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

I’m using the 3/16” LaZYr (chartreuse green) tungsten on 1/8” aluminum with and without pulse and in my opinion it performs better than the purple (2% Lanthated) with slightly dirty aluminum. That’s a plus when doing aluminum repairs and you can’t get the aluminum as clean as you would like. Amazon prices are far better than those from my local welding suppliers.

Great tungsten. Everything CK makes is top notch but this Layzr takes the cake. I ordered some 1/16th also to go with this 3/32. Using a Furick Fupa 12 cup and gas lens makes it the perfect combo for stainless and other DC applications.

Absolute favorite

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

Despite the fact that they start well at low amperages and stay sharp, which ultimately makes them a fantastic replacement for Ceriated tungsten...the arc however is not crisp and direct at low amperages. It wanders. This is bad and its just as problematic as ceriated tungsten which wanders as well. I have to do micro welding in which I place a weld between two items but this tungsten will arc jump onto the other materials or surfaces. It ruins my parts and makes me very angry. Lanthanated and thoriated tungsten do not do this. Layzr tungsten is not better than 2% lanthanated. It does stay very sharp and its very visible so its a quality product per se...but I will not buy these tungsten again. I bought these for $20 a pack, and about 2-3 months later, they are now up to $30. They are not worth it.

Holds up really well, very versatile, so far it’s gonna be my go to tungston.
