UD Smoker?

Well unconventional your luck the classes are on Tuesday and Thursday night from 6:00 to 9:00 each night. Check out Palomar's web site and registration will start sometime in late July or early August. Classes fill up fast, so try to get in early or at least get on the wait list and if all else fails you can crash the class. Secondly if you oxy-fuel weld and braze you will be a natural at GTAW. You already have the hand and eye coordination and I'm sure you can read the puddle. You'll just have to learn to control the heat input with your foot instead of moving the torch in and out to control heat as in oxy-fuel welding.
Hope to see you there and keep me if you have to crash the class I'll make sure you get in LOL... 12 years there as an instructor and I have a few tricks up my sleeve to get people in class.
