MIG and flux-cored welding offer advantages over other welding processes, especially for the novice. With these two processes, the welding machine creates an arc between the work piece (what you want to weld) and a continuously consumable electrode (the “wire” in these wire welding processes). The operator need only focus on directing the MIG gun at the joint and proper motion. Most welding machines that can MIG weld can also flux-cored weld.
