[TheForge] Welding, soldering and anvil questions

OK, I think it's the click stop amp adjustment, if that's what you
mean when you turn the pointer, and it clicks when you hit the various
amperages. Yeah, I've heard you guys talk about different welders, and
got the impression that they're a good, solid basic machine, although
I get the impression that there's some rivalry between Lincoln and
Miller, rather like the rivalry between Chevy and Ford ;-)

OK, you said:

"It's frustrating at first until you master
> starting the arc without sticking."

I take it, then, that  if I DON'T do a controlled start up like that,
the rod will attach itself to the piece, and do nothing? And by
implication, the goal here is to not quite touch the piece with the
rod? Or am I brushing the rod against the piece?

Then you said:

" Joint preparation and good penetration for that."

How do I determine whether good penetration has been achieved?

Am looking at the Lincoln site now. It's pretty basic, but I'm picking
up some stuff. Will try the Miller site next. I'm finding I know a lot
of what they're teaching, likely picked up by simply being around a
lot of it, and listening to you guys. I think I've got a good basic
understanding of the process- it's the details and the hands on
experience I need, and it's looking like this stuff will give me
enough information to get started.

Thanks ;-)
