As you know, Arc-Zone.com(tm) carries the welding industry’s most complete line up of tungsten electrode sharpeners on the market, from inexpensive hand-held tungsten grinders like the Sharpie(tm) to more robust, precision grinders like the DGP. We also carry a mid-range of grinders like the Pirahna II. You’ve probably seen this grinder other places. In fact, we regularly see this grinder advertised in all the trade publications, and recently noticed a little inconsistency.
In the April 2007 edition of the American Welding Society Product Review section of the magazine, the Piranha II ad says:
“Perfect for nearly all welding applications this portable unit (under 7 lbs) is comapct and durable with no vibration. Grinds .040″ (1.0mm) through 1/8″ (3.2mm) tungsten at any angle from 15 to 45 degrees.”
Now we have nothing against the Piranha II. It’s a good, solid machine. We sell a lot of them. However, the Piranha II does not prepare 1/8″ (3.2mm) tungsten. It used to be manufactured to accommodate the 1/8″ diameter electrode, until it was discovered that the motor was not robust enough to handle that larger diameter– at least not for anything more than occasional use.
