ATTENTION
The position of the hood should be
approximately 6-12 inch (15-30 cm)
in front of the welding arc.
Performance depends on factors
such as part vs. operator and weld
position, airflow (CFM and velocity
level), ambient conditions and
maintenance. Reposition hood as
needed to maintain efficient fume
capture.
