Question about Lincoln Electric K1297 AC/DC 225/125 Stick Welder
Unit went through a flood. Worked for a few hours after cleanup, but with a buzz. Now the unit has no output and a really loud buzz, and one contact on the voltage selector switch is fried.
You have a shorted diode in your rectifier. It's basically a direct current short. The switch was damaged (more than likely the contacts soldered together) when it was turned. The diode is an easy fix if you're electrically inclined and can determine which ones are shorted and/or open. The switch is a pain to replace, though. The diodes were $25-$30 20 years ago, the polarity switch was $50-$60, and I charged $75/hr labor. That repair would have cost you $250-300 if I did it 20 years ago. Probably much more now.
