2.VOLT / TRIM METER - This meter displays either the voltage or trim value depending on the status of the machine. Located below the display is the text "Volts" and "Trim." An LED light is illuminated to the left of one of these in order to indicate the units of the value displayed in the meter.
CV Processes
•Prior to GMAW and FCAW operation, the meter displays the desired preset Voltage value.
•Prior to synergic
•During Welding, the meter displays actual aver- age volts.
•After welding, the meter holds the actual voltage value for 5 seconds. During this time , the display is blinking to indicate that the machine is in the "Hold" period. Output adjustment while in the "Hold" period results in the "prior to operation" characteristics stated above.
•After the 5 second "Hold" period, the meter dis- plays the set Voltage (GMAW, FCAW) or Trim
CC Processes
•The meter displays the status of the output.
•When output is enabled, the meter will display "ON."
•When there is no output, the meter will display "OFF."
3.OUTPUT CONTROLS - The POWER MIG 300 has 2 encoder knobs to adjust weld parameters.
•Each encoder changes the displayed value of the meter located directly above that encoder.
•In
•In
4.THERMAL - This status light illuminates when the power source has been driven into thermal overload.

The eight discrete LED’s are used to identify which selec- tion will be shown on the display. The possible selections are:
• Weld Mode (Process selection choices)
• Preflow / Postflow }
•
• Start
• Arc Control
• Crater
• Burnback
• Spot
Only one LED will be illuminated at any time. The Weld Mode attribute will always be a valid selection (the other attributes may not be available in all processes).
5A. SELECT Toggle Switch
•This switch toggles through the 8 selections detailed above the switch.
•A red LED is located next to each possible selection and is illuminated when that choice can be changed.
5B. Display Meter
•This meter displays the active weld mode (a set of weld parameters that have been determined to pro- vide the recommended results for a particular welding process) when the “Weld Mode” LED is illuminated or when any one of the other seven LED’s is illuminated the meter indicates what value that welding parame- ter has been set to.
5C. SET Toggle Switch
•This switch adjusts (up or down) the value shown on the display meter. When the WELD MODE LED is illu- minated, this switch is changing the weld mode of the machine. The most commonly used modes are dis- played in the chart on the right half of the Multi- Process Panel.
If the LED next to a weld parameter (Preflow/Postflow,
