Lincoln Electric IM859 POWER MIG 350MP - Manual (Page 28)

C-2 C-2 ACCESSORIES
Non-Synergic Weld Modes (Mode 5)
• Voltage is adjustable at the power source. The
right control knob on the power source will
adjust the voltage that is displayed in the meter
directly above it.
• The left Display (WFS / AMPS) on the POWER
MIG ® 350MP will have 4 dashes (----) to indi-
cate that the left control knob on the power
source is inactive. Wire Feed Speed is set at
the Spool Gun.
• The following procedure settings for Aluminum
4043 can be used as initial settings for making
test welds to determine final settings:
Wire Dia. WFS Setting Arc Voltage
In. (mm) Spool Gun Setting
.030" (.8 mm) 270 15V
.035" (.9 mm) 250 16V
3/64" (1.2 mm) 240 20V
4. Synergic Weld Modes
The POWER MIG ® 350MP is designed to enable syner-
gic weld modes and synergic pulse processes with the
spool gun. The actual wire feed speed (WFS) of the
spool gun must be measured and manually set on the
POWER MIG
® 350MP as a work point for the
POWER MIG ® 350MP (SPD).
• In synergic modes when the spool gun trigger is
pulled, an adjustable value for the SPD work
point is displayed in the left meter. The letters
SPD are displayed in the right meter.
• The left control knob adjusts the SPD value.
The right control knob is inactive.
• Measure the actual WFS, in inches per minute,
at the spool gun and set the SPD at the
POWER MIG
® 350MP to match this value.
WFS can be measured by pulling the trigger of
the spool gun and feeding wire for 6 seconds.
Measure the length of wire (in inches) that was
fed and multiply by 10.
• The POWER MIG ® 350MP is now configured
and ready to weld in the synergic mode.
• Adjustment of the SPD value from the set value
has the affect of adjusting trim or arc length.
• To increase the arc length; increase the SPD
value at the POWER MIG ® 350MP to a value
higher than the actual WFS.
Remember; do not change the WFS at the spool
gun.
• To decrease the arc length; decrease the SPD
value at the POWER MIG ® 350MP to a value
lower than the actual WFS.
Remember: The dialed in SPD value at the POWER
MIG ® 350MP does not control the WFS at the spool
gun. Rather, it is adjusting the POWER MIG ® 350MP
synergic work point. Therefore, adjusting the SPD
value will not change your actual WFS at the spool
gun. WFS can only be changed at the spool gun.
PUSH-PULL TORCHES
Remove all input power to the POWER MIG ®
350MP before installing the Connection Adapter
Kit.
-----------------------------------------------------------
Refer to the Ownerʼs Manual of the Torch for
Amperage and Duty Cycle rating information. The
torch rating may not match the rating of the power
source.

MAKING A WELD WITH THE PUSH PULL
TORCH INSTALLED
• Set the idle roll pressure on the wire drive between
an indicator reading of 0-2. A recommended start
point is 1.5.
• Set the Gun Selection toggle switch located inside
the wire drive compartment directly above the push-
pull control cable connector to "PUSH-PULL GUN."
• Depending on the weld mode, set the Voltage or
Trim at the POWER MIG ® 350MP using the right control
knob located on the upper case front panel.
• The Wire Feed Speed (WFS) is set using the control
knob on the Torch. The left control knob on the
POWER MIG ® 350MP is inactive. The actual WFS
being set at the torch is displayed on the POWER
MIG ® 350MP .
• All weld parameters normally available for the active
weld mode are available during push-pull operation.
Refer to the Operation Section of this manual.
