For sale is a set of Forsstrom plastic welding electrodes for welding plastics. Used by owners of Forsstrom machines to weld plastic for making truck covers, boat covers, circus tents, and other serious stuff.
The electrodes appear to be completely unused and one of them still has pink protective plastic over little pieces. (others do not need to be protected like this).
What this is, as I learned, is a Forsstrom kit for plastic welding. See forsstrom.com. They sell equipment for making pools, truck covers, circus tents, etc. The process is called "high frequency plastic welding". Those bars are similar to what you see here: http://www.forsstrom.com/hf/pages/products_accessories.asp?lang=uk used on machines such as this: http://www.forsstrom.com/hf/gfx/photos/products_dr.jpg http://www.forsstrom.com/hf/pages/products_products_dr.asp?lang=uk these are the bars that are inserted into holders that hang over work tables. They are somewhat interchangeable, I think, and slide into the rails of those gantries.
What you see is strictly what you get! I have no idea what they fit, but showed EXCELLENT, very high resolution pictures with yardsticks included where it was possible. You can see how big they are etc. Come in original case.
