If you needed to use 2 power sources for welding, how would you use them?

Parallel hook up
Series hook up
Alternating hook up
Independent hook up

The correct answer is: Parallel hook up

A parallel hook up would be the correct option because when using multiple power sources for welding, you would want them to work together. Hooking them up parallel means the voltage remains the same while the current is shared between them. This prevents the power sources from being overloaded or producing inconsistent voltage, which can lead to poor welding results or damage to the welding equipment. Series hook up (Option B) would result in voltage dropping and current increasing with each additional power source, making it unsuitable for welding. Alternating hook up (Option C) would alternate between the power sources, which would be inefficient and produce inconsistent results. Independent hook up (Option D) would mean using the power sources independently of each other, which defeats the purpose of using multiple power sources.
