The Master Power Supply contains all operator controls,

receptacle. A Slave Power Supply may be connected in

ter Power Supply. All signal inputs/outputs, gas, and torch
connections are still connected to the Master Power Supply
when the Slave Power Supply is used. The Slave Power Supply
has the same power circuits as the Master Power Supply. The
Master Power Supply can also be connected to a second Mas-
ter Power Supply and the equipment will automatically be con-
figured when the parallel cable is installed. Many options and
accessories can be added to further improve the versatility of
the system.
