This is a Hobart CyberTig (Cyber Tig) 200 DC-S welder that I bought on eBay for $9.99. Ebay item number 5615601498. This is a programmable welder capable of TIG and arc welding. It has an automatic gas valve for argon and water valves for torch cooling. Preflow time and the rest can be programmed, so this welder lends itself to automatic welding operation.
This is a three phase device, which I am running from a homemade phase converter that I recently built.
Model CD200DC-S, Spec 6426-1, S/N 81WS25470. Here's the Hobart CyberTig 150 200 Manual and Hobart Cyber Tig 800 Programmer Manual, in PDF.
Its seller is highly recommended.
