Apologies, I miss read that you were using 2 at once.

1 grinder on a 3.5KVA genny should be no issue.

Have you tested the voltage the generator is outputting?

If it's not quite 110v and more like 90v the current will increase in the grinder an it also will not run up to full speed. Or the other way the voltage is to high and the insulation is becoming damaged in the grinder.

HMCIVAL I'm trying to tell you mitike grinder is a nice grinder and think about it 2 brand new grinders have burnt up and you talking about you are using old generators. It needs earth bonding or the regulator is bad in the generator. Instead of buying grinders and buy a new generator

We have a old bosch grinder that runs fine on all are gennys and our smaller hammer drills small electric breaker also works fine

I'm still wondering if its a feature of how big a Kick ,you get when first spinning the disk up.
Is it a normal cutting disk ,or something more fancy ?
(a mix of Genny trying hard/stutter? ,
No slow start on grinder + Disk heavy on outside edge )

I told him that but he disagreed, it has to be the generator
