[edit] Image Inclusion

I've never seen Plasma weldong before - Plasma cutting, but not welding. I think an image would spruce this up quite a bit :-)

[edit] Plasma gas?

Isn't that like saying a "solid liquid?" AFAIK, plasma is considered a phase of matter distinct from gas, but IANA physicist... Anyone better-educated care to throw in their 2¢? El Mariachi 09:48, 18 May 2006 (UTC)

You're right, but I'm not sure off the top of my head if "plasma" here is used in the scientific sense. It might just be the name. I'll look into it. --Spangineer^[es] (háblame) 12:14, 18 May 2006 (UTC)

I've found a lot of information on how plasma is defined (basically an ionized gas), but can't seem to find what the gas is made from, for plasma welding/cutting. For neon lights and plasma TVs, it appears to be neon. What is used for plasma welding/cutting? Perhaps this could be put on the Page. Or did I miss it?

[edit] Orifice Diameter

The article refers to

Micro-plasma (< 15 A) 
Melt-in mode (15–400 A) 
Keyhole mode (>100 A) 

Is the "A" here meant to be the Angstrom symbol, " Å "? If so, the character code is Å. I'd make the changes myself, but for all I know the "A" is some arcane term from the welding field and should stay just as it is.

A stands for Ampere, the current intensity unit.Whistopathe 00:32, 14 January 2007 (UTC)

Thanks. I've updated the page, and can now stop watching it.
