Review on SPARC TIG Tungsten Welding Electrodes: Set of 10 Purple Electrodes, 3/32, 7 Inches - ANSI/AWS Compliant, Ground Annealed - Welding Accessories with Low Burn-Off Rate by Bill Howard

Revainrating 5 out of 5

Still learning TIG Welding

was corrupt So I'm not a great authority, but I appreciate the choice these packages offer. The description says they are a good alternative to thoriated types, which I understand contain a radioactive component. I'm still learning where these different types can be useful, but I'm glad I can keep a few options handy.

Pros
  • High Performance Tungsten Electrodes... SPARC TIG Tungsten Electrodes are composed of E3 mixed oxides (purple) for low burn-off and predictable arcing at high currents; Excellent general purpose electrode for welding carbon steel and stainless steel.
