I have a Linclon 125 flux core welder, the same Lincoln with a bottle, and a bigger Miller 175 with a bottle. The flux core welder sees almost all of the work. I use it for everything from sheet metal to roll cages. Took it to fix a dump truck body once, and use it on job sites to weld plates to lally columns. I like the fact that it plugs in to any 110 outlet and I can carry it in the back seat of my truck. I've let just about every friend I have borrow it, and it just keeps on going. It's an easy machine to learn on. Bottles make it nice, but not really required for what us Brit car guys want to do.
