Zusammenfassung:	PURPOSE:To provide a low hydrogen type coated electrode having excellent arc stability and short resistance in a low current region. CONSTITUTION:This low hydrogen type coated electrode is formed by coating the outer periphery of an iron core wire with a coating material which contains, by weight % of the coating material, 25 to 55% lime carbonate, 5 to 24% fluorite, 2 to 9% rutile, 1 to 5% Mn and/or Mn alloy (in terms of Mn) and 2 to 8% Si and/or Si alloy (in terms of Si) and contains =125mum. The content of mica is preferably suppressed to
