K1542-12 MSP2 Panel: (Optional)
This panel provides a selection of over 25 weld
modes, including CV, pulse, FCAW and CC, through
a toggle switch and indicator lights (LEDs). It allows
for adjustment of all set up parameters, Preflow, Run
In, Arc Control, Burnback, Postflow, and Crater,
through an up/down toggle switch, indicator lights and
a 3 digit display.
To adjust a set up parameter (Weld Mode being one
of those parameters), first select one of the set up
parameters for adjustment, and then adjust the dis-
played value up or down.
Set up parameters are selected with the Select switch,
an up/down center-off momentary toggle switch.
Moving the switch bat up or down moves an LED in
the corresponding direction. Holding the switch in
either direction will cause the indicator to move quickly
in the corresponding direction until the switch is
released, or the upper or lower limit is reached.
The value of the active set up parameter is shown on
the MSP2 panel digital display. The value can be
modified with the Set switch. The Set switch is an
up/down center-off momentary toggle switch. Moving
the switch bat up or down adjusts the displayed value
in the corresponding direction. Holding the switch in
either direction will cause the display to move quickly
in the corresponding direction until the switch is
released, or the upper or lower parameter limit is
reached.
To energize the output studs in either CC/Stick mode,
the right Control/Display panel knob, labeled
Volts/Trim, must be used. The Volts/Trim knob must
be turned clockwise roughly a quarter revolution to
energize the output studs. (The Volts/trim display will
indicate ‘On’ when the studs are energized.)
Similarly, turning the knob a quarter turn counter-
clockwise de-energizes the output studs. If a CC/Stick
weld mode is entered through use of the Dual
Procedure, the studs will be in the same state as
when they were last used. If a CC/Stick weld mode is
entered through a Memory recall, the studs will be de-
energized.
K1640-1 Dual Procedure / Memory Door Panel:
(Optional)
This panel provides two functions: Dual Procedure
and Memory. Dual Procedure provides for setting and
manual selection of two procedures. Selection can be
done at the panel, or through a dual procedure weld-
ing gun switch connected to the Wire Drive trigger
receptacle. Memory provides six independent storage
locations for Control Box settings. All selections are
done with push buttons and indicator lights. Dual
Procedure can be used without making use of
Memories; the opposite is also true.
To set Procedure A, hit the Procedure button until the
A LED illuminates. Make all desired settings on the
Control Box. Settings are automatically saved as
changes are made. Do the same for procedure B. If
using a gun switch to select procedures, hit the
Procedure button until the Gun LED illuminates.
When in the Gun mode is selected, either light A or B
will be flashing. The flashing light identifies the
Procedure, A or B, which is selected by a dual proce-
dure gun switch. If no dual procedure switch is
plugged in, the Procedure defaults to A. Settings are
saved at power down.
To load a memory, start by setting all adjustments and
functions on the Power Feed to the desired settings.
To save the settings to Memory 1, simply hit the Save
button (its red light will illuminate) and then hit the 1
button. The settings are now saved in Memory 1. The
contents of Memory 1 will not change, even if the
power is turned off, until the next time the Save key
and the 1 key are hit in sequence. The same proce-
dure can be applied to each of the other 5 memories.
If the Save key is hit accidentally, simply hit the Save
button again, its light will go out, and the Save func-
tion will be canceled.
Note: It is not required to load all 6 memories at once,
nor is it necessary to load them in order. Memory can
be loaded at any time, except when welding.
Similarly, the Save key is not active while the gun trig-
ger is pulled, or while welding.
Memory has an advanced feature called ‘memory
reminder’. When the Save key is hit, the memory
reminder function flashes the LED of the most recently
used memory, so the operator can save procedures in
the most recently used memory if desired. It is not
necessary to save to the most recently used memory;
the memory reminder function, and it’s flashing LED,
can be ignored.
Memories cannot be changed without using the Save
key. When slight procedure adjustments are neces-
sary, but there is no desire to ‘permanently’ save the
adjustments to a memory, this can be done with
Procedure A and Procedure B. Set the Panel to A or
B, and recall a memory setting. Make the slight proce-
dure adjustment -- it will be saved in A or B, whichev-
er was selected when the adjustments were made.
The memory location will not have changed.
