MINIFLEX ® PORTABLE WELDING FUME EXTRACTOR

RECOMMENDED USES

Read and understand this entire section before operating
your MINIFLEX.
WARNING
Always operate this equipment with the filters installed
and covers in place as these provide maximum
protection from moving parts and insure proper vacuum
operation and cooling air flow.
The MINIFLEX is a portable, high vacuum welding fume extractor
designed for the removal and filtration of welding fumes released
from the following welding processes:
• MIG/MAG solid wire (GMAW)
• MIG/MAG flux cored wire (FCAW)*
• Stick welding (SMAW)
• TIG (GTAW) welding
*For light duty flux-cored applications only.
WARNING
Use of the product for extracting and/or filtering fumes
and/or gases that are released from the following
processes is not recommended:
• Welding applications with intensive use of anti-spatter
spray, paste or solution.
• Autogenic or plasma cutting spray/molten metal.
• Arc-air gouging.
• Welding that produces the release of a dense oil mist.
• Paint spraying.
• Extraction of hot gases [more than 104° F (40° C)].
• Extraction of aggressive fumes (such as acids).
• Grinding aluminum and magnesium.
• Flame spraying.
• Extraction of cement, saw dust, wood dust, etc.
• Extracting cigarettes, cigars, tissues and other burning
particles, objects and acids.
• Any dangerous situations where there is a risk of an
explosion or fire.
Note: The MINIFLEX does not filter any shielding gases. Gases pass through
the filter. MINIFLEX used with optional carbon filter may reduce vapors
and gases.
