the thunderbolt of old was a great little machine. when i welded off a hanging wire rope scaffold i had a top crank thunderbolt on the platform. the welding leads were pretty short but the power cable could be 200 feet or more. iirc i don't recall the d.c. being an issue. i was more worried about my electrode touching the 5/16" cable than duty cycle.
