Lincoln Electric IM539 Synergic 7F and 7FH - Manual (Page 14)

PROCEDURE TO INSTALL DRIVE
ROLL AND GUIDE TUBES
Standard 4-Roll Kits (KP571 and KP572)
1) Turn off welding power source.
2) Release both quick release levers by sliding the
levers sideways into the open positions.
3) Remove hex screw & clamping collar from the
drive shaft closest to the incoming side of the
feeder.
4) Install drive roll onto keyed shaft. Double grooved
drive rolls are to be installed with side stencilled for
correct wire size facing out and with slotted spacer
on top of roll. Two piece drive rolls use a spacer
between the rolls for .068” (1.7mm) and larger wire
sizes. (Do not exceed the maximum wire size
rating of the wire drive.) Replace collar and
tighten clamping screw.
5) Back out the set screw for the middle guide tube.
Install the middle guide tube and slide it up against
the drive roll. DO NOT TIGHTEN THE MIDDLE
GUIDE AT THIS TIME.
6) Install the outgoing drive roll following the same
procedure as steps 3 & 4.
7) Center the middle guide between the two drive
rolls and tighten in place.
ELECTRIC SHOCK can kill.
• Do not touch electrically live parts such
as output terminals or internal wiring.
• When inching with gun trigger, electrode
and drive mechanism are “hot” to work
and ground.
• Turn OFF welding power source before
installing or changing drive roll and/or
guide tubes.
• Welding power source must be connected
to system ground per the National
Electrical Code or any applicable local
codes.
• Only qualified personnel should
perform this installation.

Wire Feed Drive Roll and Guide Tube Kits
NOTE: The maximum sizes the Synergic 7F will feed
satisfactorily are the 3/32” (2.4mm) cored and
1/16” (1.6mm) solid electrodes. The
maximum sizes the synergic 7FH will feed
satisfactorily are the .045 (1.2mm) cored and
.045” (1.2mm) solid electrodes.
The electrode sizes that can be fed with each
roll and guide tube are stencilled on each part.
Check the kit for proper components.
