MIG / SMIG

MIG/Gas Metal Arc Welding (GMAW) — MIG welders use a wire welding electrode on a spool fed automatically at a constant pre-selected speed. The arc, created by an electrical current between the base metal and the wire, melts the wire and joins it with the base, producing a high-strength weld with great appearance and little need for cleaning. MIG welding is clean and easy and can be used on thin or thick metals.
