Ok Jeff, I picked up a PRO300 earlier this year and put on the idle kit on it.

Now here is the problem, it idles fine with the ignition switch, rev's and idles when welding, now if you hit the grinder or plug anything in to the 120 or 240 side the machine will not pickup on its own? It puts out 240/120 at 50HZ as the manual says to set the idle speed at.

So I guess is this the way that the PRO is or is there something wrong ?

Thx Railmen.
