content: what is a good solder fan diagram. I using a power pack 12v 100ma and 120mm fan 12v.

content: Quote from: odell on March 20, 2012, 07:38:51 amI'm not sure what that isIf you want to run the fan then...- Check your 12V 100mA power pack to make sure it's DC.- Read the writing on your 12V fan and check the current needed is less than 0.1A (100mA). If the fan only has a wattage then divide the wattage by 12 to get its required current)- Connect the positive wire on the powerpack to the red (positive) fan wire.- Connect the negative wire on the powerpack to the black (negative) fan wire.The negative/positive wires on the power pack may not be marked so you might need a multimeter.

content: Some time i built myself one ... Wasn't the best looking as it was out of cardboard , and stiffened extremely with the overindulgence in hot glue and lots of cloth tape .A simple connection to the fan is enough , unlike my overcomplicated PWM controlled dual fan push pull setup .Oh i thrashed it long time ago , was taking up space i.e no space for my 2nd soldering station and i didn't need it anymore . ( Filter completely blocked)

content: ...or, you could roll your own, e.g.this instructable. (I think there are some pretty "altoids" style ones around as well)Actually, I'd be interested to know how much these are just marketing gimmicks. Was talking to a lung doctor the other day about this and he hadn't ever heard of any issues with solder fumes in over 30 years of practice.

content: Yeah, I just use my magnifying lamp as a shield and breathe out when I see smoke.

content: I use this $9.99 AC fan to just gently blow across my solder area so the smoke does not rise up in my face or into the microscope. It never gets dirty because it is blowing not sucking. This one came from Target and was sold for college dormitory use. It has an on/off switch in the back.

content: Quote from: harnon on March 20, 2012, 05:14:40 pmThis is no gimmick. Where you are located might not be enough cases of health issues caused by soldering fumes. Have a look at what the MSDS of the solder wire says about the fumes. If you work in an assembly plant where some parts has to be manually soldered then you are exposed to such risk, if there is no adequate ventilation. I am lucky enough to know a few doctors as close friends and most of them insist that I do lung function test(because it's simple) every 6 months to track condition of my lung. That is if you do soldering 3-5 hours a day.Blowing works better most of the time but the room need to be ventilated. Sucking fan with filters are better for small room with little ventilation.

content: I have looked at a few MSDS and most list things like nausea as the main possible side effect.This random onedoes warn of possible asthma from prolonged exposure but there are many things which can "encourage" asthma!Im not saying don't bother, as you only get one set of lungs (and for all i inow lead based ones are far worse), but if for instance you are a smoker, welder or carpenter cutting up MDF etc, then you probably have more important things to worry about than a few solder fumes.

content: Lead-based solder doesn't increase the toxicity of the fumes because soldering temperature is not high enough to vaporise lead. The fumes are from the rosin.

content: People should really know it for years .If lead gassed off ,the tin in solderswould also have gassed off .And if they gas off , you are doing something VERY wrong . When they gas off you know what i mean , your solder is not a solder anymore , you have nothing left !
