5.2 42 VAC INPUT POWER CONNECTIONS
Your Wire Feeder comes factory ready with a harness to plug directly into all 14 pin
Lincoln Power Sources equipped with 42 VAC auxiliary.
The 42 VAC is connected to the PC Board on terminal strip J5 #1 (neutral) and #2
(hot) and Ground to the Cabinet chassis.
5.3 POSA START CONNECTIONS
Posa Start circuitry aids welding starts by sensing arc establish signals. A weld ground signal is required for this to circuit to work, which is provided through the Power Harness to the Power Source and is internally connected to the P.C. board on terminal strip J6 terminal 2.
Note: Place polarity switch to DCEP. Refer to scetion 7.3 for power supply settings to insure proper Posa Start operation.
WARNING: TURN THE INPUT POWER TO THE POWER SOURCE OFF AT THE DISCONNECT SWITCH BEFORE PERFORMING ANY WORK.
WIRE THREADING PROCEDURE
6.1 WIRE SPOOL INSTALLATION
Release latches, and open right side door of cabinet.
Remove spool retainer from spindle hub.
Install wire spool onto spindle hub so that wire feeds from bottom of spool towards slave motor. Make sure that the hole in the spool aligns with pin on spindle hub. The white dot on the end of the spindle hub will aid in this alignment.
Replace the spool retainer.
6.2 THREADING PROCEDURE
Place wire size selector switch on front panel to the correct position for the wire being used.
Loosen end of wire from spool and cut off any kinked or bent portions.
Unreel and straighten out first 6" to 8" of wire.
Release tension from slave motor drive rolls.
Route wire into inlet guide, along drive roll groove, and into wire conduit.
Prevent the wire spool from turning with the palm of the right hand, and at the same time grasp the slave motor pressure adjusting knob.
Pull the torch trigger and slowly tighten the slave motor pressure adjusting knob until the slave motor stalls.
CAUTION:
EXCESSIVE DRIVE ROLL TENSION WILL REDUCE RATHER
THAN IMPROVE WIRE FEED PERFORMANCE.
