SYNERGIC 7 & 7H
A-6
Wire Feed Drive Roll and Guide Tube Kits
NOTE: The maximum sizes the Synergic 7 will feed
satisfactorily are the 3/32” (2.4mm) cored and
1/16” (1.6mm) solid electrodes. The maximum
sizes the Synergic 7H 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.

PROCEDURE TO INSTALL DRIVE
ROLL AND GUIDE TUBES
Standard 4-Roll Kits (KP655 and KP656)
1) Turn OFF welding power source.
2) Release both quick release levers by sliding the
levers sideways into the open positions.
3) Remove clamping screw & clamping collar from the
drive shaft closest to the incoming side of the feed-
er.
4) Install drive roll onto keyed shaft. (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.
WARNING
Observe all additional Safety Guidelines detailed
throughout this manual.
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 and could remain energized several
seconds after the gun trigger is released.
• Turn OFF input power at welding power
source before installation or changing
drive roll and/or guide tubes.
• Welding power source must be connected
to system ground per the National
