I have a Multimatic 200, and am busy teaching myself how to weld, as I have time.
It's time for me to try TIG, and I have a couple of questions.
1. Using lift start on the Multimatic 200, I do not have a pedal, so I assume that I touch the tungsten to the work, and then when I lift the arc ignites. Is that correct?
2. Does the 200 turn on the gas prior to igniting the arc?
3. Once the arc is extinguished, does the 200 turn off the gas?
4. Any way to control the pre/post flow?
5. When extinguishing the arc, I have seen on videos where a "snap" or a rapid arc of the torch is used to extinguish the arc. Is that the normal technique?
6. Why is the arc not extinguished by pulling the torch away, so that the gas continues to flood the surface and electrode?
7. On the 200, is it possible to select between lift start and scratch start?
Oh, I got a smaller torch, because most of the things I expect to TIG are small, and I figured it would be more maneuverable.
Thanks in advance for your considered comments.
