With wires well up off the ground, I bet it's fine. You know how companies are where liability is concerned. I was going to go with predator style electric fence (wires close to ground and spaced closely) around my property, but due to two sides being in wooded areas with leaves, and another...
Weed burners are continuous current. It appears they can be a fire hazard given the right circumstances. Premier1 advises against them, as a fire was caused by combining their netting with a continuous current charger. I would probably avoid them and go with a low impedance charger.
I love...
The point is to run a low impedance charger that boosts voltage when the fence load increases due to weeds, not burn them.
This is taken from Zareba:
To combat excessive weeds, use low impedance energizers, which are capable of increasing their energy output as fence load increases. As weeds...
