K3972-3 - Lincoln Electric X-Tractor Mini Portable Fume Extractor 120V

High-Vacuum Portable Fume Extraction System

The Lincoln Electric X-Tractor® Mini (K3972-3) is a premier solution for light-duty welding fume extraction, specifically engineered for portability and high-efficiency filtration in confined or hard-to-reach spaces. Operating on standard 120V single-phase power, this unit utilizes a robust 2.4 HP motor to generate significant vacuum pressure, delivering adjustable airflow between 95 and 108 CFM. This high-vacuum capability ensures effective capture of welding fumes at the source, pulling particulates through a multi-stage filtration system.

At the core of the X-Tractor Mini's performance is its filtration efficiency. The unit comes standard with a LongLife-H™ main filter and a downstream HEPA filter, achieving a 99.7% efficiency rating. This level of filtration is critical for compliance and safety, particularly when dealing with hazardous particulates such as hexavalent chromium found in stainless steel welding fumes. The system features a total filter surface area of approximately 118 square feet, maximizing particulate holding capacity while maintaining consistent airflow.

Advanced control features set the K3972-3 apart from basic extraction units. It incorporates an intelligent Current Sensor that automatically detects the welding arc. By looping the ground or work lead through the sensor, the unit automatically activates when welding begins and deactivates approximately 10 seconds after the arc is extinguished. This "on-demand" operation reduces background noise, lowers energy consumption, and extends the life of the motor brushes. Speaking of maintenance, the unit includes a Carbon Brush System that monitors usage and provides an alert after 750 run hours, ensuring proactive maintenance scheduling. With a weight of just 40 lbs and a sound level below 80 dBA, the X-Tractor Mini is a sophisticated, industrial-grade tool designed for the professional welder's environmental safety.
