POWER FEED ® 10M DUAL WIRE FEEDER
If the selected weld mode uses one or more wave con-
trols, pressing the left pushbutton will sequence the
selection from weld mode -> wave control 1 (if active) ->
wave control 2 (if active) -> wave control 3 (if active) ->
wave control 4 (if active) then back to weld mode.
The right pushbutton (Item 9) is used to select attributes
that affect the available weld parameters such as pre-
flow time, burnback time, etc. Since most users will
require infrequent access to these attributes, they are
separate from weld mode selection and wave control
adjustment.
LAYOUT-DIGITAL DISPLAY
The MSP4 display consists of a large 4-digit, 7-segment
LED display, two 8-character alphanumeric LED dis-
plays and one 16-character alphanumeric LED display.
The information shown on the various displays depends
on the state of the user interface as described below.
When the MSP4 is being used to select a weld mode,
the 4-digit display (Item 2) indicates the selected weld
mode number. The upper 8-character alphanumeric dis-
play (Item 3) indicates the electrode type (steel, alu-
minum, etc.) The lower 8-character alphanumeric dis-
play (Item 4) indicates the electrode size (.035", 1/16",
etc.).
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 recom-
mended gas (e.g. HeArCO2).
When the MSP4 is being used to change the value of
an attribute, the 7-segment displays show the selected
attributeʼs value. The upper 8-character alphanumeric
display is typically not used while changing an
attributeʼs 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 LEDʼs 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 illu-
minated. 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 avail-
able. The MSP4 alphanumeric displays will then dis-
play 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 pushbutton
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 modeʼs electrode
type, electrode size and process information will
appear.
WELD MODE SEARCHING
The Weld Mode Search feature allows the selection of a
welding mode based on certain criteria (wire size,
process type, etc.).
SEARCHING FOR A WELD MODE
To search for a mode, turn the control knob until “Weld
Mode Search” is displayed. This will appear in between
the highest and the lowest weld mode numbers.
Once “Weld Mode Search” is displayed, pressing the
right pushbutton labeled “Begin” will start the search
process.
During the search process, pressing the right pushbut-
ton typically acts as a “next” button and the left pushbut-
ton typically acts as a “back” button.
Rotate the control knob then press the right pushbutton
to select relevant welding details such as welding
process, wire type, wire size, etc.
When the final selection is made, the PF10M™ will
automatically change to the weld mode found by the
Weld Mode Search process.
Earlier products may not have this feature. To activate
this feature, a software update may be needed from
