Question

the power company supplies what type of voltage input to the welding machine?
primary voltage
the heat
secondary power
juice

Explanation:

Identify the input power source

Welding machines require an external electrical supply to operate. The power company provides this incoming electrical energy directly to the machine's input side.

Define primary voltage

The incoming power from the utility line is called the primary voltage (or input voltage). This is typically high-voltage alternating current (such as 110V, 220V, or 460V) that the welding power source will step down and convert for welding.

Define secondary voltage

The welding machine's internal transformer converts the high-voltage, low-amperage primary power into a safer, usable low-voltage, high-amperage output. This output power used for the actual welding arc is known as secondary voltage (or output power).

Evaluate the given options

• Primary voltage: This is the correct term for the incoming voltage supplied by the power company.
• The heat: This is a thermal byproduct of the welding arc, not an electrical input type.
• Secondary power: This is the transformed output power generated by the machine itself.
• Juice: This is an informal slang term, not a technical classification.

Select the correct option

The power company supplies primary voltage to the welding machine.

Answer:

• (A) Primary voltage (Correct answer)
• (B) The heat
• (C) Secondary power
• (D) Juice
