Hi,
A friend of mine has a soldering station similar to this:http://uk.farnell.com/weller/wr-3000m-uk-eu/desoldering-station-420w-230v/dp/1582381
I would like one but they are out of my league. I did buy a tip though to see if I could get it to work: http://uk.farnell.com/weller/rt2/tip-soldering-iron-needle-0-8mm/dp/8809879?CMP=i-bf9f-00001000
These are temperature controlled, so I assume there is a heating element and a sensor inside the tip. As you can see there are three points of connection. I checked the resistance at the jack plug: large contact GROUND to RING = 1.1 Ohm cold. GROUND to TIP = 1.9 Ohm cold. RING to TIP = 3.0 Ohm cold. GROUND to RING = 6.3 Ohm hot. GROUND to TIP = 0.0 Ohm hot. RING to TIP = 5.6 Ohm hot.
I need to know which is the heating element and which is the sensor. First I will try voltages 12 to 24 volts, then perhaps I will make a sensor controlled power supply.
Any help in getting it to work would be helpful please.
