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,
Burn back, 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 CW at
least 45° to activate the output (turning CCW 45° deacti-
vates the output). This prevents the output from inadver-
tently 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 procedure 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.
