I wanted to try my luck at re-stuffing a can Capacitor, I m having a heck of a time removing the solder from the ground from the can to chassis. I know its sucking up all the heat.. I only have 2 irons, a station that's fine for most and a Weller D550 240/325 watt gun.
any advise?

Tip size and mass more important than wattage. 3/8 to 1/2 inch or wider.
Weller has an 80 watt pencil with wide tip fairly easy to find in hardware stores.

The D550 should handle that, are the nuts tight on the tip.

Try adding flux if you have some, or solder (with a flux core). Solder-wick or a bulb to remove the solder as you go.

when I am stuck, judicious use of a micro-butane torch...but one has to be very careful....

Yes. I have irons from 40 to 200 watts. Most of the time the 40 watt Weller (1/4" tip) will do anything I need it to. For the few times it isn't enough the 100 watt with 1/2" tip comes out. I can't remember when the 200 watt was last out of the tool box.

The D-550 might be messing with you. Pretending to heat but not so much
because the tip fasteners need re torquing. Also to get the lugs unsoldered,
feed more solder to build a heat bridge right down to the chassis.

thanks, between tightening the tip and adding solder, works much better

I have 2 irons, an Harko FX888D and a Weller WE1010.

Although good equipment, they are not up to the task for soldering/desoldering caps can or chassis ground.

I was getting crazy trying, and damaged some tips doing so.

I finally bought a Industrial Weller D650 heat gun. 200W/300W powers how you press the trigger.

I now can do this task in literally 10 seconds. That gun heat up in 6 seconds and it up to any task thereafter. I am so happy with it, even if the bogus lights never worked on it.

And if fact you don't heat up at all the can: it remains cold as the soldering process is so fast.
I even used it on pure silver #14 ground bus and it worked nicely. With my regular iron it wasn't easy.

My 2 cents.
Brice.

Just an alternative- drill a hole in the chassis and screw/nut down a solder lug. Or another was is to find the nearest place on the chassis that has some sort of wire/ground connection and install a new wire to that point. Either way will save a lot of frustrating work.

We used to un solder/solder grounds in a shop by one tech calling for
other techs to bring their irons over. Then 3 soldering irons were applied.

As boss tech I remembered growling them back if a chin-wag started.

In my next career, our boss did exactly the same when a gaggle of
electricians were at the 'print' table discussing a drive.

Some of the prints folded out to be ten feet long. (substation metallic switch
gear cubicles.)

If there is significant corrosion, cleaning with a wire brush, steel wool, or a very fine file prior to applying flux or solder makes the job much easier.

I second tight nuts. I had the same problem. tightened the tip and huge difference. Also remembered that on my Weller gun the trigger has two positions. About half pull gives the most heat and full pull gives less. Doc

Well that helped Doc... Thanks
I thought the high setting was the trigger puller all the way back... But I also found the tip connection loose and corroded. I have the old original D550, it has a higher wattage
