Lincoln Electric POWER MIG IM736-D - Manual (Page 26)

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 300 will have 4 dashes (----) to indicate
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 300 is designed to enable synergic
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 300 as a work point for the POWER
MIG 300 (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 300 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 300 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 300 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 300 to a value lower
than the actual WFS.
Remember: The dialed in SPD value at the POWER
MIG 300 does not control the WFS at the spool gun.
Rather, it is adjusting the POWER MIG 300 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 FEEDING CONNECTION
ADAPTER KIT (K2154-1)
The push-pull adapter kit provides direct connection of
a Cobra Gold or Prince XL torch to the
POWER MIG 300
wire feeder welder.
The kit is intended for use with the following Cobra
Gold or Prince XL torches:
Cobra Gold
Air Cooled 15’(5m) K1589-1 Water-Cooled 15’(5m) K1590-1
Air Cooled 25’(8m) K1589-2 Water-Cooled 25’(8m) K1590-2
Air Cooled 50’(15m) K1589-3 Water-Cooled 50’(15m) K1590-3
Prince XL
Air Cooled 15’(5m) K1591-1 Water-Cooled 15’(5m) K1592-1
Air Cooled 25’(8m) K1591-2 Water-Cooled 25’(8m) K1592-2
Air Cooled 50’(15m) K1591-3 Water-Cooled 50’(15m) K1592-3
Remove all input power to the POWER MIG 300
before installing the Connection Adapter Kit.

Refer to the Owner ’ s 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 PRINCE XL
OR COBRA GOLD 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 300 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 300 is inactive. The actual WFS being set
at the torch is displayed on the POWER MIG 300 .
• All weld parameters normally available for the active
weld mode are available during push-pull operation.
Refer to the Operation Section of this manual.
