Sounds to me like you are cramming for a final. If so, you should find the answers on your own. We wouldn't be doing you any favors by giving you the answers.

  1. preheat
  2. Makes it hard but brittle
  3. The electrode core / filler rod
  4. Molten flux.
  5. Straight I think
  6. The length the wire "sticks out" past the tip
  7. Carburizing flame
  8. Must be used DC Straight only.
  9. Electrode not big enough, current too low as a result. Or no edge prep, ie groove or bevel.
  10. filler rod dipped in molten pool.

When used in the context of "I have know idea", I guess one could derive a philosophical bent. As in, "We don't need no stinking English or spelling classes!" Which seems to be the mantra of the new generation.

And then they wonder why they have trouble securing rewarding positions in the workplace.

Guess philosophy IS the way one looks at things.

Point well taken.
