I really was wanting to believe Airgas Hawaii was passing some bad gas, but I got a call from Jeff Johnson at Miller in responce to my inquiry on their website some time ago. He called me and went through it for me and pinpointed it being the...

I am a life-long artist - I guess I can say that since I am 70, day after this coming Christmas. I learned to more or less TIG in 1991 on an old Airco 300Amp for my sculptu...
