What is an advantage of an inverter welder over a transformer-based welder?

Use extreme caution when working with high frequency circuits because:

Which is NOT a factor to consider when wiring a power unit to an electrical source?

Correctly identify the part indicated by the arrow in the figure below.

Dust and dirt need to be periodically removed from the following parts of a welding power source?

A given static load on a weldment will not cause failure of the weld.

An increase in dust and dirt within the welding transformer will effectively its duty cycle.

The presence of dust and dirt within the spark gap will the voltage required to jump the gap.

According to the American Society of Mechanical Engineers (ASME), the highest percentage of welding defect causes are:

Burn-through can result from poor joint fit-up.
