thanks for the info Dave !!!! Makes sense..

Yup that is it. how can it be a 300 with a 200 amp secondary. Got to have it high range about 75 on dial to burn a 1/8 7018. And it is set for 220v input

Got a airco 2a/ddr-224hpa/b-d. I have a question on the rating of this machine. On the selector it has 120 to 300 that is max position. I the spec of the secondary transformer is only rated at 200 amps. Then it has some text on there saying (welding range inert gas 5-300) So is this a 200 amp stick ...
