I don't think you're being fair. Maybe I did get a little carried away about your product manual--OK. Let me say I think it could be improved. I gave an example of what I consider to be a better written manual for a similar product. And maybe I shouldn't have said in a previous post that your cooling system engineer didn't ace fluid dynamics--maybe he did. Sorry. I don't think the MTS-200 has a particularly quiet cooling system.

I assume you want feedback from your customers, or you wouldn't be operating this forum. If you do want honest feedback, you've got accept that sometimes not all feedback is positive. On the other hand, I left some negative feedback, too. Pls see positive comments in my posts, for example the opening comments of my first thread.

So in the interest of improving Everlast products and customer experience, let's not shout and let's not call names. But, by the way, you have called me names i) malconent, ii) Monday-morning quarterback, iii) and, I think, techno-something. Well, maybe I am a techno-something. I have a University of California undergraduate math degree and a Caltech Ph.D. (you know my name, check w/ the registrars if you don't believe me.)

I made the detailed comparison between the Thermal Arc unit and the MTS machines in part because you suggested in responses to my posts that fan on demand degrades duty cycle. I'm not trying to be antagonistic--I think this is a legitimate technical issue worthy of discussion in a forum of this type. The 181i vs MTS offers an excellent natural experiment concerning this question. Here are two very similar (built in the same factory) inverter multi-process machines, one with FOD and one without. Yet when you look at the rated duty of the machines, they appear to very similar. All I'm saying is , where's the big duty-cycle hit caused by FOD? (My underlying assumption here is that the published duty cycle figures are accurate--I assume they are for a variety of legal reasons.)

I also asked in a previous post about potentiometer control of amperage in the MTS machine, and ways to implement TIG-mode remote amperage control. As I stated there, and state here again, I _understand_ that user modifications to a machine would void its warranty. No one expects a seller to warrant a machine when its been modified outside of seller's control. If you don't want to discuss user-modifications to your machines for liability or any other reason, that's your business and I have no problem with that. If you don't even want the subject brought up for discussion by forum members--well, it is your forum. The reason I brought up this question again and made some comparisons with the 181i is that Everlast technical support said the MTS-200 front panel amperage control isn't potentiometer-based, but rather relies on digital encoders. I find this interesting for a couple reasons. I actually have some real-world experience with encoders, and I don't think this would be my first choice to implement amperage control--mainly for cost reasons. I'm not trying to be antagonistic--I think this is a reasonable topic of discussion in this kind of forum. Can you comment again on how the amperage control is setup on the MTS 200 and why digital encoders were used? If this is a trade secret, or you don't want to discuss it, OK. Again comparing with the apparently similar 181i, its documentation states the amps controller is a pot. You guys may have decided to go a different route, I'm curious why.

Let me ask a final question. Is there a simple way you know of to use small diameter wire rolls on the MTS-200? Please, you don't need to say I'm not much of a welder, there's no need for such a feature, etc. I like the machine, OK? I'd like to use small rolls now and then--it'd make me like the machine even more. Is there a straightforward modification that would let me do this?

So ban me if you want--I think you're being a little sensitive. You guys must be used to some rough and tumble--I don't think you're in an easy business. If you do decide on such a ban, pls advise snail mail addresses for technical questions, etc.
