Abstract

PURPOSE: To avoid a defect in welding by preventing the function of an electromagnetic gas valve from deteriorating, by providing a gas filter at the gas inflow side of an electromagnetic valve for shielded gas control in a gas shielded arc welder.
CONSTITUTION: At the gas inflow side and outflow side of electromagnetic gas valve 7, gas inflow side metal fitting 22 with gas intake 22a and gas outflow side metal fitting 23 with gas outlet 23a are arranged. Then, the side plate of housing 8 is interposed between collar 22b of metal fitting 22 and nut 24 to fit valve 7 to housing 8, and rubber tube 9 is provided around metal fitting 23. Next, gas filter 25 in the shape of a cone or cone frustum is fixed in gas intake 22a with O ring 26. Consequently, iron powder, etc. deposited sticking to the metal fittings and in the gas passage of the rubber tube near them is collected by filter 25 to prevent the function of valve 7 from deteriorating.
