Butt or fillet MAG welding of structures such as vehicles, and industrial machinery.

Characteristics on usage:

MG-51T is a solie wire which is designed to get good usability in all-position welding of steel sheets by the short-circuiting arc with CO² gas or Ar + CO² gas mixture for shielding. The arc stability is good in the wide range of welding currents.

Higher current can be applied in vertical and overhead positions as compared with MG-50T. It is suitable for all-position welding of pipes. The well-adhered copper plating without flakes and without rusting in long duration storage, glossy wire surface by the special treatment, well-controlled cast and helix to make accurate tracking on the weld seam, rigid spool to prevent insertion of wire into the underlayer wire; these features assure smooth feeding of wire with stable arc; regular beads and higher efficiency in welding.

Notes on usage:

1. Use CO² gas equivalent to JIS K 1106 Gr 3 or CO² gas purified shielding in welding.

2. It is very important to control mixture ratio when mixing gas of Ar + CO² is used because the fluctuation of mixture ratio may affect adversely on usability.

3. It is suitable to use shielding gas of 20 to 25 l/min.
