MIG gear is affordable enough now to be within reach of the hobbyist, with this Campbell Hausfeld unit from Harbor Freight Tools priced under $400. Make sure to step up to a gas-bottle system rather than the gasless flux core wire, since the latter will leave flux in and on the weld. The auto-darkening helmet, also from Harbor Freight, is a significant step to welding ease and worth every penny.
