MIG Welding

what is mig welding?

Gas Metal Arc Welding process (GMAW), commonly known as Metal Inert Gas process (MIG) welding, is an arc welding process that establishes an electric arc between the work piece and a consumable bare wire electrode; where the arc continuously melts the wire as it is fed into the weld puddle.

MIG welding is suitable for a variety of applications - from small body shop repairs to large fabrications - and at ARCO Welding Supply in Malden, Mass, we have serviced professional welders throughout the New England area since 1950. Over the years, we have built a solid reputation as a leading MIG welding supply distributor who consistently provides exceptional customer service and offers a wide selection of quality Mig welding supplies and equipment from the industry's leading manufactures.
