This welder is not fancy, and not expensive, so it does not have advanced functions, however it seems a legitimate tool. The digital display for weld current is one feature it has which is great to have. I have not used it much but have tried both stick and tig functions. Adjustments seem to work and no issues like leaking argon for tig. I hope to practice with this a lot and hope it keeps working well. I read other reviews with other welders and some you want to stay away from. It now comes with a USA standard 110 outlet plug (early model, no digital display did not). [a lot more use on this model and it is performing perfectly, I'm actually amazed how easy it is to stick weld with it.]
