Jody, here.

I have done a bunch of tests on electrodes of all types.

(E3, ceriated, thoriated, and pretty much all the rest) 

I believe 2% lanthanated is the best all around type of electrode for AC and DC as well as for inverters as well as transformer machines.

So to keep things simple, 2% lanth is all I use now.

But I still use different sizes.

I keep a 3/32" tungsten in my torch most of the time because it usually does the trick.

I use 1/16" for really thin stuff and anything under about 60 amps

I use 1/8" for aluminum when I have to go over about 200 amps.

So here's a bundle that will allow you to get all 3 tungsten sizes I offer right now, from CK Worldwide (all come in packs of 10):

• 1/16"
• 3/32"
• 1/8"

All 30 electrodes for $106.99.

That's $15 off. I think it's a pretty great deal.

Save some money and grab this bundle!
