Welding fume extractors play a crucial role in maintaining a safe working environment for welders. These devices are designed to extract harmful fumes and gases generated during the welding process. To ensure the effectiveness of these extractors, proper maintenance and troubleshooting techniques are essential. In this article, we will discuss some important maintenance and troubleshooting tips for welding fume extractors.
Maintenance Techniques:
- Regular cleaning: Regular cleaning of the filter is necessary to maintain the effectiveness of the fume extractor. Depending on the usage, the filter needs to be cleaned daily or weekly.
- Inspection of ducts and hoses: Check the ducts and hoses for any signs of damage, cracks or wear and tear. If any damage is found, replace the damaged parts immediately.
- Check the fans: The fans are responsible for drawing the fumes and gases out of the working area. Make sure the fans are running smoothly and there are no obstructions in the way.
- Lubrication of moving parts: Regular lubrication of moving parts such as fans, bearings, and motors can help prevent wear and tear and prolong the lifespan of the extractor.
- Calibration of airflow: Calibration of the airflow is essential to maintain the correct extraction rate. Calibration should be carried out periodically, as per the manufacturer’s guidelines.
Troubleshooting Techniques:
- Reduced airflow: If the airflow from the extractor is reduced, it could be due to a clogged filter or a damaged fan. Check the filter and clean it, and if the fan is damaged, replace it immediately.
- Noise from the extractor: If the extractor is making excessive noise, it could be due to a damaged fan or a loose component. Check the fan for any damage, and tighten any loose components.
- Failure to start: If the extractor fails to start, check the power supply and the wiring. Make sure the power supply is connected and the wiring is not damaged.
- Odor or smoke: If there is a smell or smoke coming from the extractor, it could be due to a clogged filter or a damaged fan. Check the filter and clean it, and if the fan is damaged, replace it immediately.
In conclusion, proper maintenance and troubleshooting of welding fume extractor are crucial to ensure the safety of welders and maintain the effectiveness of the extractor. Regular cleaning, inspection of ducts and hoses, checking the fans, lubrication of moving parts, and calibration of airflow are some essential maintenance techniques. In case of reduced airflow, noise, failure to start, or odor or smoke, it is essential to troubleshoot the problem immediately to prevent any safety hazards.
