For those reading this who may be contemplating the acquisition of a tig,
inverter units have significantly lower power demands from the wall. My 200A
HTP Invertig requires only 24A or so for full power, so it easily runs on a
dryer outlet on an extension. I can take it almost anywhere. It's also light
enough to move easily by myself.
I expect other brands have similar traits.
