Typically, the best welders are the ones that have all three welding processes: Stick, MIG, and TIG.
The number of features and types of welding processes varies depending on your needs and budget.
If you're willing to spend a little more money than some very good multiprocessing welders, include:
LOTOS CT520D, FORNEY Easy Weld 140 MP, SÜA IONMIG 200 MULTIPROCESS WELDER, EVERLAST POWERMTS, LINCOLN ELECTRIC POWER MIG, ESAB REBEL EMP215IC PROFESSIONAL-GRADE WELDER.
