Should a welder pack in if the rods make physical contact with the workpiece

buy cheap ,buy twice lol
My view.
Happy to be corrected here.
It should cause the machine no issues whatsoever. A constant current process will not deliver any more current than that you set on the machine. So if your arc length is 10mm or in your case stuck to the job it’s gonna put the same current down the rod and the machine isn’t gonna know no different.
Your electrode holder on the other hand might not be too pleased about having a glowing red 2.5 in dead short with the job but the Machine should not care. After all if it’s in dead short or welding it’s doing the same thing as far as the unit is concerned. Your joining the circuit.
It is certainly an current overload as it trips my 16A breaker, so it would appear that the "hot start function" is not dealing with it, and taking out something internal down stream that cant deal with it, you would think there would be front end reset ie as the over current is detected this should trip first before it starts chewing into the PCB,sMy take on this would be a dead short has a lower resistance than an arc so to increase the output to maintain the current might overload the electronics, but as I suggested earlier, they should have some sort of protection built in. Certainly my buzz box hums much louder with a stuck electrode than when actually welding.
