Good tips. I was just playing around with some stainless, then mild steel. I tried the welder out but its not at my house yet. What would you suggest practicing on first? I read start with thicker stuff then work your way thinner as you get more comfortable with the pedal and stuff. I also need to learn how to hold/feed my filler rod. I did about a 4 inch bead and my fingers were too close to the puddle to keep feeding. I saw a guy push it through his hand with one finger... kinda difficult.
