WHAT IS THE BEST SHIELDING GAS FOR MIG WELDING?MIG welding with shielding gas and a solid wire electrode produces a clean, slag-free weld without the need to continually stop welding to replace the electrode, as in stick welding. Increased productivity and reduced clean-up are just two of the benefits possible with this process. The primary purpose of shielding gas is to prevent exposure of the molten weld pool to oxygen, nitrogen, and hydrogen contained in the atmosphere. The re …
