mikerj:
The gas valve and motor feed are powered from a separate 24v transformer, so either the transformer is wired incorrectly (i.e. powered from 240v but transformer primary configured for 110v) or the gas valve solenoid has shorted turns and if drawing way too much current.

Possibly useful thread on mig-welding.co.uk regarding common failures.

Transistors looking good is not enough.

No, i'm not sure. The valve heats up quite quick, so i have 20-30 sec to measure. - Thats why I'm asking here.. And thanks for your aggressive pointing fingers..

Thanks to all others that replied :) I won't do any further today.

That's not pointing fingers, that's basic troubleshooting. Without even having the voltage at the solenoid measured, what do you expect us to tell you? We can make a guess at best, as mikerj said: Either wrong voltage or shorted coil.

20seconds are plenty enough to measure voltage. Even 5 seconds are enough for a multimeter value to stabilize for a readout.
