At Arc-Zone.com we get a lot of requests for tungsten electrodes made in the U.S.A. And until recently, we weren’t able to offer that.

Sylvania (yes, the lightbulb people) are at present the only US source for tungsten electrodes. Nearly every tungsten electrode comes from China (75%) or Austria, Bolivia, Portugal, and Russia.

If you’re interested in learning more about tungsten production, there’s a great new website that offers some of the most comprehensive information about tungsten and tungsten electrodes for welding that I’ve seen in a while. (Yes, I may be a little biased, but there really is some good information about tungsten there.)

Now, Arc-Zone.com offers Sylvania Tungsten Electrodes, made in the US, and ready for immediate delivery:

• PURETUNG® / Pure Tungsten (Color Code Green)
• 1% Thoriated (Yellow) Tungsten Electrodes
  
• 2% Thoriated (Red) Tungsten Electrodes
  
• 1.5% Lanthanated (Gray) Tungsten Electrodes
  
• 2% Ceriated (Orange) Tungsten Electrodes and
• ZIRTUNG® / Zirconiated (Brown) Tungsten Electrodes
  

Arc-Zone will be stocking the standard 7″ length in diameters, 0.040″ to 1/8″ though other diameters are available. Contact sales –at– arc-zone.com for details.

Another great tip from Weldcraft®

For excellent arc starts on low-amperage AC or DC applications, use 2% ceriated tungsten (color code: orange) especially on carbon and stainless steels.

For consistent performance on all metals, and for all machines, Arc-Zone.com recommends our new ArcTime™ Hybrid All Purpose Tungsten:

Professional yacht tower fabricators, manufacturers of aerospace parts, and mountain bike builders have all selected ArcTime™ because of its excellent ignition properties, low burn off rate and longevity. As an added bonus, this hybrid tungsten electrode works well with all power sources and all metals from mild steel to titanium.

“You’ll notice a difference just by striking the first arc– no finer electrode exists anywhere,” says Jim Watson, aka Joe Welder, president of Arc-Zone.com, Inc.

Another great tip from Weldcraft®

Maintaining good electrical contact between your tungsten and collet helps improve current transfer and weld quality. Keep your TIG torch components tightened and check regularly for worn parts.

At Arc-Zone.com we offer a free, downloadable PDF on the correct way to grind tungsten in our Welding Library, but here’s some quick tips from the Weldcraft® catalog to get you started:

• Grind your tungsten electrode Longitudinally, not radially
• Prepare a tip flat
• Use a dedicated wheel for grinding tungsten

We also recommend a dedicated tungsten grinder for TIG / GTAW welding and Plasma Arc Welding (PAW) applications.  Arc-Zone carries a full line from the handy, inexpensive Sharpie(TM) hand-held tungsten sharpening tool to the more rugged, precise DGP with a fully integrated vacuum system.

When cleaning contaminated tungsten, do NOT break off the end of the tungsten.

Breaking tungsten can cause splinter fractures, resulting in erratic arc. Use a cutoff wheel or the edge of a grinding wheel.

At Arc-Zone we would add the recommendation that you use a dedicated diamond wheel for grinding to avoid contaminating your tungsten.
