LAYOUT-CONTROLS (SEE FIGURE b.3)

The MSP4 panel controls (Items 7 and 9) set consist of an encoder knob Item 8 and two push buttons. The encoder is primarily used to change the value of the selected attribute.

The left pushbutton (Item 7) is used to toggle between Weld Mode selection and any active Arc Controls (a.k.a. wave controls). The choices of wave controls varies by weld mode. For example, weld mode 31 has one wave control, “Pinch”. Weld mode 110 has three wave controls, “Peak Current”, “Background Current” and “Tailout”. If the selected weld mode has no wave controls, pressing the left pushbutton will have no effect. If the selected weld mode uses one or more wave controls, pressing the left pushbutton will sequence the selection from weld mode -> wave con- trol 1 (if active) -> wave control 2 (if active) -> wave control 3 (if active) -> wave control 4 (if active) then back to weld mode.

The right pushbutton (Item 9) is used to select attribut- es that affect the available weld parameters such as preflow time, burnback time, etc. Since most users will require infrequent access to these attributes, they are separate from weld mode selection and wave control adjustment.

LAYOUT-DIGITAL DISPLAY

The MSP4 display consists of a large 4-digit, 7-seg- ment LED display, two 8-character alphanumeric LED displays and one 16-character alphanumeric LED dis- play. The information shown on the various displays depends on the state of the user interface as described below.

When the MSP4 is being used to select a weld mode, the 4-digit display (Item 2) indicates the selected weld mode number. The upper 8-character alphanumeric display (Item 3) indicates the electrode type (steel, aluminum, etc.) The lower 8-character alphanumeric display (Item 4) indicates the electrode size (.035", 1/16", etc.).

The 16-character alphanumeric display (Item 5) indi- cates the process type and other information, the exact content of which depends on the selected weld mode. This additional information may include specific electrode type (e.g. 4043) and/or a description of the recommended gas (e.g. HeArCO2).

When the MSP4 is being used to change the value of an attribute, the 7-segment displays show the select- ed attribute’s value. The upper 8-character alphanu- meric display is typically not used while changing an attribute’s value. The lower 8-character alphanumeric display is used to indicate the units of the selected attribute (e.g. seconds, in/min, etc.). The 16-character alphanumeric display is used to display the name of the selected attribute.

The content of the displays while the user interface is being used for advance machine configuration (e.g. limit setting, pass code entering, machine setup, etc.) is described in later sections.

POWER-UP SEQUENCE

When power is first applied to the machine, a lamp test is performed. All discrete LED’s are turned on, all 7-segment displays will show a pattern of "8." and all alphanumeric displays will show a hatch pattern where every-other pixel is illuminated. The lamp test will last for two seconds, after which all displays are turned back off. The 16-character alphanumeric dis- play will show "Initializing…" while waiting for the Weld Sequencer to announce bus available. The MSP4 alphanumeric displays will then display the name of the weld table loaded in the power source while the user interface prepares the machine for operation. After all initialization is complete, the MSP4 will dis- play the weld mode information for the mode number that was selected when the machine was last pow- ered down.

CHANGING WELD MODES

To select a weld mode, press the left MSP4 pushbut- ton until the WELD MODE LED is illuminated. Turn the MSP4 encoder until the desired weld mode num- ber is displayed. As the MSP4 encoder knob is rotat- ed, only the weld mode number is displayed. After 1 second of encoder idle time, the user interface will change to the selected weld mode and the new mode’s electrode type, electrode size and process information will appear.

WELD MODE SEARCHING

The Weld Mode Search feature allows the selection of a welding mode based on certain criteria (wire size, process type, etc.).

SEARCHING FOR A WELD MODE

To search for a mode, turn the control knob until “Weld Mode Search” is displayed. This will appear in between the highest and the lowest weld mode num- bers.
