The serviceability of a product or structure utilizing the Fume
Extraction Arms is and must be the sole responsibility of the
builder/user. Many variables beyond the control of The Lincoln
Electric Company affect the results obtained in using the Fume
Extraction Arms wirefeeder. These variables include, but are not
limited to, welding procedure, plate chemistry and temperature,
weldment design, fabrication methods and service requirements.
The available range of the Fume Extraction Arms may not be
suitable for all applications, and the builder/user is and must be
solely responsible for welding settings.

General Description
Located in the hood is a throttle valve that can be fully opened,
partially opened or completely closed to control airflow. The arm
features a focus extraction spoiler which directs the air into the
hood.

ManUal operation

The extracted welding fume enters the extraction arm via the
rotatable hood. The arm discharges the polluted air to a filter unit
or directly to the atmosphere. The hood of the arm is fitted with a
throttle valve, which can be controlled using the rotary knob(s).
The throttle valve is mostly used when several extraction arms are
integrated in a line installation; in such configurations closing the
throttle valve prevents the loss of costly heated air.
NOTE: If an automatic damper system is part of the assembly,
keep the manual damper open at all times.
