The Mobiflex 400-MS/HE is designed for intermittent or
continuous welding applications as indicated above.
The Mobiflex 400-MS/HE filter is recommended for
annual consumable use of approximately:
• 550 lbs (250 kg) GMAW or FCAW or GTAW
• 385 lbs (175 kg) MMA or SMAW or autogeneous
Variables such as coatings (e.g. oil), base material,
weld process, humidity and procedures can affect filter
life and performance.
LFA 3.1/4.1 MOBILE
MANUAL/AUTOMATIC
The LFA 3.1/4.1 Mobile Manual and Mobile Automatic
Extraction Arms are flexible fume extraction arms with
a 360° rotatable hood. Incorporated into the arms hood
is a throttle valve that can be fully opened, partially
opened or completely closed to control airflow at hood
opening. The hood features an airflow focus vane,
which directs the air into the hood.
The armsʼ balance system increases its durability and
stability. As soon as the arms are raised, they are free
to move in any direction. Once the arms are posi-
tioned, they are fixed into place. This makes reposi-
tioning the arms simple, easy and effortless.
The extraction arms are made of solid, lightweight, 8
inch (203 mm) diameter dent and scratch resistant
tubes. They are provided with a spring balance system
for ultra-light, user friendly positioning of the arms.

The K2633-2 and K2633-4 LFA 3.1/4.1 Mobile
Automatic arms contains an integrated Lamp & Arc
Sensor Kit in the hood. The 35W/24V halogen lamp
provides additional light to the workpiece. With the use
of a delayed arc sensor, the extraction fan will operate
automatically. The automatic start/stop utilizes a 20
second auto stop to help conserve energy and reduce
noise level.
