At Work, I mend PE Pie welding equipment for the Pipeline industry, these things are capable of welding 50-60A continuous for 1/4hr or more from 110V or 240V supplies (the fusion time is precise).. and we set them up at up to 100A as above during Calibration.. so they're full of huge components, Triacs, Thyristor packs and big fat wires as you might expect..

But since I started again on Monday, nearly every unit I chucked on the bench has had this resistor faulty giving a resistance measurement error (different types, different models, different customers) yet in the last 3 years since I returned to the fold, I might have replaced 3 maybe 4..

Forum 143

Yes there is a component there..

Not only that, but some of them.. after definitely repairing that fault, still had another fault giving exactly the same error.. (One I had to put to one side for more time..) my head started to hurt this afternoon..

Why do things choose to die like lemmings all in one go??

The things I have seen are plastic gas pipes. They appear to have a wire coil in each connector that the workers plug into a generator for a set time in order to seal them.
I can't see the photos you have posted for some reason.
I will check again to make sure it is not me though.

Is the dead one the vertical one in the middle (looks like R46 or R16)? Wouldn't take a lot to fry it- looks like an 0805 or smaller.

The board looks like something died under the bottom right mounting hole too, or is that just mucky dust?

Isn't PIE welding just a standard northern technique for attaching the crusts onto steak pies?

Yep that's the dead one, in most cases there are no outwards signs of it's demise.. and just mucky dust, the pillars were loose and have rubbed the holes to dust.

Oddly enough we have our Russian people here today and the engineer just came and asked me .......

About resistance Errors!! (on a different unit again) :bbd

Having had just a few of these in the previous years, why has it suddenly become enemy No1? :aai
