Electrode Cigweld Cobalarc 750 Rutile type, AC/ DC hard surfacing electrode. Resistant to hard particle abrasion. Air hardening, crack free, martensitic steel deposit Easy arc starting and stable running on portable AC welding sets ( e 45 O.C.V.) . Developed in Australia Description and Applications: Cobalarc 750 is a NEW smooth running, rutile type electrode specifically designed for AC hard surfacing applications in the workshop or on the land. It gives smooth stable arcing on AC or DC welding machines and is particularly suitable for surfacing with portable AC welding sets ( with e 45 Open Circuit Volts) such as the CIGWELD Easywelder. Cobalarc 750 should be used with a touch welding or short arc technique and 1-2 layers are recommended for maximum deposit hardness. When hard surfacing high carbon or low alloy steel components a buffer or buttering layer of Ferrocraft 16TXP, 7016 or 7018 is recommended prior to depositing Cobalarc 750. Typical applications include the surfacing of agricultural equipment and components including points, shares, post hole augers, ripper teeth and tynes etc Typical all weld deposit analysis: C: 0.60% Mn: 0.46% Si: 0.75% Cr: 5.9% Mo: 0.40% Typical weld deposit hardness: HRC HV30 Single Layer on Mild Steel 64 800 Two Layers on Mild Steel* 62 750 * Not recommended for multi-pass welding heavier than 3 layers Contact Person : Sutrisno 08121026150
