Put the torch that works into the dinse and connect the gas. But leave the 5 pin amphonel connected from the torch that your having trouble with and see if that triggers the machine to weld. This will rule out/in any wiring issues with the other torch
Its a binzel torch i realise now the power has to run along the red line, i will have to get another dinse adaptor to run the water from the cooler, and make something so i can run my gas along black line without cutting the end off, wont be the end of the world if i have too, when sorted ill put a picture up, thankyou folks
