Parameters in the welding need to be known because the effect on the mechanical properties of the material after the welding process. This research purposes to find out the influence of variation of SMAW welding current on Stainless Steel AISI 304, with variation of electric current equal to 70A, 80A and 90A.The electrode of AWS A5.4 E308-16 with diameter of 2.6 mm is used. Dye penetrant test, tensile test and metallographic test applied to analysis the characteristic. Based on data from tensile test results obtained the highest value on the specimen welding current 90A is equal to 632 MPa. The lowest tensile strength value recorded on the specimens of current 70A is 498.66 MPa.
