People were not really able to determine if these were genuine Hakko or some very very detailed fakes, down to the packaging. IIRC Hakko wasn't exactly helpful in determining if they were original or fake. Since Hakko is no stranger to dealing with fakes one would expect that Hakko would be quick to point out a fake. When they aren't one has to ask if they got caught with their pants down. |

How hard would it be to use a dimmer switch to make a variable-power soldering iron? Of course, it's not true variable temperature, but it's at least better than the average Maplin fire starter. |

This is how el-cheapo irons work, the under $20 types are simple dimmers in a fixed temp iron. Alas, most all cheapos do not use temp feedback, so it doesn't compensate for the heat sunk when soldering, most noticeable on large planes and tracings. An ideal iron should keep tip temperature constant despite load, and better irons use, often proprietary means, to ramp up quickly to minimize variations, this is the difference between the basic technology of Hakko's 936, which everyone copies, or the Weller WES51, and the Metcal technology [ and their new clones] and the gamut of cost of those different systems. If one is going to pay more than $100 for a temp regulated station, it should provide better soldering capability, and make work easier to perform. The value of temp regulation and a temp maximum defined over decades of work are reasons soldering stations have a standard to look to, usually mandated only in commercial work, the IPC standard. --- Quote from: tom66 on November 16, 2012, 05:45:41 pm ---How hard would it be to use a dimmer switch to make a variable-power soldering iron?

Not hard at all. Used to be quite common back when cheap stations weren't available. Today the Chinese supply them ready made: http://www.china-zhongdi.com/zd-99.htm |

That's great, enjoy. In the US this station begins at $400 so its in a different league, I hope it meets your needs. At that price it competes with JBC longer well respected reputation. Its unusual to work with a setting of 190C as in most instances touching a tracing often causes most iron tips to drop 30-50C as the solder and tracing sink heat, if an iron is set at 190C that would put the tip temp below melting point of even PbSn solder. There was a thread of an owner who complained about improper readings on his unit. https://www.eevblog.com/forum/general-chat/weller-soldering-station/msg72641/#msg72641 --- Quote from: andersm on November 15, 2012, 04:37:10 pm ---My current soldering station (WD1000M) is digital, and I can't say I've missed analog control. On the other hand it's powerful enough that I just set it to 190C and solder everything with that. --- End quote --- |
