         --Went to Praxxair yesterday to stock up on welding rod. I'd just
snagged a few pounds of rod for mild steel and asked the guy what he
recommended to tig chromoly. His answer was 'you can't do that; you can't
weld chromoly'. Say whaaaaat? So how do people make roll cages? How do
people make tube chassis? I mentioned that in the latest issue of AWS
Journal there was an article about welding chromoly and he said bring it and
then he'd believe it. I'm beginning to think I should switch to a different
supplier: this guy (new owner I think) doesn't look like he's welded
anything in a really long time (too clean, if ya get my drift).

If it was me he was talking to I'd be wondering if he'd seen the quality
of my welds, and meant me specifically.

Do you need to implement control loops in software?
"Applied Control Theory for Embedded Systems" gives you just what it says.

He probably has a copy of the Finch book or a similar text on the
shelves...Just open it up and show him.

Finch recommends using either mild steel or 4130 rod, Welco W1200.

Do not use copper coated rod, use bare rod only.

I hear you. My manager designs and manufactures custom motorcycles and the
like. He is better than most - been in the field and now manager with his
own company.

What I did was go to Praxxair web site and download their manuals. That helps.
I know a little more before I go in since I'm like your manager (:-).
