NEW 2013 EVERLAST PowerTig 255 EXT AC/DC DIGITAL TIG WELDER

[performance]

Same fan setup generally as most 250EX and 60S.
MTS has a different fan setup...lower duty cycle as well.

At this point I am too anxious to worry about the fan noise. Also getting close to pushing off my project for ~6 months as I am running out of time waiting for the machine. The updates are looking good though

[performance]

Measured the decibel level, on my Samsung Galaxy with one of the better recommended (as accurate) android apps. This was in my shop with hard walls, 11 foot ceiling etc.


I took a bench mark measurement, which included cars passing on the road @approx 150 ft away, with the shop doors down just for a frame of reference. Then I took it at the back in the middle of the fan area at one inch, then from the front at 1 ft, 3 ft, 5 ft, 10 ft. I then took a side measurement at 5 ft. All measurements were about three feet off the floor, the same height as the welder.

Benchmark: 31 dB
At the fan 1": 86 dB
At 1ft in front: 74dB
At 3 ft in front: 71dB
At 5 ft in front: 70 dB
At 10 ft in front: 68 dB
At 5 ft on side: 70 dB

The phone gave me approximate equivalents of what each dB level meant, and I confirmed it as fairly accurate via other online sources.
30-40dB Quiet whisper at 3ft...library level
60-70dB Normal conversation at 3 ft.
70-80 dB Busy traffic, phone ring tone
80-90 dB Busy Street, Alarm clock

Keep in mind that 3 or 4 decibels makes a significant difference in the loudness. Some of you tech experts on noise, and sound can chime in...and tell me why this is/isn't right.
