CAUTION
4.1 CONTROLS (See Figure 4-1)
4.1.1 Power Switch (ON-OFF)/(I-O)
The power switch is located on the front panel of the power source. In the "off" ("O") position, the unit is shut down; however,
power is still present in the unit. To fully shut down the power source, power must be disconnected at the line disconnect
switch or the fuse box.
With the switch in the "on" ("I") position, power is provided to the main transformer and the low voltage control circuitry.
4.1.1.1 Power Indicator
This white light will indicate that the power switch is in the "on" position and power has been applied to the main transformer
and low voltage circuitry.
4.1.1.2 Fault Indicator
This red light will indicate that current was flowing through the external ground conductor. It will also illuminate if a short
occurs (momentary or permanent) between the +12 volt J1-E; the +10 volt (J2-E) and either the chassis ground or the nega-
tive terminal of the power source. The power source output terminals are de-energized and the fault must be corrected
before resuming operation.
4.1.2 Output Panel/Remote Switch
With this switch in the "Panel" position, output voltage is controlled by adjusting the voltage potentiometer on the front
panel to the desired output. In the "Remote" position, output is controlled using an optional remote voltage control via
receptacle J2.

Never operate the power source with the cover removed. In addition
to the safety hazards, improper cooling may cause damage to the
components. Keep side panels closed when unit is energized. Weld-
ing helmet, gloves, and other personal protection should always be
worn when welding.
