The related a kind of permeability type shield structure with what electric welding grip device of this creation system comprising a shield unit, at least an air-flow guide unit, at least a telescopic unit. Shield unary system high-temperature-resistant structure, and a guard section and a fixed part are set, guard section has the semi open model working space of two openings of two openings and connection, and the ultraviolet light that can reduce electric welding irradiates shield unit. One of them opening of fixed part connection, stretches out another opening through open working space for electric welding gripping elements clamping welding rod and is welded. The air-flow that air-flow guide unit penetrates guard section and guides in semi open model working space releases； Telescopic unit links at least one position and angle for being open and adjusting electric welding field. Therefore this case has both can reduce uv damage and the advantages that angle adjustable can be carried out the electric welding of different angle.本創作係有關一種用於電焊握持裝置之透氣式護罩結構，其包括一護罩單元、至少一氣流導引單元、至少一伸縮單元。護罩單元係耐高温結構，並設一護罩部及一固定部，護罩部具有兩開口及連通兩開口之半開放式工作空間，可減少電焊之紫外線照射出護罩單元。固定部連通其中之一開口，供電焊握持元件夾持焊條經開放式工作空間伸出另一開口進行電焊。氣流導引單元穿透護罩部而導引半開放式工作空間內之氣流釋出；伸縮單元連結至少其中之一開口而調整電焊作業之位置與角度。故，本案兼具可減少紫外線傷害與可調角度能進行不同角度之電焊等優點。
