WIRE FEED DRIVE ROLL KITS
NOTE: The maximum rated solid and cored wire
sizes for each wire drive head and selected
drive ratio is shown on the SPECIFICATIONS
in the front of this section.
The electrode sizes that can be fed with each roll and
guide tube are stenciled on each part. Check the kit
for proper components.
Synergic 7F Wire Drives (K679) use 4-Roll drive roll
kits with 2 driven rolls, per Table C.1 in ACCES-
SORIES. These kits are common with those used for
the 4-Roll LN-7 GMA and LN-9 GMA Lincoln Wire
Feeders, but are not common with those used with the
10 Series wire drive units. Installation instructions are
included with the kits.
10 Series Wire Drives use 4-Roll drive roll kits with 4
