No. the problem is that the wire feed is running al the time. Thats why it was in for repair but the coud not figure it out and said it was the fzj101 but they coud not get it anywher...
it did weld before it was in for repair but now it doesnt.

I also noticed something. when I touch the right til111 on pin 6 base it triggers the gas valve and the contactor. and yes these have been replaced by the ones who previously had a look at the board, coud they have been installed wrong? the soldering work doesn't look to good either.

Looks like Stevie wonder had a go at fixing your welder mate...

if there resisters not diodes should not make a differance ?
but i would defo sort out that soldering thats a mess
and looking at that soldering i dont think they had half a clue on repairs if thats the state of the basic soldering skills they have

Don't know his name, but not a real wonder I looking at the soldering work he has tried to do.
They are optocouplers, thinking they where installed in the wrong way

I would say to clean up the tracks and use wire to make decent connections, if they are diodes then they will not work properly however they look like resistors and it won’t matter which way they’re installed !

You could try de-soldering them and install the right way...
If they are installed wrong they can not work like they should or at least that's what I can make of of what I have read on how they work they more or les work like a relay, if you connect the signal wires wrong on there it won't work eiter

sorry just seen ^^ sorry missunderstood just thought you where looking at the resisters
but still sort the soldering out would be first on my list
what make you think they put them in wrong i cant see markings on the board ? unless you have a circuit diagram (and at this stage it sounds like thats what you might be needing soon

Wel what makes me think that they are installed wrong is beqause they heve been replaced and it used to weld and now in doesn't do that either. Only wire feed that keeps running. Then I was looking at how they work and noticed that the need a smal voltage as a trigger but are used as a sort of relay and for a higher voltage. Then I looked at the pcb and saw that it seems like pin 1 and 2 anode and cathode are in the wider tracks on the board that does not make sense to me, or does it?
Hope this makes it a bit easier to inderstand
If you look at this picture you can see that left one seems to be installed in the wrong way
Pin 2 is connected to the wider track on the board so that can not be ok lit that beqause it is the cathode and I woud think that it schoud be collector that is connected to that spot.
Pin 3 and 6 are not used so they shoud be free of solder.
I am going to take them of and clean up the mess they made.
Let me know what you think of what I think of it being installed wrong

Cleaned up the mess as good as I coud had to use some pieces of wire to make new tracks they where burnt of the board. and put the til111 on the pcb in the way I think they shoud be on there makes much more sense to me.
On the second picture you can see how I installed the til111 now.

The important question, does it chuch ?
Wil see what it does now going to the shop now and connect it
If I had a circuit diagram things woud be much easier I gues but I can't find any info about this brand of welders it seems to be German made for a Dutch company that of course does not exist any longer.

if you swap them round you might do more damage as you could send power down where its not wanted
and whos to say they actualy put in the right components when swaping them out
need to find a diagram or send it to someone that got know how and with the circuit diagram or im afraid your ******* in the wind

Ok I wil wait then with connecting it.
I don't know where I am going to find a diagram of it. haven't found annorher mig like this one, or from te same brand and I have been looking around for a while now before I found this forum.
