The Vulcans had Dinse connectors for the leads so that's like any newer welder. It'll probably be a matter of time before someone releases aftermarket guns and torches for these so then it's just a matter of running down to the LWS to get new parts. From the looks of it, the Vulcan TIG used WP style parts. I had a Chinese MIG from Northern Tool and when it crapped out (even way past the warranty), I called up tech and they sent me a shipping label to send it off to get fixed. NT has some guy Stateside (it was sent to Wisconsin) to fix these and they were super helpful. They called me when the welder arrived, fixed it in a matter of days, told me what was wrong, and shipped it back. Best part: paid nothing. Not sure how NT is able to do that but I was grateful they did. If HF can somehow replicate that kind of support, I say these Vulcans can steal a huge part of the welding market. You'll still have your die hard Red and Blue guys.
