Up
For sale is an ESAB/AIRCO Heliweld HFAS-1 High Frequency Arc Stabilizer. Military surplus. Powers up and produces a humming sound. Untested beyond that. Front controls look quite clean and sharp. The superficial scratches on the body are not rusty. I suspect that it has seen very little use.
You can use it to tig weld with a AC/DC welder
.What you see is what you get.
