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 GMAW-P and GMAW-PP oper- ation, the meter displays the desired preset Trim value. Trim adjusts the synergic default voltage as a percentage of that voltage. A trim value of 1 is the default and results in the recommended voltage setting for a given wire feed speed. Adjusting trim to a value of .95, adjusts the volt- age to 95% of the recommended voltage.

•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 (GMAW-P) value.

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 CC-GTAW modes, the left encoder sets the maxi- mum welding current. Full depression of a foot or hand amptrol results in the preset level of current.

•In CC-Stick and CC-GTAW, the right encoder activates and de-activates the output. Turning the encoder clock- wise enables the output if not using a remote trigger device. To de-energize the output, turn the encoder counter-clockwise. The display above will indicate the "ON" or "OFF" status of the output.

4.THERMAL - This status light illuminates when the power source has been driven into thermal overload.

5.MULTI-PROCESS PANEL - This panel enables selection of weld modes as well as adjustment of certain weld parameters within each weld mode.

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

• Run-In

Choice of weld parameters

• Start

that can be adjusted.

• Arc Control

• Crater

each parameter are found

• Burnback

}later in this section.

• 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, Run-In, Start, etc.) is illuminated, the SET switch will adjust the setting of that specific weld parameter. The setting is shown on the display meter.
