I may have found one issue. During the first welds I was using the filler rods I use with oxy-acetylene. It took some Googling to find out there is a difference between them and the TIG filler rods I purchased today. For those that are wondering, I guess the gas filler rods have more oxygen still in...

I noticed filler rods are labeled "for MIG and TIG" or "for Oxy Acetylene". I didn't notice this while at Air Gas, only noticed it once I got home.

Is there really a difference?

Thank you in advance!

I ran around today at lunch and picked up a gas lens and a 6, 7, and 8 cups. I had to stop and three different places to find the 7 and 8 cups. Question about the gas lens and cups, they do not screw all the way up to the white piece of the torch. Is this an issue? Looking at how they are made it do...

I was using a 3/32 Purple electrode. I don't remember what purple means. My stick out was probably 1/2 inch. Long enough to get into the corner, but no longer. From all of the comments, it should like it may still be too short.

Thank you! I started at 10 cfh, and each try I increased by 5 up to 30 cfh. I have literally welded, ground, then welded this joint a dozen times. For the filet, I also ground it to bright shinny metal to start with. But it looks scaled over when I'm done. Much more so than the flat welds. I have ev...

Can you use the carbide blade in an abrasive chop saw, or is the saw itself special to the cold cut process?

I am using the number 7 cup that came with the welder. With my vast experience :lol: I feel like I'm losing shielding gas because I start to get sparkles. Would a smaller cup size help? It would allow me to get closer both with the shielding gas and the tungsten. At what point is the cup too small? ...

Thank you!

I now have the photos showing up. The forum was cropping out the welds. I tried to crop them at the source, but now they are super-zoomed in.

I've been trying to teach myself to TIG weld via YouTubeU, and so far have been happy with my results. However, I have now ran into a wall and I'm hoping someone and point me towards the path to truth and enlightenment. I am using a Lincoln Electric Square Wave TIG 200. I have some 1/8" angle i...
