Why is the setback feature called INSTANT setback when it is delayed? Wouldn't automatic setback be a more suitable name?
Marketing terminology I guess. FWIW, my Weller gear reminds me of this (WD1 base unit had user settable timers), but add in the optional setback stand, and even more settings come into play.
Makes it rather customizable, but also a bit confusing. Definitely RTFM territory.
But note that it was never our intention to design a "JBC Killer" ... we just wanted to produce a solid, low cost, reliable soldering station...[snip].
As Dave mentioned in his review, perhaps a better comparison would be against the Hakko 951. From a cost of ownership basis, JBC is double the price for the initial cost and more than double the price of our tips, so we need to have realistic expectations. We will be successful in 90-95% of the applications, and against the competition, even JBC, in standard applications.
From what I see, it does need a few kinks worked out in software, but you've otherwise accomplished that IMHO. The comparison between the ADS200 and FX-951 is certainly valid for those in the US/CAN market. Harder in other markets, but I'd really like to see it paired against an Ersa i-Con 1 or 2 (150W using conventional plated tips).
As per EEVBlog's statement of using the lowest temp possible temp POV, I get where he's coming from. Unfortunately however, it's more important to have the temp set where the joint is made properly in 1 -2 seconds without damaging either the component or board IME (minimal dwell time).
For example, the 600F/316C for low temp cases, 700F/371C for the vast majority of soldering cases, and 800F/427C for the really high demand stuff was commonplace in lead-based processes for this purpose. And the fact that 315C, 325C, and 350C are the standards I've seen for lead-free alloys, this still seems to be the case (though 350C seems to be the most common).
Either way, the set temps are at least 100C above the alloy's melting point (i.e. 183C for 63/37 or 217C for SAC305).
Bit of a side note, I'd rather see metric sizing than imperial for tip labels as I find it easier to picture 2.4mm than 3/32".
