FAQ
What should I look for when choosing a welding fume extractor?
Match airflow to your process and how close you can place the capture nozzle; closer placement reduces the airflow required. Prioritize portability (carry handle vs cart), filtration stages you’ll maintain consistently, and power compatibility with your shop. Check consumable costs for pre‑filters and main filters, and make sure hose length and nozzle style suit your fixtures and typical part sizes.
How much should I spend for good value in a portable fume extractor?
Value depends on duty cycle and how often you move the unit. Spending more typically gets sturdier housings, higher airflow potential, better wheels or handles, and more filtration options. If you weld occasionally at one bench, a simple portable model is often sufficient; for longer sessions or frequent repositioning, a cart‑based unit can justify a higher price due to easier mobility and capacity.
When is a portable unit better than a cart‑based mobile extractor?
Choose a portable carry unit if you lift the extractor onto benches, work in tight spaces, or travel between jobs where stairs and vehicles are involved. Opt for a cart‑based model if you mostly stay on one shop floor, need longer reach with larger arms, or want less lifting. A good rule: if moves exceed a few times per day, wheels reduce fatigue and speed setup.
How should I care for filters and maintain performance?
Use a pre‑filter to capture larger particles and extend the main filter’s life. Replace consumables according to the manual and your actual usage, not just calendar time. Keep the nozzle close to the arc, avoid sharp hose bends, and inspect hoses and seals for leaks. Store the unit in a dry area, and clean or replace nozzles that accumulate spatter or debris.
Why is my fume extractor losing suction, and what should I check first?
Start with capture technique: move the nozzle closer and angle it toward the plume. Inspect the pre‑filter and main filter for loading; replace if airflow remains weak. Check for hose kinks, obstructions, or loose clamps that introduce leaks. Confirm the power source and extension cords are appropriate for the unit. After restoring flow, note replacement intervals to prevent repeat issues.
