I understand what they mean and kinda how the voltage works. However the other day the wrong welding truck was taken out to me, cv does not work on this machine. No rod on the truck, and I had a ton of welding to complete. I'm using 045 212 innershield. I played with the heat on regular cc welding, suitcase was set on cc, running around 100 amps with wire speed set around 260-280, I finally got it welding good. It was making some decent looking welds. I know quite is designed to wells on cv voltage. Thoughts and opinions? Educate me
