WELDING INSTRUCTION
PREPARE THE METAL
Metal must be completely clean and free from rust or paint before welding. It is
difficult to arc against a dirty surface, but any contaminants will find their way
into the weld and reduce its strength. Light use of an angle grinder or flap
wheel will quickly remove surface rust and paint. For more inaccessible areas
an air grinder or dremmel can b e effective.
• M.I.G. OR STICK - 5/32˝ fillet weld minimum.
• M.I.G. WELDING - Use A.W.S. ER 70S-3 or 6 wire or equivalent with a
diameter of .035 - .045. The recommended shielding gas mixture is
75% - 95% Argon & 25% - 5% CO
