The miller syncrowave is an excellent multiprocess welding machine that can not only be used for MIG, spool welding but also for AC/DC TIG welding.

It is a good tool for both home use and commercial use. It works flawlessly when used on aluminum, steel and stainless steel.

Though there are other multiprocess that are cheaper, with the Syncrowave it is possible to do AC/DC TIG welding without buying a separate TIG welding unit.

Well, according to us Miller has thought through this model. And though there are some drawbacks I would argue there are far more benefits. So, if you have some extra cash to spend then buying this tool wouldn’t be a bad choice.
