Just to pile on, I have had one for about 30 years. It is great for just about all farm projects. Just make sure you use AC rated rods to make things work better. The only problem I've had is that the amp selector gets very stiff after many years. It needs to be taken apart and things freed up.
Then, about 15 years ago, I got the same welder in AC/DC configuration. Wow, it is nice to weld with DC. The amp selector on it is also stiff.
Finally, 5 years ago, I got a DC inverter welder. Now those are cream-of-the-crop devices. Light, great arc, butter smooth welds (when set correctly). The welders are an Everlast PA200 and, later, a Everlast PA300. A member on here, Shield Arc, convinced me to buy the 300 at a fantastic price. Very apprecative.
