They are NOT non radioactive

I have a Radex One geiger counter/dosimeter which I put on a new pack of 10 0.040 x 7" electrodes. It showed 0.28 µS/h, with a background value of 0.10 µS/h. 1/16 electrodes and various brands from a local supplier of welding consumables. Dividing the reading by the volume of the electrodes gives me very different numbers for 2% thorium (no, I didn't mix up the data - I measured too badly) at 0.08 µS/hr per cm3 (3/32 inch) and 0.35 µS/hr per cm3 (1/16 inch). bad, but definitely radioactive.

Pros
  • Easy to use
Cons
  • Everything is fine

Tungsten panacea (if such a thing can exist)

If there was ever a solution to the argument over which tungsten electrodes to use for steel and aluminium, purple would be the solution. If you're new to welding, buy a pack of diplomas and you can't go wrong. At least you can't blame Wolfram "if" you do!

Pros
  • AWS classification: EWG (purple). Conforms to ANSI/AWS A5.12M/A5.12:2009 ISO 6848:2004 MOD. The earth is scorched.
Cons
  • unreliable

These are great things!

I usually weld 22ga sheet metal for car bodies and this is fortunate. The purple tungsten is great and the quality of the arc is noticeable. I am very impressed with the performance and durability of tungsten. The only advice is to get a Dremel + diamond wheel to sand them down. They're pretty flexible if you're not careful.

Pros
  • USA Welding Gear and Equipment Suppliers. Strong technical support with experienced customer service to solve any buyer's questions.
Cons
  • Miscellaneous Miscellaneous

Dividing the readings by the volume of the electrodes I got very different numbers for 2% thorium (no, I didn't mix up the data - I measured to be sure) at 0.08 µS/h per cm3 (3/32 inch) and 0 .35 µS/h/cm3 (1/16"). These .040 Tri-Mix electrodes have a reading of 0.12 µS/h/cm3. Not bad, but definitely radioactive.

Pros
  • Mixed trioxides of lanthanum, zirconium and yttrium with a total rare earth content of approximately 1.5% - 1.8%; Tungsten remains. Non-radioactive tungsten electrodes; excellent replacement for thoriated tungsten electrodes. Wide current range and low burn-in rate. Easy arc start and good stability.
Cons
  • I don't remember but there was something
