This machine works great , so far I have done 20ga sheet metal and it worked out just fine , I like the foot pedal better than the on torch control , I guess I cant say enough about this tig welder , for the money I don't think you can buy anything better , I have only run it on 220 volt power but it will run on 110 volt for those that don't have 220 , just wish I had more time to get out in the shop and work on stuff but after 12hrs out in weather that is 0 or below I don't feel much like getting out there , going to have to soon as the dead line for the build off is getting close
