In a DC machine, the function of the yoke, or frame, is to provide structural support and house the magnetic components. It serves as a pathway for the magnetic flux generated by the field windings, ensuring efficient magnetic circuit continuity. Additionally, the yoke protects the internal components from environmental factors and mechanical damage. It is typically made of ferromagnetic material to enhance its magnetic properties.

A standard GFCI (Ground Fault Circuit Interrupter) is typically designed for AC circuits and may not function properly with a DC welding machine receptacle. GFCIs detect ground faults by monitoring the current imbalance between the hot and neutral wires, which is different in DC systems. Therefore, using a standard GFCI for a DC welding machine could lead to nuisance tripping or failure to trip when needed. It's essential to use a GFCI specifically rated for DC applications if required for safety.
