What is the purpose

[Revlimit]

I agree, the 350P is a profit maker. The speed, precision and quality this machine allows me when welding 1" square tube (0.65 wall) aluminum is unmatched by any other process I've used. Tig can't touch it in terms of small bead size. This machine has more than doubled production in the shop. That's the bottom line unless you are doing it for fun.
