Lead
I have used both old school lead and the leadfree stuff from Eastwood. To be honest, I use plastic now. For these reasons:
The flux used with lead needs to be completely removed or you will have paint problems.
If you need to back up and reweld something you have to remove the lead, all of it near the weld.
Lead dust can kill you.
That said, if you want to learn it, the lead-free works OK and you can focus your energy on getting things clean instead of focusing on staying alive.
