I've had an ESAB 215ic for a few years now. I decided I want to learn how to TIG so I leased a tank of Argon and am ready to go. I have three different sizes of tungsten rod but none of them are ground to a point. What ange is a good starting point and can I use my belt sander to do this? I don't have any filler metal. What would be a good filler rod to buy for low carbon hot rolled? I just want to figure it out on some cheap material I have around the garage.
