So as looking at the back of the plug as per Hugh’s photo effectively you short bottom left (red) and right (black) for starting the arc and up selection and short bottom left (red) and middle right (green) for down selection.
Hold the toggle switch up while turning it on and you’ll be into a menu probably starting with pre gas.
Short out the pins as I’ve shown you and you will see it works and the value goes up and down
You don’t need a torch to test it. A short piece of wire between those pins only will confirm what you need to do.
I only used the 2 bottom pins on my torch switch to start the arc.
I fit a momentary switch to the machine by tapping into the back of the plug for the other functions. Again though I only used the 3 pins as shown
Hy again i put the new torch and thanks to brave people on this forum everithing works great ,this transtig 2000 is a great machine its my first tig welder i want to ask what is the switch on the front pannel (ie) it works from 0-100% but i don't know what is it.thanks
Hi Andrei, sorry I didn't get back to you - thanks to Richard for getting you up and running. I had a lot on at the weekend and didn't get a chance to go through my notes.
