Hello again Dark_Angel, I believe that machines such as yours are capable of running the "same" amperage while in a different range, yet doing this will affect how the voltage interacts relative to the amperage and thus you can experience a "stiffer" arc while in one range and a "runnier" puddle while in another range at the same amperage. Other machine types provide this sort of thing by use of arc force, inductance, or other similarly titled controls. Hope that makes sense. If you read through many of the postings about the SA 200's you'll see topics about rolling the "rack" (referring to the brushes) and other such items that pipe liners and pipe welders have discussed at length and the benefits that can come from some of these abilities. Good luck and best regards, Allan
Well, I was positive I posted here earlier today. Cyberspace gets another wayward post.
So, I'm confused..."Gears"?? on a 200D? 3rd, 4th? Not sure I understand what you are asking. I have not had a Lincoln or Miller portable with gears.
You wouldn't want to change polarity while welding, if you have that option. But what else is there on the 200D that could be damaged by switching during welding? While I never change anything during welding there are not many things that can be damaged by doing so.
He Is In Control, Have a Great Day, Brent
