MIG Welding Wire, ER309LSI Stainless Steel, 0.035", 11 lb. Spool
Details
ER309LSI is similar in composition to ER309L with a higher silicon content, which produces weld beads that are exceptionally smooth due to good wetting action. 309LSI is a great choice when cosmetic appearance is important. ER309LSI is used for welding of other 309 type stainless steel where carbon content has to be lower than .03%. The higher silicon content improves arc stability, bead appearance and wetting action.
