I just got a miller suitcase welder . I replaced the liner from the previous owner and put a new tip on. It works great, but i think i need the rubber flux core nozzle. I tried to get it from tractor supply it says works on mm175 and passport as well as hobart 210 PART #770487. I dont think it fits on my stinger from the 12vs . But it looks alot like #226190 flux core nozzle i see on ebay that is the m10 and m15 gun. What part number or setup do i need to make this weld flux core right.TY
