First thing, thanks for your GREAT web site. It's obvious that you have put in a great deal of time and effort into it.
I am just starting tig welding. I have done about 2 ft of welding (some looks ok but none of it pretty) and many hours watching videos. I have found your videos to be very helpful and a pleasure to watch a master at work.
That said, as a beginner, I feel a "TIG for Dummies" video would be of great help. What I mean by that is as follows.
1. What welder to buy. A discussion of features and the value of each. There seems to be diction on the web about different machines and their features but none seems to describe the value of these features enough so the beginner can make an educated decision on what feature best fit his needs and can grow into.
A. Scratch start, lift start, high frequency start. I tried scratch start then bought a machine with HF and lift start and find it so much easer it is worth every penny I paid extra for it.
B. Option for pedal. I have yet to use one, but can see that adjusting the amperage as the weld heats up would be handy.
C. AC DC. An added expense but if aluminum welding is in their future it would be a better investment to only buy one machine.
You seem to have covered most of the other machine features in your other videos, so links to them should cover machines.
2. Photos and videos of bad welds and what to try to correct them.
None of my weld look like yours. The steel welds look like they are covered in mill scale. I even had little volcano shaped mounds erupt at the ends of my welds (increasing gas flow stopped those). This is the type of problem beginners want answer for.
3. Weld speed. TIG is always described as a slow welding process. Yes, it is slower than other methods, but, as a beginner, it's seems hard to go fast enough. I know that I am way to slow since I start melting through the plate when doing a bead on plate. A discussion on rod size, amperages and inches of weld per minute for a few plate thicknesses would be helpful. It seems that welding speed has to increase as the metal heats, if true, talk about what best to do, Speed up, stop and let it cool? How do you know if you are using to small a rod?
Just a few thoughts.
Thanks again for a great site.
