Not trying to be mean, but that AC only Hobart would have been a much much much much better unit than the one you pictured.
Most of the Chicago Electric welders are not very good to start with and the one you have shown looks to be 115 volt input power. No way is that thing cranking out 130 amps AC or 115 amps DC off a 115 volt input power. If it is the volt/amp curve is so bad that it not suitable for welding.
Now if you have the option of converting the plug to 230 volt input power then it might output the claimed spec's. For $60 though you likely did not get hurt, but you likely limited to 5/64" diameter rods and 1/16" diameter rods with a slight possibility for 3/32 6011. I am guessing your actual output on that unit is 70 to maybe 80 amps max off of 115 volt input power.
If that plug that appears to be a 115 volt plug is a blurry NEMA 230 plug then disregard most of what I said other than most all of the HF welders are not very good.
DC is nice, but it is not the huge welding made easy that everyone makes it out to be.
It says 180amp, so it would have to be 220v. The plug may be the 220v air conditioner type plug. Like you, I can't tell for sure.
