Fume Tracker™

The Fume Tracker™ is the world’s first self-positioning fume extraction arm for hassle-free welding. It features patent pending technology that detects a weld arc and repositions the capture arm hood above the fume source. Operators are able to eliminate time spent repositioning the hood and focus more on the task at hand. 

The Problem

Using traditional portable fume extractors, a worker must constantly reposition the hood above the fume source to ensure the smoke is captured.  Since the extraction hood needs to be close the weld arc to be effective, the worker either pauses frequently to make adjustments or neglects to use the extraction arm altogether. 

Problem Solved

Using a FUME TRACKER™, every time the worker starts welding within the tracking window, the extractor hood automatically tracks to a precise position above  the welding arc, ensuring fume capture at source.  The welder can now complete the job without the hassle of constant arm-adjustments or the worry of inhaling hazardous welding fumes.  


How it Works

Arc Sensors
The FUME TRACKER™ capture hood is fitted with sensors that detect the welding arc and relay this information to the controller.  Each time the unit is powered on, the controller performs a calibration that allows it to discern the difference between the ambient lighting conditions and the welding arc. The calibration only takes a few seconds, after which, the FUME TRACKER™ is ready to use.

Controller
The controller accepts information from the light sensors, calculates the precise position of the welding arc using an innovative algorithm, and commands the servo motors to move the arm.

Servo Motors
Three servo-driven motor articulations work in synchrony to robotically reposition the arm to a specific point, based on the calculations of the controller.

Field of Detection
The FUME TRACKER™ has a sensibly wide field of detection.  As long as the welder strikes a new arc within the sensing window, the arm will follow.  If the task requires a weld outside the field of detection, the worker need only move the hood manually. The arm compromises several slip clutches to prevent the arm from being damaged when moved by the operator.
