1 N94 W14355 Garwin Mace Dr. Menomonee Falls, WI 53051 262-532-4677 800-558-8524 6/9/14 mg 540 All position, controlled hydrogen electrode for structural and mild steels GENERAL CHARACTERISTICS: mg 540 is a premium quality, high strength, all position electrode featuring low-amperage requirements and fast, easy deposition. Deposits of mg 540 are ductile and dense for x-ray quality joints in crack sensitive steels. APPLICATIONS: Construction of structures for H to I beams, angle and channel iron, pipe, tube, flat or round mill stock and joints subject to comparatively high stress situations. TECHNICAL DATA: Typical Tensile Strength Up to 80,000 psi (56 kg/mm2) Polarity AC or DC reverse (electrode +) Diameter Amperage 3/32 ( ) 60-100 1/8 ( ) 110-150 5/32 ( ) 140-200 3/16 ( ) 220-280 PROCEDURE: Area to be welded should be cleaned thoroughly. Surface contamination must be removed and beveled or chamfered where required.
2 Maintain close arc length. Vertical joints should be welded from bottom up, using rapid weave technique. Do not whip. Use drag technique to make horizontal fillet welds. Slag is easily removed.
