SYSTEM FOR MONITORING AND CONTROLLING AIR QUALITY DURING WELDING

A fume reduction system includes an electric arc torch, a consumable wire electrode, an air quality sensor, and a power supply operatively connected to the electric arc torch and the air quality sensor. The air quality sensor monitors air quality near the electric arc torch and generates an air qual...

Zusammenfassung:	A fume reduction system includes an electric arc torch, a consumable wire electrode, an air quality sensor, and a power supply operatively connected to the electric arc torch and the air quality sensor. The air quality sensor monitors air quality near the electric arc torch and generates an air quality signal corresponding to the air quality. The power supply supplies electrical energy for generating the electrical arc and controls the wire feed speed of the consumable wire electrode. The power supply further receives the air quality signal and automatically reduces the wire feed speed from a first positive speed to a second positive speed based on the level of the air quality signal.
