When are you going to step up to Google Chrome as your default browser? All the cool kids are doing it.....
What I did learn was this: there were some days when I couldn't weld a damn thing at all and just had to walk away from it. Other days, I was perfect and could do no wrong. When things are going bad, ask the instructor about techniques: there are four things that you can change (angle of tip, distance from the work, voltage, wire current feed speed) that give you a wide range of working conditions. If you screw one up and don't compensate, then nothing will work!
