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

[JimMinKent]

We do have 4 excellent functioning AC wave forms, 500 hz DC(although the one I tested was set to 250hz...one of the programming things I referred to) and 250Hz AC pulse (advanced square wave, with the alternate wave forms capable of 10 hz each, which I think is a reasonable expectation. 3 amp operation on DC, 5 amp operation on AC. And for the videos, I took several "light ups" on a sprite can, which I'll put together. It doesn't like to start the arc if you run a ball. It prefers a point, which is not an issue at all. It will start, but it makes it more difficult. It is a capacitive discharge HF like the i tig 200T. .

Mark, can you please clarify a couple of statements from your earlier post, thank you.

First, regarding the frequencies stated, Does changing the waveform limit the AC frequency? Which would not be expected, or did you mean using Advanced Pulse limits the pulse frequency, which has been discussed and we are expecting.

Doesn't the AC frequency range run full scale regardless of which of the 4 waveforms is selected? I am not sure why you made the distinction between "advanced square wave" and the "alternate wave forms" with regard to the "10 hz".

If this was a slight misstatement, and you meant to describe "Advanced Pulse" mode, then fine, but then please answer this, Are all 4 waveforms still available in Advanced Pulse, at all AC frequencies, albeit limited to Advanced Pulsing at 10 hz?

Second, even a pointed electrode will ball slightly in AC, with any balance setting, at the very tip. Only a freshly ground tungsten is sharp on the first strike. You are not saying this level of sharpness is needed for good starts in AC are you? This would not be expected.

Thanks for the clarification,
Really ready in Kent now,
Jim

Jim,

In context of the DC at 500 hz, and the word pulse, I thought it was clear, but my apologies for not communicating clearly. I'll try again.

I was referring to pulse frequency in AC, not the frequency of AC itself. The range of AC frequency is the same regardless of wave form. But in regular pulse mode, the alternate wave forms other than Advanced square is limited to a max of 10 hz. Advanced square itself, pulse frequency is up to 250 hz. DC is 500 hertz.

All AC wave forms in advanced pulse are limited to a 10Hz PULSE.

No, an electrode shouldn't ball with the lowest setting if it's right...or even up to 35% or so. Anything will ball if too much heat is used for the tungsten size. But in regular use, of course, a tiny amount may disappear off the tip, but it's going to do that with DC as well. It won't form a ball. If it does, something isn't just right. You shouldn't attempt low amp starts with a balled tungsten as it destabilizes the arc. Low amp starts was the context of the idea I was trying to communicate, but as a rule, balls just don't work as well for starts. There's really no reason to purposefully run a ball. This is why inverters don't run well with green tungsten and why it isn't used. Green tungsten forms a ball, and creates, a lazy, unstable arc in an inverter. None of our units run as well with a ball as they do with a pointed electrode.

Mark, Thank you for the update,

I just want to be on the same page with what shows up Still I do wonder what is the challenge in pulsing over 10hz using a triangle, soft square, or sine waveform when the advanced square wave can go to 250hz.

I agree with everything you said regarding the tungsten, and would add that we are talking about not using a balled end where the diameter of the ball equals the diameter of the tungsten.

Here's part one.
Part two will be up soon, hopefully by the a.m. which will include pulse and AC feature settings.
then part 3 etc.

But this is sort of the basic layout, and function of the machine.

Edit: Revised video below.

All looks good so far now just sit and wait. How many amp will the air cooled torch take. Does the 220V outlet for the water cooler go ON and OFF with the power switch on the 255EXT?

The power outlet for the cooler will be on/ off with the power switch on the welder , at least for Canada. I have specified this on my last trip but with new changes it sometimes needs to be told a couple of times to production before it is all firmed up as a normal process.
As for Canadian production it will not be done until I am at the factory to make sure there are no glitches and if there are some found on the production run during testing these will need to be worked out at that time . it will probably be the end of October before they arrive in Canada
As for the pedals here is the insides and also the overall look compared to current models
Cheers

Nice looking pedal I will have to try one out some day

[DVA]

Just watched it on youtube. Somehow the audio levels got off from the original. I'll reload it as soon as I can rerender it, and get it uploaded. Going to take a couple of hours to rerender and load. Can't figure out what happened in the render process.

Nice to see the videos coming. Are there going to be any videos of the machine running? Also, did you get a chance try out the stick functions with the new machine?

[performance]

Revised video is loaded see above. There will be a couple of short ones with welding. Stick functions work great. It will run 6010, but the arc is a little soft on it...kind of strange really as it seems to run more like 7018 with the puddle.

I checked above and I could not find a revised video.

Well I think all looks good with the new 255EXT new ground clamp, new regulator, 2 new torches 25 ft. air cooled and water cooled with consumables and a new stick electrode holder just missing one thing the welder just have to wait and in Canada just a little long but it will be worth it. Everything looks good Everlast on the new PowerTig 255EXT.
