Thanks to all,

i will try monitoring the power line and MCLR to see if something strange will appear also if without the cap seems to work fine and seem also to be insensitive to noise.

about PIC programming.... oscillator XT all aother flags OFF.

This week the hardware and firmware will be extensively tested
on a induction welding machine in a very electrically noisy environment

AC and DC line will be monitorized...

When the gremlins will be found i will post his head in the forum!
