I had a co-worker ask if I could weld with a few solar panels. Figured with some 395 Watt panels laying around I should try and see. Did some research and found that DC Arc welding works in the 50VDC range and needs 20-150 amps depending on the situation. Each of these panels are rated at 49 Volts open circuit and about 10 amps a piece. I figure a few in parallel could work, and in this video we find out for sure!
