K1542-11 MX2 PANEL (LARGE PANEL)

The MX2 Panel provides a selection of four Power Source modes. In addition, it provides for the adjustment of the following parameters: preflow, run in, arc control, burnback, postflow, and spot time.

Descriptions

Indicator Lights - Extra bright red LEDʼs for viewing at almost any angle. Always indicate the mode and active parameter being displayed.

Display - Extra bright, 3 1/2 digit, .56” (14.2 mm) charac- ter height, red LED display for viewing at almost any angle. Displays the value or status of the active parame- ter.

Available Modes -	CV/MIG
	CV/ FLUX CORED
	CC/STICK CRISP
	CC/STICK SOFT

Due to the nature of the system, the following feature is required for safety reasons: upon entering any constant current (CC) mode, the right encoder, labeled “Volts, Trim” on the Display/Control Panel acts as a “soft” con- tactor switch. The encoder knob must be turned Clock Wise at least 45° to activate the output (turning Counter Clock Wise 45° deactivates the output). This prevents the output from inadvertently becoming “hot” when scrolling through the weld modes. The exception to this rule is when the weld mode is entered by a change in procedure (using a memory panel such as the K1542-9 Memory/Dual Procedure panel). In this case, the state of the contactor is recalled as it was left when the proce- dure was exited.

In the CC modes, the output current is set by the Amps control, and the Volts/Trim adjustment has no effect in this mode. In this mode, the Arc Control adjusts the arc force. Increasing the Arc Control setting increases the arc force, making the arc more harsh but less likely to stick. Decreasing the Arc Control setting decreases the arc force, making the arc softer and smoother.

Parameter Ranges:

PREFLOW - 0.0 to 2.5 seconds (0.1 sec. increments). RUN IN - Low Range: 50 to 150 IPM (1.25 to 3.80 MPM).

-High Range: 75 to 150 IPM (2.00 to 3.80 MPM). ARC CONTROL - Trim (-10.0) to (+10.0) , (0) is nominal. BURN BACK - 0.0 to 0.25 sec. (0.01 sec. increments). POSTFLOW - 0.0 to 2.5 sec. (0.1 sec. increments).

CRATER - ON or OFF (Functions in 4 step trigger mode only).

Mode Selection

The MODE SELECT switch is a momentary large bat three position toggle switch that defaults to the center (off) position. Moving the switch bat up advances the mode indicator in the upward direction, down advances it

in the downward direction. Holding the switch in either direction will result in the indicator advancing at a high rate of speed in that direction, until the switch is released. When the indicator reaches its upper or lower limit, advancing ceases until the direction of the switch is changed.

Parameter Selection

The PARAMETER SELECT switch is a momentary large bat three position toggle switch that defaults to the center (off) position. Moving the switch bat up advances the parameter indicator in the upward direction, down advances it in the downward direction. Holding the switch in either direction will result in the indicator advancing at a high rate of speed in that direction, until the switch is released. When the indicator reaches its upper or lower limit, advancing ceases until the direction of the switch is changed.

Parameter Adjustment

The value of the active parameter, as defined by the parameter indicator, is displayed on the parameter dis- play. The PARAMETER SET switch is a momentary large bat three position toggle switch that defaults to the center (off) position. Moving the switch bat up advances the displayed value in the positive direction, down advances it in the negative direction. Holding the switch in either direction will result in the displayed value advancing at a high rate of speed in that direction, until the switch is released. When the indicator reaches its upper or lower limit, advancing ceases until the direction of the switch is changed.

Crater fill operation is covered in the WIRE DRIVE OPERATION section.

Installation is as follows:

1.Turn off power.

2.Remove the two screws from the front of the stan- dard or option panel at the location you choose to install your new option, (bottom), of the Control Box cabinet. Save the screws for re-use. Unplug the white electrical connector. Remove the chassis wire (if equipped) from the back of the standard or option panel. Discard the old panel or save for future use.

3.Tilt the new option panel away from the front open- ing of the Control Box cabinet and plug the white electrical connector into the proper connector (12 pin) on the right side of the main printed circuit board until the connector latches into place. Attach the chassis wire (if equipped) to the back of the new panel.

4.Slide the new panel through the opening, taking care not to damage the connections and the printed cir- cuit board on the back.

5.Align the screw holes, replace the two screws and tighten.
