Is this really a way to set the amperage on a 200 DX ?

[Jake98]

They're leaving you out of the loop Mark, this is not good.

Here's some pics of my pedal

My 200DX pedal has a different number on it:



It looks like you got the 47K pot on yours.

Whats the difference? Im assuming the pot is the potentiometer

[Joe from NY]

i think Mark can explain that for us.

[Tinker]

Externally my pedal looks just like the one that Buzz has but it's got the adjustment pot/knob to the left of the cable. The part number is the same as Joe's (FT-2.2K-CL) so I'm guessing that Joe and I have exactly the same pedal. I took a good look at mine when I first rec'd the unit and made a few resistance measurements. The pot that's operated by the pedal measures about 2.3K ohms at max resistance, close enough to the 2.2K I figure is indicated by the pedal part number. The knob pot measures 48K ohms at max resistance. I looked at the schematic of the "new" pedal in the forum and mine is close except the schematic shows only a single 47K ohm pot. Maybe that's the one Buzz has?

My pinout looks like:
1 - 2 = The start switch closure.
3 - 4 = The pedal pot resistance.
3 - 5 = The knob pot resistance.
6 - 7 = Connected together.

I'd have to take the pedal apart to make sure I've captured all the connections. Perhaps Mark can confirm that the schematic posted on the forum is the FT-47K-CL version that Buzz has and if there is a schematic of the FT-2.2K-CL available?

I should have some time later today to fire up my 200 DX and make a few more observations of how it operates vs. the one that Buzz has :^)

It would be quite nice if the only difference between the way our units operate is the pedal but that may be wishful thinking until we get more answers or we dig into things a bit more. Mark we're not trying to drive you crazy with all these detailed questions but you may be dealing with a couple or few perfectionists in this post :^)

What happens If you set your amperage on the panel, say 100 amps but set the pedal to max, wouldn't the panel over ride the pedal?

How many "green" knobs do you have on the bottom row?

[Buzz]

How many "green" knobs do you have on the bottom row?

I have 3, Preflow, postflow and down slope. I see the pic on the website only has 2 , post flow and down slope.

[Jake98]

you have some extra features there. pulse range is different too.

[Joe from NY]

Well, it looks like I ordered my 200DX about a month too soon. The new one has more features.

[sportbike]

Hopefully the upgrades are here to stay.
Interesting that no one seems to know about them.

[Jake98]

I'm wondering if the display is an upgrade, or we just got mis-matched pedals. Is the pedal knob the culprit?

[performance]

No,
There were a handful of these models produced to field test some new features. They got jumbled into our regular stock it looks like I just assumed everyone knew they had gotten a "special" model.

There are some upgrades to the unit that will be going on that will be permanent...such as a dual voltage model.

Wow, after all this discussion I'm certainly very disappointed in the product management, configuration control and the documentation we've been exploring. The pedal I've got on my 200 DX seems to match the one posted that's identified as the "Super 200 PI". The one that's identified as the one that's used on the IGBT line (like my 200 DX???) sounds like the one that Buzz has on his unit. Confusing.

No Jake98 unfortunately just changing to the "new" knob-less pedal isn't going to make the display and panel knob on our version of the 200 DX work the way we expected it to operate or like the one that Buzz was lucky enough to receive. I did a few experiments with my pedal and it won't change the operation of our units.

One of you guys made a comment about the design/factory folks needing to keep the rest of the team in the loop in order to effectively address these kind of discussions. I'll second that thought.

Looks like some of us may have just missed getting a design that works the way we would have expected it to operate right from the get go. I can live with the fact that product enhancements are going to take place adding features like the pre-flow, etc. but I am disappointed that the operation of the display, panel knob and the pedal knob wasn't made clear in the specs or literature. Would I have bumped up to the 250 to get a unit that operated the way I expected along with some additional features? After all this discussion, quite possibly...

Tinker,
I think you misunderstood.
I was in the LOOP on things. Who do you think designed the new panel features for that unit? I don't work in the California office. So, I am not worried about every detail that happens out there. I knew those units were out, hence my question about the number of green knobs. Someone got it shipped to them. Actually, that should be a pleasant surprise. I just didn't know that everyone who received one wasn't aware of the unit "specialness". If anything it ought to prove we are working on product improvements. The boxes are identical. They all have 200DX. The DX has ALWAYS had the knob on the pedal. The "new" DX IF it were to be offered would include a substantial price increase, most likely. This was a limited run of units that are not being produced at this time. You also haven't looked at our website, because in bold letters, it tells you that the 200 DX is different and how it works. There are pictures, that are very clear of the panel as well. The fault is not ours on this one. It IS in black and white...and green. Scroll down the page and read. This has been there for well over a year now. http://www.everlastgenerators.com/Po...DX-351-pd.html

We do everything we can to inform the customer about the product. It is there. Short of having a loud voice come on the computer speakers and shout at you that is.

That would be great! Can you really do that??

Tinker,

I sure wasn't. I never would have known had I not read this thread. Im diggin the "specialness" I haven't tried it on AC yet, although I dont thing it would make a difference.

[Tinker]

Well I can see that we've exhausted this thread... Mark, no misunderstanding I was just seconding the point that Jake made in post #21. Back in post #11 your comment that "UNLESS for some weird reason you can limit amps on the panel" didn't help to put our questions to rest.

I'd disagree that the operation of the panel display is clearly described on the web site. " Digital readout for accurate setting of amperage controls." had me thinking that it operated in a similar way in all modes with or without the pedal. I haven't used everyone's welder but don't most all of them work that way? The foot pedal spec states "YES/OVERIDES PANEL AMPS. SET/LIMIT MAX AVAILABLE AMPS ON WITH KNOB ON PEDAL". While after reading this thread, a few others and actually playing with the unit I now realize that the panel knob and the pedal knob work completely differently along the digital display. IF the pedal knob overrode the panel knob BUT the digital display preset the max amps for either knob I'd have less of a disagreement with the specs as documented. Sure I could have called to make sure how it operated but I'd assumed it would work like the other machines I've used so I didn't know to even ask

Also as I pointed out the pedal documentation that's included in the forum seems a bit inaccurate. The schematic for the new pedal for the IGBT line (which includes the 200 DX, doesn't it?) posted back in August 2009 shows just a single 47K pot. That sounds like the one that Buzz rec'd for his IGBT 200 DX but not what some of the rest of us rec'd.

So far my particular 200 DX has performed very nicely as a welder it's just the unconventional way it handles the display, panel and pedal knob that's a bit of a disappointment... Does it really impact it's usability as a welder, no but it still bugs me. Yea, after all this I would have sprung for the 250 or at least the 225 and been delighted with the display. Crazy, well I've been called worse ;^)
