Had a cheap harbor freight style air blow gun develop a crack after years of abuse, so I welded it up.  At first I thought it was still leaking, but after further thought and inspection it was leaking from the fitting, which it had done for quite sometime.  I later added some teflon tape and got it sealed up.  The blow gun was some type of cast aluminum and I used 4043 aluminum tig filler rod.  This was a quick, easy and fun repair
