To me I think that machine would be a waste, it doesn't have high freq which I think would be almost a necessity as well as huge convenience on sheet metal. Which is all this machine could do with only 95 amps@110v. In addition it doesn't look like there is any provision for amperage control(foot pedal or slider), which is def a necessity for doing sheet metal. You need to be able to get off the heat or else you'll be burning through stuff left and right, not to mention melt through(looks like lava) when doing stainless. I'm definitely biased on machine choice cause at work all I use is millers. That rhino machine is basically a stick welder retrofitted with a gas fitting so it can tig, not a machine dedicated to tigging. Also 20% duty cycle is not very good, in reality thats only 2 minutes welding...8 minutes resting @95 amps in a 10 minute span which is how duty cycle is derived for welders. Sorry for the rant but don't want you to waste money on a machine that won't do what you want it to. For reference I am a welder for the navy repairing nuclear fast attack subs.
