PROBLEM TO BE SOLVED: To obtain an electric arc thermal spraying device by which thermal spraying wire rods can smoothly be fed even without using a motor having a high driving force. SOLUTION: The space between wire rod feeding apparatus 2, 2' feeding two thermal spraying wire rods 1, 1' and a thermal spraying gun 4 having a first driving part 5 performing the feed of respective thermal spraying wire rods 1, 1' is provided with second driving parts 6, 6'. The second driving parts 6, 6' give wire rod feeding force which does not exceed friction resistance acted on the respective thermal spraying wire rods 1, 1' mainly passing through the insides of guide tubes 7, 7' to the respective thermal spraying wire rods 1, 1'. |
