content: hi as i wrote in an another topic as an off topic note i have a problem with my soldering station which is a weller wd 1000m kit (wd1m station 160watts, wmrp pencil max 55watts tip dependant 1x55 watts and 12x40 watts tipshttp://www.weller.eu/products.php?pid=299) only thing i can verify its again out of calibration by itself with not much use is set to 100? and it still melts the solder which is a stannol kristall 505 which melts at 183?, unfortunatly i have no such a temperature sensor which can measure atleast up to 150? to atleast do the manual calibration of the unit from its menu or software yet, any idea to solving it till an ordered tip temp sensor arrives or another round to the dealer and try to replace the unit? first time i went back with the whole set to the dealer poor guy was shocked when he tested the unit with an another tip to make sure which has problemQuote

content: Quote from: Kiriakos-GR on November 15, 2011, 01:48:11 amits can be calibrated at the lowest temp setting(100?) +-40? i wont take it apart especially while its under warranty, only softwer adjusment, front panel buttons or usb link with the weller software for their stations, unfornatly no accessable firmware on the weller site to try that way

content: you mean the firmware updater software? as i remember it needs file to upload it does not download anything, and i cant find any firmware to any of the soldering stations, btw i didnt check the fw number when i got it back originally was 1.00, i will email them for a firmware when i can compare the stated temp and the real temp to adjust it and see if it changes by itself or malfunctioning againedit: the unit was made in this years may according to its sticker

I have the FW files for your iron on my home PC and extract them for you next week when i finish lab overhaul if you dont solve the issue sooner (by buying a HAKKO)

content: yep welcome into the europian unionanyway i bought this weller mostly cos i got a nice quality recommendation from 1 of our old technician in the company and i like this micro pencil nice heats up fast and very easy to get there places which are crowded, i dont know any distributor for the hakko in this country but there are few jbc, weller, ersa

content: well the hakko 191 arrived what i ordered from ebay, dunno about its true accuracy but i was shocked when i checked the iron temp with it at 100celsius set temperature 25x celsius.... at 350celius it showed 39x. Quickly go to cal option and try to set it first i thought how the hell i correct that 150celius offset? but it can be done cal range is -+40 celius but you can do several steps set it and set it again and the temperature was about 99-100celius in a few steps saved it and left the menu and checked the whole range its spot on to the hakko +-1-2celius, i would like to test it with a proper k type sensor or the dedicated weller calibrator unit

content: To save money, you can cross check your Hakko 191 settings by checking the melting point of eutectic solder. I have such a 191 myself, likely a copy, and its spot on against eutectic solder and my other thermocouples.Quote from: M. András on December 05, 2011, 04:42:56 pm

content: i checked it with my kristall 505 solder and it was right, but the odd thing or the temp sensor cannot repeat the same reading after a day or this damned station goes out of calibration after each turn off and turn on, today it was 30celsius less at 350 which im using the most i gonna check it with a ddm thermocouple soon and if it does the same error again like not heating up i will definetly force them to replace it

content: For info, I have three 'Hakko 191' units from China and all three are accurate to within less than +-1 degree Celsius of the readings provided by my lab grade thermocouples and Fluke Hydra. The 191 appears a decent thermometer and even reads the air temperature in my lab correctlyI still own the old Magnastat Weller soldering irons that have served me well for 20+ years. I would use nothing else 10 years ago. I have heard various stories regarding the modern Weller electronic irons so recently opted for a 'new old stock' PACE ST45 unit and a couple of lovely ST40A units. I already owned an HS200 preheater and MP1-E desoldering station. All the bits of PACE kit that I have are beautifully made and I am no longer fixed on Weller as a brand.Your unit appears to be suffering calibration data corruption which makes it totally untrustworthy in my opinion. Test kit and tools need to be trusted when carrying out electronic servicing or construction. If I were in your position, I would need a replacement new unit to restore any faith in the model and the brand. If a previous unit has failed in the same way think about a refund. As others have already said, it may be time to abandon Weller for another quality manufacturer.

content: Quote from: Aurora on December 06, 2011, 08:28:00 pmit was taken back to the shop to ship it to the local weller service center after a month with the issue of not heating up at all while displaying such a high value even the display turns off cos out of range, service center said to the shop owner it has no problem i took it back to home after a while i was checking for some reason at low temp i wonder why i couldnt set the lowest temp which is supported 50celsius cos it stucked at 100celsius as lowest and on this setting it was still melting the solder very quickly accorindig to the hakko unit it was 150celsius higher at 100celsius set on the station

content: Quote from: saturation on December 07, 2011, 12:53:20 pmthx i can calibrate it its pretty easy, it maybe have some memory issue in the controller, i gonna check it a few times when i do something and if its always gous out of cal everytime when i switch it off i would take it back to the shop once again, hell with the sales discounts....., wish i would had the money for the wr3000m kitdesoldering gun heat pencil and a 120w iron, but christ i just checked the prices on this and mine all of the weller product prices are 30% higher than before and almost 60% more then was the sales price

content: I don't know what the consumer law is like at your location but if an item misbehaves like your unit is doing, I would push very hard for a new unit rather than any sort of repair. In the UK, I can even engage the services of my credit card company if things turn nasty on the refund front.If you have a digital camera or web cam, use it to record the strange behaviour of your soldering station. A picture or video showing the soldering station and Hakko 191 temp displays would be good. Then show that evidence to the shop owner and request a replacement. I have successfully convinced shops and repair centres of intermittant faults in the past using digital camera evidence.I have an Audi A4 that created a really strange intermittent whirring noise under the bonnet from new....the Audi local garage checked it and claimed nothing was wrong with the car on three separate occasions. I then recorded the noise using the camcorder function of my digital camera, transferred the audi track to a CD and placed it in the cars Hi-Fi unit. The car was left with the dealer with the instruction to listen to the CD before starting work on the car. Surprise surprise, the mechanics looked a little deeper into the car this time and found that my Air Conditioning pump was faulty from new.....A GBP 1200 part that was just waiting to fail. Fixed under warranty :-)Its harder to brush off a customer when presented with video or audio evidence of an intermittent fault.

content: Quote from: Aurora on December 08, 2011, 04:00:18 pmyep thats true, i have 2 camcorder so the recording is not a problem, as far as i know they are forced to replace if the problem cannot be repaired or its not worth it if still under warranty, there is a 3 day replacemant or repay thing if the unit is faulty from the day you bought it but its long exceeded that time. i bought it in the first day of september so fairly new, unit is made in may according to the sn sticker on the unit
