arc temperature?

[Sammy da bull]

Got into an argument today.... I read in a few places where the actual arc of a mig welder was estimated to be between 6000 and 8000 degrees F. He said I was full of it. I told him i would post a thread here hoping to get some good documentation proving me right.... anybody got a link for me? Thanx.

Heres a site that states the temperature of a MIG arc to be in the 6000-8000 degrees C range. Thats more like 10 000- 14 000? dergees F.

heres a question I have, How do you make the little degrees sign on the keyboard? Instead of writing out "DEGREES"?

* is the common Degree symbol on Forums.


And do the math. Electric arc+molten metal=WELL over 3K*

Degree sign is easy......Press and hold the alt button....and enter 248 on the number pad



10,000° is where I was thinking, but didn't have the backup data.

10,000° Hey !

° Thanks!!!

The arc temp is much, much higher than the temp of the molten metal. It is also amazingly difficult to determine, as little material in the vacinity of the arc will be un-ionized, and the arclight will swamp the black body light used for temperature measurement. The estimates are typically 6000*C or higher, based in part on a bunch of awkward calculation of energy input, electrical resistance heating, heat transfer, etc., generally involving enough estimates to give a pretty broad range.

...and for a Plasma Cutter, I believe that doubles or triples!

° ² ³ ¢ ñ and all that stuff in in your character map. You can either use the "Alt" key + the numbers, or select and paste the objects. You'll find it in start/accessories/system tools. I put a shortcut to it on my desktop. There may be more than one map available to you - check it out!

Plasma arc - 24,000°C

6,000-8,000 °C for the GTAW, GMAW, FCAW and SAW processes

Proving Hotfoot's input, once again, to be absolutely infallible!

8,000° c

Really Neat

Anyone have a simple easy to follow map of how to create these symbols with the common PC keyboard?

That should help you out jerry
