Microweld help

[Ajkirby]

Hi
I have a microweld A plus that's about 40 years old. It's started trying to burn back along the tips, even on a 22. Also the leak light is pulsing on and off when the torch isn't on. Does anyone have any advice, would a service sort out the problems? I have tried changing the MEK, as that was my first thought when it was burning back. Any help would be gratefully appreciated, I use it for my business so could without it being out of action.

Maybe worth a call ? I've used a guy in Birmingham that repairs them aswell but I cant find his details but he was good and turned it round fast.
