Simple, inexpensive transformer welding machine, usually AC-only or AC/DC, sold for farm, hobby and light repair work and named for the hum it makes. It has little more than an amperage selector and runs rods like 6011 and 7014 that behave well on AC. Many welders learned on one, and the name gets used loosely for any basic stick machine.
Heard on the job
Grandpa's buzz box runs 6011 fine on the fence posts, just don't ask it for 7018 overhead.
