Hello All,
I have a pair of R4C's and an R4B that will get new electrolytics. They are
stock at present. First job is removing the old cans. All I have is a Weller
gun at present100/140 for the removal. I have a standard iron for installation.
If anyone can suggest the best way to remove this
Don,
I couldn't get my 100/140 gun to do much more than move the solder around a bit
on the chassis. I had the same trouble on my outside antenna wires, so I
treated myself to a new 200/260 Weller, and it WILL do the job, hi. Others
recommend the huge irons, but I went the bigger gun route as
Don's - I was surprised recently as well when using my Weller 100/140 gun to
reattach the power switch leads on my L-4Bthe gun just wouldn't get hot
enough to make a good solder joint. For grins I fired up my Weller soldering
station and popped one of the larger size tips in, set it for
You might start out with a solder sucker and then sop most of the rest with a
solder wick which I have made from the braid of coax.

Hello All,

I'll try my Weller WTCPN station on more after that remark, Dino!! However, I
did try it on those can tabs in desperation, and even with an 800 degree tip,

The thing I have learned about guns is that it's a good idea to re-snug the
connections (nuts or setscrews) at the tip before each use for best results.
Guns don't have a lot of thermal mass at the tip, so it also helps to use the
two-handed approach - supplement the heat from the gun tip with
Since i don't have a solder sucker, I first used solder wick with a
Weller 100/140W gun to remove as much as possible, then I used a Dremel
to grind away enough of the tab to break it. I kept a shop vacuum hose
in there to catch the filings. The solder wick step might not have been
needed.

See my comment about re-snugging the tip connections :)

Soak the braid in rosin flux first, that helps.

That's my home gear, a WTCPN!
