I'm looking into a plasma cutter for light use. Occasional use only and I have a Lincoln Mig and Stick ac/dc welder. I think one of the small units will work and am looking at an Amico and Lotus brand. A lot is said about the quick start...or other term and this is only with the Lotus which is about twice the price. Shopping at Home Depot but can also consider online. Any inputs...is the auto arc a considerable factor. Looks like the Amico works well per the Utube videos....
