Airborne Noise Emissions; Electromagnetic Compatibility (Emc) - Lincoln Electric spirit II 150 Technical Manual

Section 2: Specifications

Airborne Noise Emissions

The 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
system when operating at 150 amps, 130 arc volts. The measurements were made
with a sound level meter.
Distance From Torch
1 meter horizontal / 1.6
meters above the
workpiece
The maximum noise level is 121 dB at a distance of 3 inches (76.2 mm) from the torch
while cutting at 150 amps, 130 arc volts.

Electromagnetic Compatibility (EMC)

The 380V 50/60Hz and 415V 50/60Hz CE marked Spirit II plasma cutting systems are
manufactured to comply with the European standard EN 60974-10 (Electromagnetic
compatibility (EMC) – Product standard for arc welding equipment). Information about
the EMC standard EN 60974-10 can be found in Appendix A.
