4.DUAL ENCODERS – Accurately adjust weld parameters as pre-set values, or on-the-fly values while welding.

5.SWITCH PANEL – Heavy-duty pushbutton switches that control inching of the wire, starting and stopping of weld- ing, travel and flux control. The Switch Panel can be removed and turned into a remote pendant.

6.START – Activates the weld cycle.

7.STOP – Deactivates the weld cycle.

8.TRAVEL MODE:

ON – Activates travel. OFF – Disables travel.

AUTO – Activates travel when the START button is pressed. Disables travel when the STOP button is pressed.

9.FLUX FILL – Activates the flux hopper.

10.INCH UP – Feeds the wire upwards, away from the work.

11.INCH DOWN – Feeds the wire downward, toward the work. NOTE: The Power Feed 10A includes an option in the Setup Menu (P.15) to enable the touch sense circuit- ry in the power source. Having this feature enabled will stop the wire when it comes in contact with the work, engaging the flux hopper on contact for automatic flux fill. The flux hopper will disengage when the INCH DOWN button is released.

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 dis- plays 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 display will show "Initializing…" while waiting for the Weld Sequencer to configure. The Mode Select Panel alphanumeric displays will then display the name of the weld table loaded in the attached power source while the user interface prepares the machine for operation. After all initialization is complete, the Mode Select Panel will dis- play the weld mode information for the mode number that was selected when the machine was last powered down.

WIRE FEEDER SETUP

Use the INCH UP / INCH DOWN pushbottons to insert wire into feed mechanism. Prior to inserting the wire, make sure the Touch Sense option is disabled (P.15 in the Setup Menu).

INCH WIRE FEED SPEED SETTING

While pressing either the Inch Up Pushbutton or the Inch Down Pushbutton, the preset wire feed speed will be dis- played on the Dual Display panel. This value can be changed while inching wire by turning the WFS Encoder and will be stored into memory.
