Re: tungsten sharpening - help

Steve: Maybe I should not have called it "balled up", Maybe I should have said, the tungsten seems to attract slag or impurities about 1/4 to 3/8 inch from the tip (the portion inside the ceramic cup). from this point to the end of the tip the tungsten looks dirty, almost black. I end up g...

Re: tungsten sharpening - help

I did more practicing today on sheet metal, I found the problem I was having with the trungsten being dirty and partly balling up was because the metal was not clean enough, put some acetone to it andsince I was doing a couple inches of weld at a time, I wire brushed the area before restarting which...

Re: tungsten sharpening - help

Steve: Its an Everlast PowerPro 205, which is connected properly with DCEN, AC/DC switch set to DC. I doubt very much that it is the machine, there is no HUMM as in the AC frequency, I'm sure its how I have been grinding the tungsten or possibly torch angle. Also the fact that I'm a noob with TIG. T...

Re: tungsten sharpening - help

Steve:
I'm using it on thin mild steel, DCEN, TIG. pure Argon gas, flowmeter set at about 8 LPM at the flowmeter. often I end up with a big ball on the tungsten about 1/8 to 3/16 up from the tungsten tip which I cant explain
Thanks

tungsten sharpening - help

I have watched Jody's videos and noticed how fine an arc he can create in every scene. I have tried grinding my 2% lanthaneted tungstens on a regular 6 inch oxide wheel, then fine finishing it on a diamond wheel. I've read a good article on the oxides in the tungsten and the proper procedure in grin...
