Welding device of consumable electrodes of electric slag furnace and welding hand

The invention relates to a welding device of consumable electrodes of an electric slag furnace and a welding hand. The welding device comprises the welding hand, an automatic welding handle and a welding tool. The welding tool comprises a consumable electrode welding platform, a fixing mechanism, a rotation support, a rotation support mounting pier, a small gear and a speed reduction machine; the welding hand comprises a motor transmission part, a welding handle position manual lifting part, a welding handle position horizontal adjusting part and a stand column; through the welding hand with a control plate position capable of being freely adjusted in the vertical and horizontal direction, through cooperation of the automatically rotating consumable electrode welding platform, the automatic welding handle does not move, a consumable electrode mother material is dragged to be rotatably welded through the consumable electrode welding platform, and therefore labor intensity of welding persons can be greatly reli
