contactor. (The K279 contactor voltage control option cannot be used with the LN-15,LN-22, OR LN-25 in this application.) An LN-7 can be used with an SA-250, SAE-350, SAE- 300, SAE-400 or SAE-400 WELD’N AIR that has AC auxiliary power provided a K240 Contactor Kit is con- nected between the LN-7 and the power source.

The voltage control range of the CV Adapter is 15 to 35 volts at the welder current rating. The table gives a summary of CV outputs when the Adapter is connect- ed.
