DC CONSTANT VOLTAGE POWER

SOURCES

The following welding system power sources are avail- able for use with all LN-9 GMA models:

The Idealarc® DC-250, DC-400, CV-400, CV-500 and, DC-600 are recommended for use with any LN-9 GMA model, as well as the Pulse Power 500, Invertec V300, and DC650 Pro, with the installation of the optional K442-1 Pulse Power Filter Kit.

R3S-400 and R3S-600 may also be used, but are lim- ited due to narrow voltage range on each tap. They are not recommended if input voltage varies.
