Hi all,
I was given a Maypole Turbo Mig 140 about 10 years ago, and I've been able to do a load of fabrication work with it, until the gas line in the torch started to leak.
Along with leaks from the gas pipe in the torch lead, it started leaking from the switch assembly at the torch end, the welding wire has started getting stuck in the liner etc.
I decided that it was time for a euro-torch upgrade.
I've managed to integrate the euro-connector pretty well, but as many others here - I simply cannot fathom where to install the wiring for a gas solenoid.
I've probed various areas with a multimeter, but still can't seem to figure out where I would attach the wires.
I know that typical choices are either a 12v, 24v, or 240v solenoid.
The PCB is a 114057.
Reading other posts on the forum, I've seen that some have a "contactor", whilst others have a triac.
I've taken photos of the pcb, and hope that someone might be able to suggest the best place to source a signal to switch the solenoid on/off when the button is pressed on the euro torch.
In addition to the regular photos, I've also edited one, flipping the track-side horizontally, and then over-laid most of the components on it, to show the tracks and the components.
Any guidance is really appreciated.
