CHANGING ARC WAVE CONTROL
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.
CHANGING WELD SEQUENCE BEHAVIOR
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-display
panel. This blinking is used to indicate that start wire feed
speed and voltage/trim can now be set to values different
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-dis-
play LED’s, indicating that crater wire feed speed and
voltage/trim now can be set to values different from those
used while welding.
INFRARED (IR) CONTROL
The MSP4 interface includes an infrared transceiver. This
allows wireless machine configuration using a Palm OS
based hand held computer. A proprietary Palm OS appli-
cation, Weld Manager, was developed for this purpose.
(Contact Lincoln Electric for more information on this fea-
ture.)
LOCKOUT/SECURITY
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 elec-
trode type (e.g. 4043) and/or a description of the rec-
ommended gas (e.g. HeArCO2).
When the MSP4 is being used to change the value of
an attribute, the 7-segment displays show the selected
attribute’s value. The upper 8-character alphanumeric
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.
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 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 display 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 display the
weld mode information for the mode number that was
selected when the machine was last powered down.
CHANGING WELD MODES
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 number is
displayed. As the MSP4 encoder knob is rotated, 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.
