[TowerTalk] What Welder Makes Good Exothermic Bonds?

[doc]

I would like to start looking for a welder that may be used to make
exothermic-quality welds.

What features should I look for in a an affordable occasional
use device, please? (i.e. not a commercial duty-cycle)

I will not only be using it for the house and tower-related
grounding projects I will also be needing to do some repairs
to my two trailers and my van and may then pass it on to a
friend who is starting up a farm.

Thanks! & 73, doc kd4e
