the advantage of a DC machine, especially an engine driven one like the SA200 Lincoln Pipeliner is the abiltity to use High Amperage and Low Open Circuit Voltage or Low Amperage and High Open Circuit Voltage to get basically the same heat, but with completely different Arc Characteristics.
And Arc Blow is not that big a problem, any old time welder usually knows how to counteract it. see http://www.iforgeiron.com/forum/f64/...-welding-4398/ post #15
