Scratch start TIG
I have never TIG welded before but have been Stick and MIG welding for many years.
How do you set up a scratch start TIG? Electrode Positive or Negative? Can you weld Aluminum? Can you use AC instead of DC? Why or why not. What can or can't you weld with it? I have a Miller Thunderbolt AC/DC buzz box.
No you will not be able to weld aluminum
AC wont work very well without a high frequency box which will cost more than the welder.
you wont have amperage control but just to give you an idea of what can be done, I welded a 18 ga steel parts washer tank once.
if you want to get into tig welding , since you already have the thunderbolt, all you need is an air cooled torch, a cylinder of argon, a reg/flowmeter.
you will need this stuff anyway if you decide to upgrade.
thanks for the post,
