28.5 Volt Adjustment; Line Drop Compensation; Voltage Regulator Adjustment - Hobart JET-EX 4 Operation And Maintenance Manual

(3) Adjust the screwdriver adjustable pot at the point shown in the illustration. Turn it counter
clockwise to increase the speed at which the engine will shutdown. Turn it counterclockwise to de-
crease the shutdown RPM.

5. Voltage Regulator Adjustment

A. 28.5 Volt Adjustment
The regulating voltage, in the 28.5 volt range, is determined by the position of the wiper arm of the
multi-turn potentiometer R46 Clockwise (CW) rotation increases the voltage level at which the unit op-
erates. Conversely, counterclockwise (CCW) rotation decreases the voltage level.
B. Line Drop Compensation
Line drop compensation allows the voltage at the load end of the output cable to remain constant de-
spite the voltage drop associated with the output cable. Clockwise (CW) rotation of the single-turn po-
tentiometer (R24) increases the compensation. This potentiometer should be set for flat regulation of
voltage at the load end of the output cable when delivering rated load current.
