tig welding steel problem, the arc isn't getting hot enough
Posted: Wed May 19, 2010 10:21 pm
I am trying to tig weld some 1/8 inch steel tube. I have a miller 180 sd which should easily be able to do the job. I'm using 2% thoriated tungsten that is 3/32 , I have the selector lever set to DCEN and my amps are at 130. The tungsten isn't balled at the end it is at a point and it is ground in the correct direction. The steel is clean and I have no contamination on the tungsten. However, when I hit the remote peddle only a very small and weak arc comes out. It can't even puddle the steel. I can tig weld aluminum just fine so I have no idea what is happening here.
Any ideas?
thanks,
