My current contact tip adapter will not accept the fine thread miller contact tips. I've been using the coarse thread Lincoln tips since I started using it. The threads look worn out on the tip side so I kinda figured that was why. I bought a replacement tip adapter and the tips fit as they should but won't thread onto the MIG gun. The threads on the gun look fine and the old adapter threads on and off easily. Also, the old style has an O-ring and the new doesn't but they share the same part number. What's the deal?
