GENERAL DESCRIPTION
The LN-10 is a single head, 42 VAC input, 4-roll wire
feeder. A single control with dual procedure presetta-
bility of wire feed speed (inches per minute or meters
per minute) and arc voltage is used in conjunction
with a Lincoln constant voltage (CV) welding power
source.
The LN-10 wire feeders have controls providing key-
pad or remote selectability of either of two proce-
dures. Also offered are four independently selectable
gun trigger modes for each procedure; cold feed, 2-
step and 4-step trigger and spot weld. The unit incor-
porates 4 selectable, presettable timers for each pro-
cedure. Preflow, postflow, burnback and spot weld
can all be preset.
Arc starting can be optimized for each procedure with
5 selectable wire feed acceleration rates. A gas
purge key is provided, as well as cold feed forward
and reverse keys with independently adjustable for-
ward feed speed settings.
