Spoolarc 29S is a general purpose wire suitable for many MIG and submerged arc carbon steel welding applications. Suitable for use over light rust.
Spoolarc 29S is a general purpose copper-coated solid wire suitable for many carbon steel welding applications using either the MIG/Gas Metal Arc Welding (GMAW) or the Submerged Arc Welding (SAW) processes. Spoolarc 29S contains moderate amounts of manganese and silicon to provide sufficient deoxidation over light mill scale. Shielding gas choices for Spoolarc 29S in the GMAW mode are 100% carbon dioxide, argon/carbon dioxide mixtures, argon/oxygen mixtures, and other argon based mixed gas blends. In the SAW mode, Spoolarc 29S can be combined with a variety of active and neutral bonded fluxes to achieve better welding performance over Spoolarc 81 wire. Spoolarc 29S is used in a wide variety of applications including heavy equipment, automotive parts, railcars, agricultural equipment, and sheet metal welding.
