Is there any way to increase the duty cycle?


yup, buy another welder! serious though, duty cycle is one of the key features you need to examine when spec'ing out welders. now you understand why that harbor freight deal only ran you $200.

a welder is one of those things you need to dish out the extra cash up front, you don't want to be buying one twice. and stick to the name brands (Miller, Hobart, Lincoln, etc), anything else you'll be disappointed.
