Mig VS Stick Welding : Which Welding Process Is Best!
Stick welding does not require an external gas tank to supply the shielding gas. Instead the gas is created the flux coating burns. MIG welding does require a gas tank to provide the shielding gas. In MIG welding, a solid wire with no flux coating is used.
A short primer on welding equipment » DailyGrasp
Instead, the electrode is coated with flux which melts and covers the weld, shielding it from impurities. This flux shield has to be chipped off after the welding process is over. Because it does not require a shielding gas, stick electrodes are a cost-effective choice

Flux-cored wire is considered to have some advantages for outdoor welding on-site, as the shielding gas plume is less likely to be blown away in a wind than shield gas from a conventional nozzle.   A slight drawback is that, like SMAW (stick) welding, there may be some flux deposited over the weld bead, requiring more of a cleaning process between passes.
