Tricky one that, Is there a relay on the circuit board? If so the valve will need to be connected so that it works with the relay, the easiest way would be to connect the valve across the relay coil, but that would depend on what voltage they operate at.
Any chance of a decent photo of both sides the PCB?
It's a varmig 1600, which is meant to be a copy of butters, they now make a 1600c which is Euro torch already but I've messaged them a couple of times with no response, how do I tell if its currently a live torch?
I think it's a Eurotorch conversion, there's no gas valve on the diagram so I'm guessing it's a manual valve in the torch itself.
Feed about an inch of wire through the torch into thin air, release the trigger and the touch the wire on the earth clamp. If it sparks you're permanently live.
I've just been out and checked and it seems like I do have live torch, as if I release the trigger then dap it on the earth it sparks, is it still possible to convert it to euro torch and fit a gas solenoid?
I've just been out and checked again as I wasn't 100% sure but it turns out that I have a non live torch, I've tested it with my multi meter, I think the problem I had is the trigger is very dodgy as the gass runs on quite a bit so I'm assuming this is what caused me to think it was a live torch
If it were mine I'd draw the circuit by reverse-engineering the PCB. If you could remove it (mark the wires) and take photos of both sides I might be able to do something.
Just been out and got some photos of the pcb, I can't hear any clicking but on the pcb the black block looks like a solid state relay but I don't know for sure. Both views of the pcb below are the same the 3 spade terminals on the left are the 6 pins on the left in the second picture
