Welding Tips and Tricks

Well I have cooked the torch head on my tig welder. I have the Alpha tig 200X and have run it too hot for too long and the rubber around the body has deteriorated. I have found several on ebay that look the same other than the gas vavle.

Are all the WP-17f torches the same? In other words will it thread onto my hose?

That's a standard 17 I use then a lot at work. Get a flex head. There all about the same from all the manufacturers.
