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 Drives (K679) use 4-Roll drive roll kits
with 2 driven rolls, per Table C.1 in ACCESSORIES.
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 DH wire
drive units. Installation instructions are included with
the kits.
Series Double Head Drives use 4-Roll drive roll kits
with 4 driven rolls, per Table C1 in ACCESSORIES.
Each head requires a separate drive roll kit.
