ABSTRACT:
An idle solenoid assembly sets the idle speed of the internal combustion engine of a self-contained welding machine. The idle solenoid assembly comprises a bracket to which a solenoid is immovably secured. The solenoid plunger is connected to the engine governor arm. The bracket has slotted feet that slide on an engine surface. By sliding the bracket, the position of the engine governor arm is adjusted to produce the desired engine idle speed when the solenoid is actuated. There is no contact or binding between the bracket and the solenoid plunger or between the solenoid plunger and the engine governor arm. The solenoid is wired to a control circuit through a first plug retained in the bracket and a second plug. The solenoid is properly grounded on the internal combustion engine through the second plug.
