I have today experieced my first problem ever on my 250EX and would like your assistance in sorting it out please. It's a 3x400V 250EX.

My settings are these:

- DC - HF - Amps set to 40 - Pulse off - Control set to torch trigger - 2T - Preflow 1 sec - Postflow 5 sec

Apparently it does not matter which Amps I set. The issue I am having is that when I press torch switch to start welding, the amps lower themselves to 008 - and remain there for the whole time I am supposed to be welding - Only a tiny puddle is melted so the 008 Amps are what I'm actually getting. When I release the trigger, postflow starts (amps still show 008) and when postflow stops, Amps return back to whatever I had set them initially. So basically my 250EX is now only able to weld at 8 Amps.

Do you have any idea of what might be happening? Or if maybe you might have encountered this problem before?

Thanks and regards
