I installed a dedicated 20A, 110V outlet in my garage for an air compressor, that I also intend to use for this welder (obviously not at the same time). You need the 20A circuit to get the maximum out of this welder.
A normal 15A household circuit has a 15A breaker in the panel and 14 gauge wire serving several outlets, this 20A outlet uses 12 gauge wire to the single outlet and a 20A breaker in the panel.
I believe that using a 12/3 7M/25ft. extension cord will work fine, with minimal voltage drop, as it will continue the 12 ga. wiring through to the welder.
The type of plug isn't going to change anything in use - this welder has a conventional 110V plug on it, but if you have the additional amperage available it will carry it.
We do not recommend an extension cord because of the voltage drop they produce. This drop in voltage can affect the performance of the welder.
If you need to use an extension cord it must be a size #12 gauge or larger. DO NOT use an extension cord over 25ft in length.
