Need Any Welding advice?

They created the word "weldor" to differentiate between the machine and the person. Like... The weldor is happy with his welder.

And vice versa obviously, but with a bit of a twist.:D
So if someone said "go get the welder" the person wouldn't come back carrying the guy.:D
That's cool though, as I had no idea there were different spellings solely to differentiate between the person and the tool.
Interesting.
Thanks again.
