Need Help Soldering	Reply
by KD8ERE on July 2, 2009	Mail this to a friend!
A short while ago, there was a topic on here regarding solderless PL259 connectors, and how well they worked. While I usually prefer them, I'm thinking it's about time to swallor my pride, and ask for some help. I've only ever been able to solder something such as copper pipe together. Something as small as a PL259 connector has always given me problems. How to I properly solder coax to a 259 male connector? Please help! 73s, Ryan KD8ERE

Go to the Elmers forum and type "Soldering PL259" in the search box. You'll find more than a dozen hits on this topic. Some hints work FB for me, others not so good for me. However, you may find a hint or two that will work well for you. I'd recommend a true silver-plated brass connector with phenolic or teflon insulation. I've found that reaming out the solder holes to make them a little larger exposes more brass metal, and makes the metal easier to solder. I also use a Weller soldering gun without the heating element; I just put the two element rods against the connector, pull the trigger, and in a few seconds the connector is hot enough to flow solder for a good, solid connection.

Thanks for your help. I never thought to look on the Elmers forum.

W5FYI: That is great advice and thanks. I have always had trouble soldering the braid and while I've used the soldering gun method you mention I didn't think to file or drill to expose the brass. 73.

Properly soldering connectors on coax is a fine art that requires certain tools to accomplish. The art is basicly patience, dont be in a hurry, do it right, take your time. The TOOL is a soldering iron with a lot of heat reserve that gets hot enough to quickly solder without causing massive melting if coax plastics. For such a soldering iron go to the 'American Beauty' web site and check out their high wattage soldering irons--at the very last 200 watts.

hi, a weller sp-100, sp-120 and the american beauty irons are the difference between a heat source and a heat sink when you try to use lesser wattage irons. 73 james

There are three basic rules to successful soldering: 1- It has to be clean 2- It has to be clean 3- It has to be clean.

I now use a little Weller torch to heat the connectors. Practice on a used one first. Plenty of heat on tap and no AC required. Unless you are using asilver plated connector exposing the brass is a good idea.
