Broken Jack/Power Socket

[SonPregioo]

Hi guys,
I had problem with my power socket on my HP 550. The "needle" was very loose and it was overheating, so I ordered one online, it arrived and was ok. Now I took off the old power socket but its "teeths" remained inside the holes of the motherboard. I 'm trying with the welder but I m scared that I could ruin the motherboard. I uploaded Pics.

Any help pleasee!?

Thank you very much, you've always been of help.

Normally you don't break those off. I would use a solderiron with some solder wick until I can work them free enough to remove them with tweezers.
