I bought this welder to weld in my aluminum dump trailer. I was surprised by the power it has. Don't be worried that this doesn't have power, it will burn through 3/16 plate aluminum on medium settings.
I purchased this welder at Northern Tool for $629.99 on sale.

The Klutch® MIG/Stick 220SI is unmatched in capabilities and value. The inverter-based system offers increased power output from a smaller transformer, resulting in a super lightweight system that weighs up to 50% less than comparably powered traditional models. The lightweight and powerful inverter design makes this welder extremely versatile. From MIG to Flux Core to DC Stick, and even DC TIG welding capabilities, this one package can handle it all. Whether you're welding aluminum, steel or stainless steel, the Hybrid MIG/Stick 210SI shines through with performance you can count on.
I am not a Northern Tool employee nor do I own the copyright to anything Northern Tool or Klutch Brand. I just want anyone that needs a good welder and spoolgun to consider this unit, for $629.99. I am very happy with the weld and wire feeding.
I own aluminum dump trailers and the Klutch 220SI works very well on the 1/8' to 5/16' welding requirements for my business.
