Trying to decide whether to purchase a new 200dx or a used 300dx. What are the major differences between the two besides the obvious amperage
capabilities. In doing research I see that the new 350's have quite a few more wave pattern adjustments then the 200. Do the 300's have these same capabilties like the new 350's? I really do not need the amperage capabilities of the 300, but I do do alot of lighter gauge aluminum and the it seems the ability to fine tune that arc would come in handy in that respect. I guess my question goes out to the users out there who have real experience with both of these machines. Do you really use the added capabilities of the 300-350 enough to justify the added cost? Thanks in advance for any information. It is appreciated. Mike
