Question

the operator can control amperage by turning a dial on the _______ or the _______. (select two.)

electrode holder
power source
remote control (if equipped)
feeder (if equipped)

Explanation:

Analyze the question prompt

The question asks how an operator can control amperage by turning a dial on two specific components: "The operator can control amperage by turning a dial on the ______ or the ______. (Select two.)"

Evaluate the options

Using the Welding Power Sources and Welding Remote Controls knowledge points, we analyze the four choices:

• Electrode Holder: This is a passive clamping device used in SMAW (stick welding) to hold the electrode and conduct current. It does not have a dial to control the machine's amperage.
• Power source: The main welding power supply unit has a control panel with an amperage adjustment dial to set the output current directly.
• Remote Control (if equipped): Handheld or foot-pedal remote controls allow the operator to adjust the amperage dial from a distance without returning to the power source.
• Feeder (if equipped): A wire feeder is used in GMAW/FCAW to control wire feed speed (which indirectly influences amperage in CV welding), but direct amperage dials are typically on the power source or dedicated remote controls.

Select the correct answers

The two primary components where an operator directly turns a dial to control amperage are the Power source and the Remote Control (if equipped).

Answer:

• Electrode Holder
• Power source (Correct answer)
• Remote Control (if equipped) (Correct answer)
• Feeder (if equipped)
