Airborne Noise Emissions
The SR-45i system generates high noise levels while cutting. Depending on the
size of the cutting area, distance from the cutting torch, and arc current cutting
level, acceptable noise levels may be exceeded. Proper ear protection should be
used as defined by local or national codes. The following chart gives the noise
levels generated by the SR-45i when operating at 45 amps, 115 arc volts. The
measurements were made with a sound level meter.
