Solder?
« on: February 04, 2017, 02:52:38 pm »
I am attempting to change the power cord on a TW transformer.  To get to the terminals I will have to remove a bracket above it which requires disconnecting a couple of wires.  I first tried to heat the solder with a pen and then a Weller 8200  100-140 watt gun.  I still have not melted the solder to break the connection.  How much power does it take?  The tip on the gun has been cleaned and re-tinned for proper heat transfer. I get a little smoke but, no melting.  Do I need more power? Thanks!

You need more heat than your 140 watt gun can deliver. A 260 watt gun like the Weller D550 http://www.weller-toolsus.com/soldering/guns/weller-d550-gun-soldering-professional-d550.html is what you need for those heavy terminals and wire.

I was afraid that was the problem.........  Now the search is on!  I know they made a higher wattage D550 in the past.  I will see if I can find one of those.  I was hoping it was just my ignorance! Thank you for your knowledge and kind response.
