pp50 problems

[fitter]

Hello, I was using my pp50 and everything was fine. All of a sudden, all I get is a faint spark. Changed the tip and all hardware, cleaned area where ground is hooked up. Any thoughts? What should the inside of torch look like when taken apart? Thanks

Sorry you are having an issue. But posting a picture of the inside might be better. I am not really sure what you are asking with the question. Ideally, it should look like new, if you are using dryers mounted inline. The plunger/piston part should move in and out smoothly, and fairly quickly. Have you trie to scratch start it?
