Everlast 210EXT review and pictures

[GUNNER]

I had a chance to start messing with the double pulse. It's pretty cool, it really seems to lower the amount of heat being put into thin aluminum. I started using the wave forms a little bit, you can see and hear the difference in the arc, but I'll have to spend some time to really see how these different wave forms perform.

This machine has different wave forms? WOW !! I did NOT know this... Please report what you think Todd.... I wasn't so impressed with different wave forms on my Dynasty to be honest... Although I haven't had a chance to weld anything really thin where I wanted to experiment any...

It has a Sine wave, Advanced square wave and Soft square wave ( The soft squarewave looks like a clipped triangle wave ). I have been doing 3/16" and heavier, so the waves haven't made much difference, I did need to boost the amperage when I switched to the Soft square wave. I like the feel and sound of the Sine wave, it has that old transformer smoothness to it. I think the differences in the waves will show up more in thinner metal.

Mark (or anybody else who knows), do the waveforms also apply to DC pulse shaping?

[Rodsmachineshop]

Sine wave can be dc or ac it the wave going neg to pos , plus the time it on each side . square wave is when it flattens on each side of wave To avoid this problem in very sensitive circuits such as precision analog-to-digital converters, sine waves are used instead of square waves as timing references.

[redbeard]

Yep, the pulse is just a waveform centered at some DC level instead of 0, I know that it CAN be shaped, just curious if it is implemented on this machine.

[Rodsmachineshop]

pulse and frequency work hand in hand frequency is how long it stays on each side and balance is how much on each side of pos or neg

This is funny Todd because I like the old sine wave over the others as well.... Funny, I have all these choices on one of the most loaded machines ever made and I like the oldest choice on the thing! I think we are showing our age my friend! Perhaps you can teach old dogs new tricks but they'll always revert back to their comfort zone!!

Mark (or anybody else who knows), do the waveforms also apply to DC pulse shaping?

Pulse and AC wave form are separate things completely. Pulse is pulsing amperage between two given values, regardless and independent of polarity. Waveform is the AC switching from full + to full - half cycle voltage and how it is switched, if short and sudden without any ramping, it is a square wave. A sine wave is more gradual, and not full one way or the other.

Rod,
Frequency is actually how many times a full cycle is made between - and + and then back to the beginning of -. Balance is how much time is spent in each part(+ or -) of the cycle.

Ed,

The wave forms are AC only, the waveform buttons are disabled when you are in DC, so there is no pulse shaping.

There are the 3 different AC waveforms that I listed. Sine, advanced and soft. ( the 210EXT does not have the independant amplitude setting of the 250EXT, The 250EXT does not have the waveforms of the 210EXT )

Pulsing on this welder just switches from high to low amperage at a specified rate in AC or DC,..... EXCEPT for the Double pulse option.

Double pulse uses the set AC wave form the high amperage part of the pulse, and DC for the lower amperage part of the pulse. It's something I will have to use more to figure out what the best applications are.

All these settings are like having extra tools in your tool belt, you are going to use 1 or 2 of them most of the time, the others will be used much less, but they will be very handy when they are needed.

I love the new advertised rating of 3/8" capability and the 1/4" electrodes. Amazing what that extra 10 amps that is digitally controlled can get you over the 200DX.

Do you really believe 10 amps will accomplish all that ? 10 amps is 10 amps no matter how it's controlled.. 10 amps won't weld 1/8 worth of material. More like .010" of material which is .115 short

Where did you see the advertising?

He may have seen them here.

Was this 250EXT listed on the website and later taken down due to an issue? I am currious if all the info on the website is up to date?

Are the IGBT modules manufactured by International Rectifier the same for the 210EXT & 250EXT units?

No, the 250EXT uses infineon.

Well, that's definitely making a pretty strong statement from the Canadians. I'll let them defend it. I'd say though, it's probably a little overreaching,unless a high helium blend is used... and for the 1/4" stick electrode, I just don't think it's realistic for a solid, stable arc.

[performance]

So the PowerTig 250EXT is using these four channel Infineon BTS5440G chips encased inside those black IBGT power modules at the bottom of the unit?

No, that's not an IGBT.
It's the white blocks under the green circuit boards.

Yes I thought those specs on the Can site were a little on the high side. The 210EXT looks like a decent machine but so far I'm content with my 250EX for now.

[Rodsmachineshop]

I think the 250ex is the best tig welder you can buy , have use helium with it also some times when welding thick aluminum head puts out some real heat . had my Denise my friend stop by at the shop he owns a welding shop and he used my 250 to see how it welds , he liked it better than his miller

Ah ha... only two white blocks.
I wonder how many Infineon chips are inside those.

I didn't know you had a store in Vancouver, BC? The reason I say this is whom ever placed that add is high as a kite on BC Bud!! That dog won't hunt!
