We,ve had this problem and have done a lot to correct it. We mainly experience this on new saws we have gone to a high impact brazing tip and virtually eliminated the problem. But we still take a piece of hard neoprene stick (sort of like a club) and hit the tips so as not to send any bad saws to the customer. If you knock any out put them back in and you are okay.

I believe the problem is the the plate has not been tempered yet and it expands and contracts so much more the first time you apply heat. The tip cools down first then the plate cools and shrinks back down pulling on the tip causing stress cracks
