How close should a high vacuum/low volume exhaust inlet be located to the source of welding fumes? 2^n104^n(5to10cm) 6^nto8^n(15to20cm) 12''(014''(30to36cm) at least12feet(3.66meters)away

The correct answer is: $6^{n}to8^{n}(15to20cm)$<br /><br />Explanation: The high vacuum/low volume exhaust inlet should be located 15 to 20 cm (6 to 8 inches) away from the source of welding fumes. This distance ensures that the fumes are effectively captured and removed from the welding area, reducing exposure to harmful fumes and improving air quality.
