Red Seal Welding Practice Exam

Question: 1 / 400

What's the first step when changing an empty spool of wire?

Clean the gun nozzle

Turn the machine off

The first step when changing an empty spool of wire is to turn the machine off. This ensures that the machine is not powered and reduces the risk of injury while replacing the spool. Option A, cleaning the gun nozzle, is not the first step as it requires the machine to be turned off first. Option C, pulling the trigger, is also incorrect because it can cause unplanned wire feeding and may create safety hazards. Option D, checking the wire tension, can be done after the machine is turned off and the new spool is properly loaded. Therefore, the correct answer is to turn the machine off first.
