[QUOTE="Blackleg, post: 1109820, member: 5617"] Are you getting confused with "Inductance" OCV Open Circuit Voltage is the voltage present before the arc is struck, once you strike the arc and commence welding there is no OCV because it's not an open circuit. When the arc is struck you then get your welding parameters typically 18-26 volts for dip transfer and 26 volts plus when in spray (off the top of my head when running 1mm wire). The only time OCV can be problematic to a welder is when stick welding, it can be hard to strike an arc with some cellulosic electrodes with a low OCV. No it doesn't, the MIG process is constant voltage i.e. the "self adjusting arc". That would be true if you were stick welding as it's a constant current power source. I think you're getting muddled up again, here's a link so you can learn some stuff.

My local suppliers sell Binzel torches and associated bits at really good prices so I'll stick with what I've got because it's also good kit. I told you, read my post.
