In incandescent loads wattage affects heat. We can have a 100 watt light bulb at 12 volts 8.3333 amps, another bulb might be 120 volts, .8333 amps Their light output and wattage would be equal.

I believe a flat weld can be near equal with 20 volts, 200 amps as it would at 80 volts, 50 amps. Wattage is equal

I'm not clear about the science of having an easier time weaving uphill with lower voltage/higher amperage. Can anyone enlighten me?

An optimist is usually wrong, and when the unexpected happens is unprepared. A pessimist is usually right, when wrong, is delighted, and well prepared.
