GENERAL DESCRIPTION

Lincoln

s LFA extraction arms are spring-balanced for

easy positioning. They are intended for use with a
low-vacuum, high-volume extraction fan. The LFA
arms are commonly installed on a Mobiflex 200-M
mobile base unit with filter or with an SF2400 Wall-
Mounted Extraction Fan, with or without a Statiflex
200-M Wall-Mounted Filter Unit. Extension Cranes are
available in 7 ft. and 14 ft. lengths, with an optional
Feeder Hanging Rail. Lamp Kits available for both the
Mobiflex and Wall-Mounted Systems provide hood-
mounted switches for the light and connected fan sys-
tem. An Automatic Start/Stop Arc Sensor can be
installed with either lamp kit to automatically start the
connected extraction system (Mobiflex 200-M or
SF2400 Fan) when the sensor detects a welding arc.

Installation procedures for the K1655-1 and K1655-2,
LFA 3.1 and 4.1 Extraction Arms have been com-
bined; the difference between the arms is the length of
the arm sections, which does not affect installation
procedures.
