Choosing and Using a Welding Fume Extractor

In any metal shop, the need to manage welding fumes is paramount. Regulations from the Occupational Safety and Health Administration demand it, and the use of a welding fume extractor occupies an honored place in their list of recommended welding practices.

Choosing a Welding Fume Extractor
To achieve the greatest degree of success, it's vital to choose the fume extraction system most appropriate for your situation. The three major types include:

• Source-Capture Fume Extractors - These devices stop the flow of toxins at their point of origin.
• Low-Vacuum, High-Volume Fume Extractors - Large ductwork arrangements enable appliances to move large quantities of air with relatively low vacuum pressure.
• High-Vacuum, Low-Volume Fume Extractors - A provision of nozzles or similar small attachments permits them to remove toxic vapors closer to the actual weld.

Using the Welding Fume Extractor
The most appropriate fume extractor will be of little benefit if not used correctly. Best practices mandate that welders:

• Position the extractor's arm at the correct angle.
• Assume the proper body position.
• Avoid over-welding.

The shop, for its part, must:

• Restrict cross-ventilation.
• Keep the fume extractor properly maintained.
• Educate workers on best welding practices.

Welding fumes are hazardous by nature. By assisting in their removal, the appropriate welding fume extractor plays a vital role in supporting the health and safety of workers in any metal shop.
