All that's left is to install the nose cone. This is a very simple job and took less than 10 minutes from start to finish. I am not sure why anyone would ship these off to be repaired, but when I went to my local welding shop to ask about the repair kit, that is what they offered me instead of the kit. They send regulators off once a month to be refurbished. They also told me that I should not work on this myself unless I am a trained technician.
