Around 12 years ago I attended a father's day expo at the local Mitre 10 and there was a Ryobi rep selling various Ryobi welders including one that according to the rep was the "most powerful" arc welder (160A) available in Australia that could be run using a 10 amp plug.
However yesterday while browsing in Bunnings I noticed the welder (170A) illustrated below and it also uses a 10 amp plug.
Is there a limit (amperage on the welder) using 10 amps? Why do some require 15 amps then?
Cheers
Graeme.
