Questions and Answers

What does welding amperage refer to in a welding circuit?

The distance from the end of the contact tip to the base material

The amount and speed of electricity flowing in a circuit (correct)

The arc length in combination with the stick-out

The speed and volume of filler metal going into the weld

How does welding amperage affect weld penetration?

Higher amperage settings yield greater joint penetration (correct)

Higher amperage settings provide less joint penetration

Lower amperage settings have no effect on joint penetration

Lower amperage settings yield greater joint penetration

How does increasing the welding voltage affect stick-out and amperage?

Increasing the welding voltage increases stick-out and decreases amperage.

Increasing the welding voltage decreases stick-out and increases amperage. (correct)

Increasing the welding voltage has no effect on stick-out and amperage.

Increasing the welding voltage increases stick-out and also increases amperage.
