That's the answer I was looking for. With the large size of the fan (thickness) I wasn't sure if that meant more pitch in the blades and lower RPM (quieter) or just a GIANT high speed fan (noisier). I'm glad it is the former. I didn't mean to wind anyone up over variable speed fans, it was just a question. Personally for shop equipment most fan noise is negligible. Compressors are another story, which is why I like to have mine live outside or once I put the pump and motor portion up on the roof.

BTW I'm sure I have a computer with much louder fans than the 255EXT. http://www.youtube.com/watch?v=ad73ZKAbrkw

Any info on the brand of caps?

For me, I find the fan louder...I can't remember the name of the capacitors. I believe it's the standard we use in the 250ex and others. Korean name, if I remember right. Name brand, but I'll have to or Mike will to post.

I think there is a decibel meter app for android. I'll try to download it if its free, and maybe mike has one and we can objectify the readings at the machine, 5 ft...10ft..inside a shop environment.

Interesting topic, I need to thank Rambozo for asking all the questions I had:-)

I like what is being reported, as looking at the pix, Mark's machine has a black fan, and Mike's has a blue fan. I am hoping that the later builds use the quieter blue fan.

The correct way to get a sound pressure level measurement on these machines is to send mine to me, and I'll take a reading and report back. Until then, the pictures are nice to peruse. Any more vids in the works on this machine?

Still ready in Kent,

Jim

If it is as quite as my MTS250S I will be happy my PowerTig 250EX is nosier then my compressor and my Power Plasma 60S cutter is also.
The compressor is a screw type 5.5 HP 25 CFM @ 125 PSI.

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 :D

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.

(A) weighting Sound level Meter I did this with my sound meter.
--------------- PT250EX---PP60S---MTS250S
At 1 ft in front: 89dB ---- 78dB ----- 63dB
At 5 ft in front: 74dB ---- 68dB ----- 56dB
At 10 ft in front: 70dB ---- 66dB ----- 54dB
At 20 ft in front: 65dB ---- 63dB ----- 52dB

Marks Samsung Galaxy not bad for android apps. But outside for me in the country is real quite.
At 1 ft. in front: 74dB
At 3 ft. in front: 71dB
At 5 ft. in front: 70 dB
At 10 ft. in front: 68 dB

Great vids, pics, and info, guys. Keep it coming!! :)

I'm obviously no electronics expert, but I am baffled that these machines can function so reliably but fry my garage stereo from 10ft away. They probably look the same on the inside, too.

Shouldn't hurt your stereo, but can definitely cause massive interference while welding. Especially during the HF start.

I have 80-81db at front and back (right on the case pretty much), 69db 4-5 feet away from the front. I don't think it's that bad. People pay for a 100+db rock concert :D

This one has the blue fan. I think Mark has the black one. So the blue was 5db less.

the inside of the 250EX and the 255EXT are very similar it should be a very good machine the 250EX is.

The "final drive" so to speak is very similar.

Mike,
I think the 5 ft measurement was essentially the same...which the 5-10 ft range would probably be more typical of a use type situation. These fans can be bought in any color imagineable, including red, yellow etc. Mine was taken with the all the doors closed, and the machine running about 2 feet from the back wall.

The final drive is the same, 250amps of power.

I have just under 70 at 5'. I'm not bothered by the fan. So long as it welds I am happy.

What does the weight finally come in at?

In the manual it said it was 60Lbs bare weight. (http://www.everlastgenerators.com/do...TIG-255ext.pdf)

Ok,
Since you guys 'like' updates...here's one...as I understand it from Oleg
We should be good to go in 10 days or less. There are a couple of minor things that you guys should be aware of that we became aware of after things shipped out from the factory. I don't think this will be a real issue for anyone. Not sure if you guys could see the pictures Mike posted of his unit he received in advance, but the unit was labeled as a 250EXT. Before we decided to rename the unit, I drew up a label and sent it to them. Then I redrew a new one when we made a name change and sent it to them. They got it right for the first test units, but in this first production batch they pulled the wrong file and put the wrong label on the face, with the 250EXT. The label is replaceable with a little effort, and the correct one can be sent out to you if desired.

Also we're thinking that they probably got the torches wrong based off Mike's unit he got shipped in advance. They'll likely come with the standard torch and accessories, but we'll have the upgraded accessory package sent out to you as soon we have them available. If this proves to be true through the entire production run, we will try to get them asap.

Or the alternative is to wait a good bit longer for the next production run of units.

No one's happy about the little snafu but there's not a lot to do at this point.
