ABSTRACT:
A fume extracting device (10) for an arc welding apparatus (12) effectively removes fumes from the leading and trailing portions of the arc welding zone (82) while maintaining transverse compactness. The fume extracting device (10) includes first and second body portions (30) individually having an internal fume collecting chamber (50), a plurality of fume inlet passages (54), and a fume exhaust passage (48) and is so constructed that the body portions (30) are maintained in a preselected spaced apart relationship to each other and to the central axis (14) of the welding apparatus (12). Advantageously, first and second gas shielding devices (64) can be individually connected to the one of the body portions (30).
