CK T3327GTM LaYZr Tungsten Electrode 3/32 x 7, 10 pack

I just did some experimenting with my 3/32 when I first got them to see if there was a noticeable difference to the ceriated and lanthanated that I use for steel and aluminum, respectively. Aluminum was first. I ground a nice sharp point for my inverter and ran a few 4043 beads on 1/4 6061. The standout difference I noticed was after several rods, there was no splitting on the very tip, and very little ball formation on the point even running at 30% EP. No spitting either, though it was a short session and I dont get much from the La electrodes either. During the session, being an old shaky guy, I duffed the electrode a few times, but it shook it off like a champ and I kept on going. Then a fly flew into my arc and exploded carbon all over. same result, just kept going. End of session a small sphere had formed but little else and didnt have to re-sharpen once. Then on to steel. I put a nice slender point on the electrode and ran some beads on different thicknesses from .040 to 1/2 steel and some stainless. The several rods later, the point looked the same as when I started. It stayed clean and sharp. Further, to test the low amperage behavior, I welded some rod remnants together. My machine has a hard start, so it takes bit of control to stick an .040 rod together. All went well and Im really considering putting my La and Ce on the shelf and just working with these. Really happy with them and will be getting some 1/16

These start nice and retain a point well. I use them for both aluminum and mild steel with great results. Makes me feel like Im back in the weld shop 30 years ago.

It’s a good all purpose tungsten. I use it on an inverter tig welder. For dc and ac welding. Good arc starts even on lower amps. And it holds a good point on aluminium/aluminum ac welding. Better then the 2% lan.

If you want to avoid radiation, and use something that keeps its point, look no further.

This is pretty much my go to now on stainless or aluminum, great arc stability.

Welds everything with no problems.
