I just purchased the Dynasty Dx 200 , I wired it up to run 460 volts , my first time hearing this machine run , I think there is an electrical issue internal in this machine .it welds fine but, I hear an electrical arc not a fan but something of that nature when the machine is in Idle . Is this common....
I would expect to hear a fan , it just raises my concern there is something going on inside that is not right.
Any help would be appreciated

Ps : I don't feel the fan running
