Question about Welding Tools
The above reply is very good. If the contactor is buzzing, it will need to be blown out with high pressure air. When I was a welding repair shop manager, we washed every machine out with a pressure washer and then we blew the machine out with high pressure air. When dealing with high electronic machine, you have to avoid getting the electronics wet and high pressure air can damage circuits and wiring. Contractors are easily taken apart and cleaned. WARNING: Any work done on the inside of the machine should only be done with the machine unplugged or locked out. Good luck.

If water gets into electrical equipment the big danger comes from current flowing through the water / moisture where it shouldn't and damaging something.
The equipment needs to be dismantled and completely cleaned and then dried before applying power to it. This usually involves leaving it in a warm dry atmosphere for days, best with a dehumidifier and/or fan going.
Once current has done damage it usually means components need to be repaired or replaced, so be patient and wait until all moisture has been totally removed before applying power.
It may be possible to recover the welder even after it has been powered up by dismantling and thoroughly cleaning and drying if no permanent damage was done. All traces of silt and moisture must be removed from every electrical part before voltage is applied.
