I've had mine for about five years now. Works right, every time. Could not beat the price at the time. I did buy the model without the electronic wire speed controller.

Its controllable enough for thin sheet metal on a continuous basis and can handle high-amp welding when needed (just not continuously due to the duty cycle).

My only issues for this welder (other than the duty cycle, increasing the duty cycle dramatically increases cost) is the short length of both the power cord and the welding cables. replaced my power cord with heavier gauge and 25' longer cable so that I can bring the welder to the work. I will eventually replace the other cables as they are shorter than I like but you are given enough to work with.

I love the wire feed mechanism of this one over the Millers that I have had in the past. I would buy this machine again if needed.
