Question What soldering gun wattage is needed for metal chassis soldering/desoldering?

I haven't done too much old tv restoration and I'm running into a problem. I don't have anything heavy enough to unsolder the filter caps from the chassis for restuffing. My old weller 100/140 watt gun won't cut the mustard. I bought a gun I thought would do it from Sears a Craftsman 400/150 watt that heats the tip up with 400 and maintains at 150 watt.I'm taking it back. It won't cut the mustard either.

They have a dual wattage one with 250 watt when held in the 2nd position. Looks just like the Weller version. Is that enough?Or do I need to find a butane torch or one of those huge old soldering irons they don't make anymore for this job?...lol.

They must have had something pretty heavy back when they made these sets with metal chassis. The Admiral Super Cascode I'm working on has all 4 twist leads of the caps directly soldered to the chassis also all the terminal strips
