Benefits of On-Torch Systems
✅ Captures fumes right at the arc for maximum removal efficiency
✅ The extraction point follows the operator, eliminating the need to reposition external hoods or ducting
✅ More likely to be consistently used, especially when the extractor is configured to switch on/off automatically with the welding torch trigger
✅ Well-suited for MIG and flux-cored welding in downhand (horizontal) positions, production lines, workshop use, and routine maintenance
✅ On-torch extractor units are generally lightweight and easy to transport
Limitations of On-Torch Systems
❌ Ineffective for overhead or vertical welding, as rising fumes often escape the capture zone
❌ Not compatible with grinding, Stick/MMA welding, plasma cutting, or gouging processes
❌ The fume nozzle can be bulky, limiting access in tight spaces or intricate joints
❌ Additional hoses and extraction hardware may add weight and reduce handling comfort—design quality varies by model
❌ Poorly matched or designed systems can allow extraction airflow to interfere with shielding gas, risking weld quality
❌ Torch consumables may cost more than standard options, depending on brand and design
❌ Compared to standalone mobile units, on-torch systems typically offer lower fume volume capacity and may require more frequent filter servicing
