Welding fume extraction hoods should be placed close enough to the welding arc to be effective, yet not so close as to distrub shielding gases or obstruct the welders line of vision.  We call the optimal distance from the arc the sweet spot, and the sweet spot is determined by placing the edge of the […]

The short answer is that a respirator protects the welder wearing it, but does nothing for nearby workers not wearing similar protection. The somewhat longer answer is that a repirator, as good as they are in protecting the person wearing one, does not capture and contain weld fumes in the general atmosphere.  As such, other […]

The practice of using fans and blowers in this manner is called the dilution method, and while it is commonly used, this method may not be effective in removing weld fumes in any except the smallest of shops. Disadvantages include lack of uniformity in diluting the fumes throughout the shop, downstream concentration of fumes as […]

There are currently no “blanket” regulations prohibiting the placement of used filters into standard trash receptacles. Local authorities, however, may place certain restrictions on this procedure, so we advise checking with applicable agencies to ensure conformance with regulations

Used filters can be easily removed from Ace extractors. We recommend the operator wearing gloves and protective eyewear, placing the removed filters into a trashbag, sealing the bag, and placing the bag in a trash receptacle.

There is no clear answer to this question as too many factors can influence the life of filters, including, but not limited to, welding process, type of materials, condition of materials, run times, position of extraction hood relative to the arc, welder skill level, ambient air movement, humidity, and more. Filter status indicators are included […]

Ace makes a wide variety of filters available that work in combination to provide the best possible filtration for your work application. Generally speaking, 95% main filters and standard pre-filters provide effective filtration for the vast majority of welding operations. HEPA main filters can be used in place of a 95% filter to provide additional […]

Filters are rated on their efficiency to stop and trap particulate of a particular size. Most filters used in Ace extractors base their efficiency rating on stopping particulate of 5 microns or greater. A micron is 1/25,400th of an inch in diameter, and most carbon steel welding particulate is approximately 5% microns in size. So […]
