An increased desire to maintain optimal welding operator safety and to attract new skilled welding operators to the field is also a consideration in investing in this equipment — companies want to create the most comfortable and healthy work environment possible.

Some companies may opt for centralized fume extraction systems, which are designed to protect the entire shop area. These systems involve the installation of new ductwork

Laboratory Fume Extraction Arms are available in a variety of amperages, cable styles and handle designs. As with any welding equipment, they have their advantages and limitations, best applications, maintenance requirements and more. In combination with many other variables in the welding operation — welding wire selection, specific transfer methods and welding processes, welding operator behavior and base material selection — fume extraction guns can help companies maintain compliance with safety regulations and create a cleaner, more comfortable welding environment.

The basics of fume extraction guns
The welding fumes that these guns remove are composed of a combination of the filler metal and base material. Some fume extraction guns feature adjustable extraction control regulators at the front of the gun handle, which allow welding operators to increase suction as needed (without affecting shielding gas coverage), while others provide this function internally. Regardless of the manner, the ability to balance between the downward flow of shielding gas and the upward flow of the suctioned air is critical. The fume extraction gun needs to provide the appropriate amount of shielding gas to protect the weld from defects such as porosity, without sacrificing the ability to suction fumes efficiently enough to protect the welding operator. The balance allows the weld pool time to react and solidify, and gives the fume particles time to decelerate so they are easier to extract.

As an important medical device in the operating theater, it solves the problem of the sight interference caused by the shadow to the doctor, greatly improving the safety of the operation during the surgery.

And of course, we’ve been seeing its development in the history of medicine. To this day, the surgical light equipped with DVR allows doctors to observe the operations in every corner of the world without being crowded in the operating room.
