AC/DC – Push the AC/DC button to select DC (Direct Current) output or AC (Alternating Current) output. The green
LED will light indicating the output selected. When AC output is selected the Wave Balance and AC output Frequency
Parameters are active and can be set through the control knob when selected with the Scroll Buttons.
CONTACTOR – Push this button to turn the output contactor on in STICK Mode.
CONTROL – Push this button to switch between Panel control and Remote control.
PULSE – Pushing the Pulse button turns ON or OFF the Current Pulser. The green LED will light when the Current
Pulser is active. With the Pulser active the PEAK Current, Base Current, Pulse Width and Pulse Frequency can be set
through the Control Knob when selected with the scroll buttons. Selection is indicated when the green LED lights.
Digital LED Display – Welding current and parameter values are displayed in this window. The display will show
settings in Hertz (Hz), Seconds (sec.), Percent (%), and
Amperage (A) indicated by the lighted LED above the screen.
Internal warnings such as over temperature, low or high input
voltage applied are signaled to the operator by a warning
sound and error message on the screen. The warning sound
will activate when the power source is turned off.
Control Knob – Allows the operator to adjust the output
current within the entire range of the power supply, also used
to set each parameter value in the Sequence Graph. Pushing
the knob inward displays the actual welding voltage. The welding voltage is for reference purposes only and is not a
machine adjustable value.
Detailed description of each parameter can be found in the Owner's Manual.
SANARG 300AP SETTINGS
The settings shown below should be used as guidelines for a first set-up. The welder should adjust these setting
to achieve optimal weld performance for the specific application.
