If the selected weld mode uses any of the four available
wave controls, users can press the left MSP4 pushbutton
until the ARC CONTROL LED is illuminated. The value,
name and units (if applicable) of the available wave con-
trols will appear. Note that the name of the control is
derived from the weld table and may not necessarily
appear as "Wave Control". Repeated pressing of the left
MSP4 pushbutton will cycle through all active wave con-
trols and then the weld mode. Turning the MSP4 encoder
will change the value of the displayed wave control.

Weld sequencing attributes are grouped into two cate-
gories, START OPTIONS and END OPTIONS. START
OPTIONS may include Preflow Time, Run-in Wire Feed
Speed, and Start Time. END OPTIONS may include
Spot Timer, Crater Time, Burnback Time and Postflow
Time. The attributes that appear in the START and END
OPTIONS are weld mode dependent. For example, if a
TIG weld mode is selected, Run-in WFS will not appear
since it is not relevant to the selected process. Repeated
pressing of the right MSP4 pushbutton will cycle through
all relevant START and END OPTIONS. Turning the
MSP4 encoder will change the value of the selected
option.
When the Start Time attribute is set to a value other than
OFF, the START OPTIONS LED will blink synchronous
with the WFS and VOLTS/TRIM LED’s on the dual-dis-
play panel. This blinking is used to indicate that start wire
feed speed and voltage/trim can now be set to values dif-
ferent from those used while welding. Similarly, if the
Crater Time attribute is set to a value other than OFF,
the END OPTIONS LED will blink synchronously with the
dual-display LED’s, indicating that crater wire feed speed
and voltage/trim now can be set to values different from
those used while welding.

The MSP4 interface includes an infrared transceiver.
This allows wireless machine configuration using a Palm
OS based hand held computer. A proprietary Palm OS
application, Weld Manager, was developed for this pur-
pose. (Contact Lincoln Electric for more information on
this feature.)

The MSP4 can be optionally configured to prevent the
welder from changing selected user interface controls.
By default, all user interface controls can be changed.
Weld Manager software (for Palm OS or PC) must be
used to lock or unlock user unterface controls and to set
a pass code.

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.

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.

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.
