I bought the 70 amp. The 70 amp and 90 amp looked identical in the store. After using it for a while I noticed a different set of screw holes on the bottom of the machine. I noticed that the isolation plate between the primary and secondary on the transformer wouldn't come out all the way. All that needed to be done to gain the extra 20 amps was unscrewing the transformer, moving it over to the other screw holes, and putting it back together. It was a 30 minute job.

Good morning Nova, thanks. I'v been thinking of Github too, where I have an account too.

This welding thing happened to you is funny, you did a good job!
