moulding holes--How to weld

if its a trim moulding hole then its not that big ....I tried getting behind the holes and you just cant unless you have two people on it and even then.

I ended up just putting the mig wire across the hole and arcing it easy ....and made what looked like cross hairs with the mig wire by just arcing the wire across the hole, then filled it in by pushing the molten puddle to the hole edge ...didn't really need to get behind it and after grinding and sanding, cant even tell it was ever there.


main thing is patience ...each hole is going to take awhile if you want to minimize warping and get it filled in complete
