Primary electric shocks come from a welding machine's internal wiring and are usually more dangerous than secondary electric shocks. You can receive a primary electric shock from:

• A. From touching electrically hot components inside a welding machine or welding device lead
• B. From touching a grounded clamp
• C. From standing near the machine
• D. From inhaling welding fumes

Answer: (A)

Primary shocks come from energized parts within the welding power source or the wires that deliver the welding current. They can be more dangerous because they involve higher voltages directly from the power supply. You would receive a primary electric shock by touching electrically hot components inside the welding machine or the device leads that carry live voltage. A grounded clamp sits at earth potential and does not pose a primary shock hazard by itself. Merely standing near the machine or inhaling welding fumes are hazards, but not electrical shocks.
